For users without any knowledge of ATC, there's a short beginner's guide. Full instructions for the simulation game Endless ATC:
Top view and side view of a correct ILS approach. In this example, a plane at 2000 feet approaches runway 27 at a shallow angle of about 30 degrees. If ILS mode is enabled, it will capture the blue ILS path automatically, and land. Note that the altitude of the plane determines the required distance from the runway: the higher the plane is, the further away it needs to be from the runway. Use the circles for a reference, and make sure to intercept the glideslope 'from below'.

Don't intercept the ILS at a too steep angle, or from above the glideslope.

Aircraft labels, runways, and the ILS
This timelapse can give you an idea of giving vectors for an ILS approach.

Below you can read more detailed instructions.
  • Sequence the randomly generated arrivals to the ILS (Instrument Landing System) of a landing runway. The runway is the thick blue line in the middle of the radar screen, and the ILS path is the thin blue line extending from the runway. Guide the planes to this blue line, far enough from the runway. In order to capture this ILS beam and land, a plane must comply to these conditions:
    1. the ILS mode of the plane is activated,
    2. the plane intercepts the ILS line at a shallow heading of 50 degrees or less with respect to the runway heading (in reality they use 30 degrees),
    3. the plane has to be descended low enough to intercept the glideslope; the blue circles mark the heights of 2000, 3000 and 4000 feet.
    The plane has to be flying on the localizer (the lateral ILS component) before it will capture the glideslope (the vertical component; the descend path of the ILS). Examples of correct ways to vector a plane to the ILS, are given in the app by yellow arrows, with the plane flying at an altitude of 2000 feet with ILS mode enabled. You don't have to guide the planes all the way in front of a runway; once a plane is on a correct intercept course to the ILS path, it will follow the ILS automatically to the runway by steering and descending.
  • When a plane is established on the ILS, it will be handed over the the tower and then you score some skill points. The amount of skill points you score per plane depends on your current skill score. You always get at least 0.1 skill points per plane handed over to the tower. The skill score represents how well you are managing the airspace and it also determines the number of planes you will have to control simultaneously, so a score of 8.4 will give you about 8 planes to control.
  • If a plane is too high on the ILS (flying above the glideslope) it will eventually call a missed approach. ILS mode is then deactivated. Try a new line-up at a lower altitude, so it will capture the glideslope from below. If a plane is about to land on a runway that is still occupied by another plane, it will go around: it climbs to 2000 feet and ILS mode is deactivated. Give it new vectors to the ILS, now with more distance behind the leading plane.
  • At the top left you see your current game score. This number is the maximum of what your skill value has been in the current game. So your score can only increase. Then there's also the high score: the highest game score you ever reached on your device (unless you cleared the app data or reinstall).
  • Departing aircraft determine their heading and speed themselves; they only require an instruction to climb to a higher altitude. This can be done, when its safe, by just one click to select FL130. Other altitudes can be selected but keep in mind that eventually the plane has to continue the climb to FL130. Optionally, a heading can be given by disabling 'SID' mode temporary. When you disable SID, the climb is also restricted to FL100. Make sure to activate it again and continue the climb so that the plane has climbed above FL100 before passing the boundary of the airspace. The airspace boundary is displayed as the outer circle (radius 30 NM). For New York, departing planes fly on a heading initially, so you'll have to manually enable SID to clear planes to the departure fix.
  • You can lose skill points when planes:
    1. fly too close to eachother (in general: overlapping circles and altitude difference <1000 feet),
    2. divert (leave the airspace at the 30 nm boundary), also if they are departures but fly at or below FL100 when leaving the airspace,
    3. abort the approach (runway occupied, too high altitude etc.),
    4. are delayed (not landed within about 40 minutes)
  • An aircraft label has the following lines of info:
    1. callsign,
    2. current altitude and selected altitude (in feet divided by 100),
    3. ground speed (in knots), weight category (medium [no tag],  Heavy or Super J), mode (ils/direct/hold).
    4. destination (if other than main airport)
  • When a plane is not in your control, it has a smaller label of just two lines.
  • When a plane wants your attention, it has a flashing blue ring, until you select it.
  • You don't have to hand off (or hand on) planes from/to the tower or other controllers. To keep it simple, planes do this automatically. Handoffs are possible, but not necessary.
  • You can drag from an aircraft to easily set its heading. When you then drag onto a beacon (grey circle) then it flies directly to that point and the DCT button illuminates. Directs can also be given by pressing the 'DCT' button: then it will snap to a beacon/VOR/locator closest to the selected heading. DCT is, like ILS, a mode that alters the heading of a plane automatically. If a plane reaches a beacon without further instructions, it will fly circles above it, like a holding pattern. Avoid holding planes because it will cause delays and crowds the airspace. Longpressing DCT will 'HOLD' the plane at the current position, if you think that's handy. Some runways have a beacon (a locator) on the ILS path; planes can fly direct to it but won't enter a holding there but continue. You can also drag from a selected VOR beacon to set a heading in which the plane must fly after reaching the beacon. Departures fly to a randomly chosen beacon and then continue ahead.
  • In some cases, the separation minima (1000ft/3NM) are reduced: planes may fly closer to each other when:
    1. both planes are on a different ILS localizer ('LOC' status), so independent parallel approaches are possible,
    2. one or both planes are under the minimum altitude (1600 feet),
    3. two departures are on a divergent heading of 15 degrees or more,
    4. just after a go-around you'll get a short amount of time to regain a safe separation.
    1. In general, don't let the 3 NM rings overlap when the altitude difference is less than 1000 feet.
    2. For parallel approaches, maintain a vertical separation of at least 1000 feet until both the aircraft are established on the localizer. For example, join the localizer at 2000 feet for one runway, and 3000' for the other. When the planes then descend to the runway, rule 1 (stated above) applies so no penalties are given even if the rings overlap!
    3. Longpress ILS to enable the ILS* mode, which means the plane will cross one localizer and intercept the next one. This can come handy when parallel runways are in use and you want to guide some traffic to the other runway for better traffic distribution.
    4. The number of planes you have to control is about the same number as the skill level. When the score increases above certain levels, new runways become active.
    5. Planes with 'RD' in their label (4th line) need to land on the secondary airport which has only one runway (this runway also has RD in the name, actually meaning EHRD or Rotterdam Airport). Regular planes, so without the 'RD' tag, may not land on this destination but have to land on the main airport: Schiphol. Landing on runway 06RD (the opposite direction) is not accounted for in the game, so only traffic via the northwest from/to RD is simulated. Note that the amount of traffic to RD is very low compared to the main airport. For London, the traffic rate to the alternate destinations (Gatwick, Luton and City) is a bit higher.
    6. Plane with destination 'EHRD'
      Plane with destination 'RD'
    7. The speed displayed at a plane's label is the ground speed, which is usually higher than the indicated airspeed: it has an offset increasing with the altitude (due to thinner air). When you change the speed, the label temporary shows the desired indicated airspeed instead, in yellow.
    8. If there is wind enabled, the wind speed increases with altitude. It will also affect track heading and groundspeed.
    9. Expedite a plane's climb/descend (that is: increase vertical speed) by doubleclicking on the altitude button when it's at its limit value.
    10. There are medium (no tag), heavy (H) and superheavy (J) weight planes. The heavy ones turn and climb/descend a bit slower, while their final approach speed is a bit higher.
    11. Due to wake turbulence, planes behind heavy planes need more distance than the general 3 NM circle. In this sim, wake turbulence separation only applies to planes on the localizer. The required distance depends on the plane category: if a medium flies behind a heavy, more distance is needed. There are 6 categories ('RECAT'), and an arc displays the required safe distance to a trailing nearby aircraft. If this limit is infringed by more than a mile, you risk a go-around.
    12. Planes are generated randomly, depending on the skill value you achieve. Runway usage is also randomly chosen at the beginning of a game. Tap the reset button (under 'new' in the menu) to start a new game. Your high score and goals are saved. In the full version, you can start a new game by selecting an airport.
    13. Planes below 3000 feet have the option to descend as low as 1600 feet to make short finals possible.
    14. Planes flying within a 15 nm circle from the field slow down to 220 knots (unless a speed instruction has been given earlier).
    15. Planes intercepting the ILS reduce to 200 knots. At 6 miles from the runway they reduce further to 160KT. And at 4 miles, they reduce to final approach speed. You can always reduce earlier if needed.
    16. Planes handed over to the tower may reduce speed further automatically, but only within 10 miles from touchdown while flying too close to a preceding plane.
    17. Changes to an airplane are applied when pressing the OK button, or when the plane is deselected. Pressing the C button cancels the current changes, and pressing C again deselects the plane.
    18. If you cap the skill value (by enabling custom traffic mode), then the skill won't increase higher than the cap value. The difficulty is then also limited, because the number of planes you have to control is equal to the skill number. This results in a more relaxed gameplay, and can keep the amount of traffic at a more realistic level (while in a normal game, the traffic rate can get to extreme levels, a big challenge!). If you lower the skill below 4.0 then the airspace will be closed entirely.
    19. In custom traffic mode, you can also switch to flow mode to set a constant flow of planes per hour from/to the main airport. For example, set it at 30 and you'll get 30 planes per hour departing, and 30 planes per hour arriving at the main airport. If you set a mininum and maximum flow rate, then the flow rate varies between those values, which results in alternating inbound and outbound peaks every hour. Manually increase the skill value first if you want more active runways/more traffic to secondary airports. There are also options to play a game without departures, or without traffic to secondary airports.
      Flow varies when a minimum and maximum value is set.
    20. You can score goals by landing a certain number of planes in a correct way, like 10 planes without separation incidents, or 5 planes without any mistakes (go around/divert/delay/missed approach/separation incident), or just land 100 planes in one game. However, to make it not too easy, you cannot use custom traffic mode if you want to score goals/set high scores. If you've used custom traffic mode, you have to start a new game first by using the reset button. In the full version, click on the currently selected airport to restart with a new game.
    21. The game is automatically saved when you exit or pause the game. Next time you start the app, the game will reload.

    Frequently asked questions

    Q: Runways 18C and 18R are too close to each other. How do I make good use of them without getting incidents?
    A: The approaches can be done completely independent; the trick is to intercept the localizers at different altitudes and at a large distance from the field. Read instructions above for more detail.

    Q: It gets way too busy, what can I do?
    A: Enable 'custom' mode in the traffic menu. You can cap (limit) the amount of planes you have to control to a certain amount, or set the number of planes per hour you want to handle.

    v3.9.8 (8 July 2019):

    • Choose between label styles: there's now a 2-line and a 4-line option, in addition to the default 3-line plane label. In real life, radar displays differ per country/facility, but in the game you can choose between 3 styles in the display menu.
    • The text at the bottom of the screen has a black background for better readability when planes overlap
    • Handoffs for departures are now only allowed above 3000 feet from the ground, to avoid (accidental) early handoffs and encourage the player to handoff planes when they're high&safe in the airspace
    • Lowered area restrictions at EDDF with 500 feet, to avoid issues with low GA traffic, and it's actually slightly more similar to the real life situation.
    • Added more hints to the beginner mode
    • Bugfix and minor adjustments.
    • Update 18 July 2019 (v3.9.9):
      • bugfixes for the recently introduced label styles, especially label 'C' seemed to cause issues in certain situations with planes in holdings
      • ability to move the sidebar to the other side using a quick&easy swipe from menu button
      • improved holding entry (direct, parallel and teardrop), and corrected the Lambourne holding at EGLL into a left turn pattern, as it is in real life

    v3.9.6 (25 May 2019):

    • more light category aircraft, mainly at North American fields
    • corrected Toronto departure headings to allow for parallel departures
    • better explanation of the meaning of several buttons for beginners
    • several traffic updates
    • bugfix to avoid a possible freeze when changing traffic mode
    • bugfix missing icon file
    • v3.9.7 (2 June 2019):
      • fix issue where planes did not go around while being much too close behind a preceding plane on the same loc
      • fix issue with private planes in Tokyo.

    v3.9.4 (9 March 2019):

    • Wake turbulence distance is more clearly displayed to the user.
      • arcs have a brighter color for better visibility
      • infotext at the bottom of the screen shows the required distance to the next plane on approach, for example 'wake -0.5 NM' if displayed when a plane is half a mile closer than it should be
    • Adjusted (increased) the traffic to secondary airports. The traffic flow to these airports depends on the skill value, but in the previous version the flow was pretty low even at high (20+) skill values.
    • Better mouse support on android; it should now work exactly the same as on the PC version
      • hover the mouse to see distances to other planes in the infotext
      • enable ILS mode by clicking left and right mouse button at the same time, scrollwheel functionality, etc.
      • v3.9.5 solves an issue where android app failed to start when mouse moves during splash screen.

    v3.9.3 (6 Feb 2019):

    • Added low contrast option, to reduce display issues on certain monitors (VA, OLED) with slow black->grey transitions. When contrast setting is at '0', the black pixels will be actually dark grey pixels, improving display quality when panning/zooming.
    • Enabled multiwindow support (android 7+) to allow for multitasking; could be useful on devices with large screens (tablets, chromebooks). App scales best in landscape dimensions, by design, because the options bar is on the side. Also added 64bit support on android, to anticipate to new Google Play store requirements (it shouldn't cause any noticable changes to the game, apart from a slight increase in app size).
    • Wake turbulence distance is added to text at the bottom when mouse cursor hovers above a near plane (and on android: when multitouch is used on two planes). When hovering over a near plane, the bearing towards the plane is displayed.
    • Bugfixes and traffic adjustments
      • More departures from secondary airports when flow mode is enabled (after setting a high skill first).
      • Flow limit increased to 180 planes per hour. Before it was limited at 120/h, but that may not be challenging enough when 3 landing runways are available (happens at KATL). However, departure flow is unlikely to keep up with very high flow numbers and will start to lag behind (a star will be shown to indicate this).
      • Fixed keyboard command for speed adjustment for departures.

    v3.9 (21 Dec 2018):

    • Added more weight categories, totalling 6 (as in 'RECAT' used in some places in real life), for more efficient wake turbulence separation, both on the localizer and time between departures.
    • Added occasional (rare) light traffic (labelled 'L') at several airports.
    • Wake arc will adapt dynamically to the required distance between two plane categories (instead of always displaying two arcs for 'H' and 'M' categories). 
    • Planes inbound secondary airports will have a slightly different (mint) label color, so they're easier to distinguish from planes inbound to main airport.
    • Bugfix where planes go missed approach at CYYZ + TZ when localizers were crossing eachother.

    v3.8 (14 Nov 2018):
    • 2 new locations! CYYZ and RJTT were added.
    • Customizable traffic rate
      • Set traffic mode to custom to be able to set a skill value and skill cap yourself. The skill value will determine the amount of planes you have in your control at a time (and it opens more runways, and it determines the amount of traffic to secondary runways).
      • Set traffic mode to 'flow' for a fixed flow of inbound and outbound traffic. For example, set it at 30 and you'll get 30 planes per hour departing, and 30 planes per hour arriving at the main airport.
      • Added buttons for 'no departure' mode and 'no secondary traffic' mode.
    • Customizable wind direction/speed/clouds.
    • Better runway change implementation.
    • More display settings: range rings, and XL font (android).

    v3.7 (30 Aug 2018):
    • Change runway configuration (by tapping the RWY CHG button, or F12) without risking missed approaches. Can be handy if there's weather near a runway, or the wind has changed. After a runway change request, it takes a few minutes before new approach clearances can be given.
    • Inactive runways are visible (in grey).
    • Removed doubletap ILS for LLZ mode, as it could be too easily selected by accident. LLZ mode is now hidden behind a longpress between the altitude buttons.
    • Android app targets Oreo and has an updated icon and full keyboard support.
    • Better departure capacity from parallel runways.
    • When selected, handed over planes still have the yellow target heading line visible.
    • Hold right mouse button to show estimated time for the plane to reach cursor position.
    • Adjusted transition altitudes for EGLL and EDDF.

    v3.6 (6 July 2018):
    • long press and doubleclick functionality of the sidebar is now also usable for the mouse and keyboard commands
    • planes can be cleared for the localizer only (LLZ mode) by typing LOC or LLZ, or longpress between the altitude buttons. This won't land the planes, it only avoids GS capture, so eventually full ILS mode needs to be activated as well.
    • doubleclick SID autoselects highest altitude
    • if player doesn't manually handoff planes, then pilots eventually won't notify user anymore when they switch frequency automatically, to reduce repetative messages
    • hover mouse above plane to show type and distance from selected plane, on android use second finger to show distance from selected plane
    • after a long delay planes will divert automatically

    v3.5 (14 March 2018):

    • planes can make turns greater than 180 degrees: instead of defaulting to the shortest turn to the selected heading, planes can now also turn 'the long way round' to a heading, making turns up to 360 degrees with one command
    • doubletap between heading buttons to easily command a 360 turn over right or left
    • separate savegames per airport: switch between airports without losing progress
    • adjusted penalty for separation incidents: constant 0.5 point reduction per incident + small time component (results in less skill reduction for long duration separation incidents)
    • smarter tower: it can reduce speed of planes (that are handed over) that are too close to a preceding plane (within 10 miles from touchdown); this could avoid missed approaches
    • added L and R keyboard commands for left and right turns, H can still be used for shortest turn, and T is now used for headings after beacon.
    • button added in menu to switch sidebar to the other side
    • speed will not reduce automatically to 220KT anymore if user has set a speed
    • faster speech rate when time multiplier is enabled
    • game starts paused when skill is high (12+)
    • for emergencies the vertical seperation is 500ft

    v3.4 (18 January 2018):
    • two finger pan/zoom (android)
    • green text at the bottom now fits on screen (using two lines of text when needed)
    • no automatic altitude change anymore when enabling SID mode (mainly affects KJFK area where SID is off by default; it should avoid unwanted climbs)
    • added a warning message before cap mode is enabled for the first time, because goals won't trigger anymore when cap has been used

    v3.3 (7 December 2017):
    • LFPG and KJFK airports added to full version
      • Paris (LFPG) has Orly (LFPO) as secondary airport, and flights over Paris city are only allowed at FL66 or higher.
      • New York (KJFK) has Laguardia (KLGA) and Newark (KEWR) as 'secondary' airports (although they're quite busy), and all departures fly on a heading instead of the usual SID mode, so you'll need to enable SID manually at some point to clear them to their departure fix.
    • reduced separation to 2.5NM for planes on the same ILS, closer than 10 miles from the runway; this avoids incidents due to compression when the preceding plane reduces speed
    • category 'super' aircraft now have a J in the label instead of an S
    • the skill value can be lowered (to reduce traffic), and decreasing it below 4.0 closes the airspace
    • text at the bottom of the screen shows the distance d from plane to cursor (when mouse is used)

    v3.2 (19 July 2017):
    • more departures, by having occasional simultaneous takeoffs when it gets busy
    • reduced separation requirement between two departures on divergent headings (15 degrees or more), to make simultaneous takeoffs possible
    • reduced separation requirement for a short period of time after a plane is going around; this avoids double penalties
    • Steam release (19 July 2017)
    • TTS speech queue improvements; readbacks come before new calls, and pilots will less likely 'interrupt' you while giving commands
    • easier expediting climb by doubletapping in the middle between the altitude buttons
    • incident alarm sound is now silenced when selecting an involved plane, to avoid annoyance

      v3.1 (2 June 2017):
      • Wake turbulence behind heavies.
      • additional android version released (see Play Store) with multiple airports and extra options
      • custom zoom by doubletap + drag up/down
      • optional high speed climb
      • automatic repositioning of labels for parallel approaching planes, to avoid label overlap

        v3.0 (7 February 2017):
        • Pilot speech added.
        • Manual handoff of planes (optional).
        • Move sidebar to the other side by doubletapping the menu button.
        • Plane types are now visible in the infotext at the bottom of the screen.
        • Share your stats via the button in the goals screen.
        • In the PC version (see here, released on on 11 Dec 2015), restricted areas and multiple airports were added (Atlanta, London and Frankfurt).

              1. Just installed it, nice game! Thanks for posting!

              2. Hey -- I've been messing with this app for a few days and I love it. Most of the above I figured out on my own based on the on-screen tips. One thing I would wish for it is a more reliable way to save, exit, and resume -- sometimes when I suspend the app I can resume from where I left off, and sometimes it resets. Other than that, it's a blast and very well done. Thanks!

                1. Hi Rob. When pressing the back button while the game is paused, the game exits completely. When pressing the home, or when switching tasks, the game is paused and android keeps it in its memory until it the game is activated again. But when android runs out of memory, it automatically kills paused apps.

                  A save game function would avoid this, but I haven't done this because its a lot of work (creating a function that writes everything to a file and one that loads it). So far I only store the high score value.

                2. Thanks for the reply. I know you put the app up for free and thus you're pretty much volunteering your time for development & support. But I for one would be willing to buy a full version for a reasonable price if it could save & resume more reliably. :)

                  I also made two other suggestions in my Google Play review which I'll mention here -- (1) a means of moving the command panel to the right side, so I can tap the buttons with my right hand (most of us are right-handed, after all) and not obscure the radar screen while doing it; and an option to limit the number of planes in control at once, so I can sit there mindlessly and truly enjoy "endless atc" instead of dealing with an ever-increasing level of sheer madness.

                  All that being said, I appreciate the work you've done and it's a great product as-is. These are simply suggestions for further development, should you decide to invest the time and effort. Thanks for a truly enjoyable and well-conceived ATC app!

                  Cheers, -R.

              3. As a former en route controller myself this was a lot of fun trying my hand at terminal. Keep up the great work. Been looking for a good tracon sim for a long time.

                Any plans for sound?

              4. Hello, great app, but please add STAR, add SAVING POSITION :-)

                1. Games are now saved! About STARs: as far as I know, on big airports planes are usually vectored to the ILS. On Schiphol for example, only at night hours complete STARs are flown.

              5. Hi again -- I have been VERY pleased to see that my suggestions for save-and-resume as well as capping the skill level have been incorporated. This is truly a five-star app -- nothing I've come across in the realm of ATC simulations online (for phones or PCs) has even come close. Thanks again for all of your hard work.

              6. Bert Horn April 23 2014

                I have been playing Endless ATC for about 5 or 6 weeks and I love it. I'm 77 and used to spend many hours a day watching TV. Now I watch a little TV and spend hours playing your game. I did encounter one problem the other night which I didn't understand. I was trying to land a KLM heavy flight but it kept making missed approaches. I put all other flights on hold and tried many combinations of speed and altitude(4000 ft and below) approaching the ILS from entry points between the altitude markers and above. Nothing seemed to work until by chance I made my approach from the other side of the ILS beam. That worked fine. Is this by design or just an anomaly? In any case I would love to see this game on my PC since it would be so much easier to see the plane info that is displayed next to the plane. My old eyes require a magnifying glass because I am using a smart phone since I do not own a tablet computer. It would be worth paying for the game to help cover the expense of your time and I would guess that you would get many new users. Another possibility would be to display the actual altitude and speed on the side panel to make it readable. Thanks again for a great game. Bert Horn tried to enter my name and url but I don't know what my required host name would be.

                1. Hi Bert, thanks for you comment. About the missed approach issue: it shouldn't matter from which side the plane intercepts the localizer. If it keeps missing approach, it's either a bug (please check for updates in the Play store), or the plane is flying too high to catch the glideslope. Try intercepting the localizer further away from the runway, for example at the 3000 or even 4000 feet marker, while flying at 2000 feet. Then it has more miles to stabilize on the localizer, so it can catch the glide later on when passing the 2000 feet marker.

                Is there a Windows PC Version avbl?

                1. This comment has been removed by the author.

                2. Hi, a PC version is now available.

              8. Greetings,

                This is a 4star game, it does what it says with a good degree of accuracy. But I've uninstalled it rather quickly for one reason: I was about to suffer RSI on high skill levels in order to keep things running.

                So these are my comments on the game:
                -The workload is too little (almost boring) at the beginning and becomes extremely high near the "end" (almost insane).
                -Airports are black holes, they "absorb" aircraft without letting them go ie too many arrivals, too little departures.
                -Controlling departures as well (besides altitude assignment) will be also interesting.
                -Nagging the player once when approaching a point and once more when entering a holding pattern is useless. What really interests real life controllers (especially when they get busy), is crossing the finals. And as far as I am concerned, if a controller forgets a plane without letting them know to "expect vector across finals", the plane will call the controller.
                Finally, when the TMA becomes crowded, more than one controllers could be in charge. For example, LGAV might occupy one departures controller (DEP) and up to 3 arrival controllers (ARR1, ARR2, ARR3), two intermediate and one final director. Could that be a multiplayer idea for the future?

                Keep up the good work,


                (PS: I didn't rate this app and I don't have any such intentions, since I'm not willing to create a g+ account just for rating apps in play store; sorry.)

                1. Hi Stelios, thanks for your feedback. I will consider some of the points you made for future updates.

                  What started as a simple game has now become quite realistic. For some players it can't be realistic enough, while others play it more like a puzzle game, with increasing difficulty.

                  And just to be sure: you can speed the game up (2x-4x) at the beginning, and later on limit the rate of arrivals for a more realistic workload using the cap option.

                2. Hi startgrid, I know how it started; that's how I started my own ATC simulator for PC about 7 years ago ;)
                  Nothing public yet but I will try soon.

                  About time speed yes I know but I totally missed cap so thanks for letting me know! I will be glad to see some of my recommendations implemented in one of your future releases.

                  Once again, nice job, keep it up.


              9. Great game. Played and loved ATC2 simulator on the PC (uses voice commands) and this is the closest atc game that's most similar on android I've found. Cheers.

              10. what is critria for a diverted plane? thx.

                good game

                1. An arriving plane is diverted when when it leaves the airspace at the 30 nm boundary. A departing plane is diverted when it leaves the airspace at the boundary while flying at or below FL100.

              11. Hi, this is a great game, really well done.

                As far as I can tell, the runways are randomly generated, but the beacons are always in the same place. Therefore sometimes the beacons are in really unhelpful places. Is there any scope for having completely different setups with regards to this?

                Thanks a lot.

                1. Hi Liam. The layout is based on Schiphol airport. For the beacons, I use actual locations VOR/NDBs and some fixes found on charts online. Some runways have a locator too. The fixes near the perimeter are mostly used for departures.

                  To avoid a cluttered screen, there are not too many fixes (only the most used ones). Headings should mainly be used the guide the traffic.

              12. Nice ATC Game ,is a PC Version exist ?

                Please is possible to add pilots voice in this game for a perfect réality. tks

              13. The only thing i miss is a donate button. Amazon wish list maybe?

              14. Great game! One plane that took off made an emergeny-call and wanted to return to the airport. Does that just happen randomly and can a plane have an emergency when the skill-cap is on?

                1. Do you get extra skill level points by vectoring him bac quickly to land?

                2. Same amount as normal arrivals.

              15. Hi again! LOVE the updates. One small thing -- pilots inbound to Schiphol would not care nor report that they are crossing the EHRD loc. Thanks!

              16. Hello,
                Des this app work on thé Galaxy Tab 4? 'Coz I votre trouble when I'de like to ans were or guide thé aircrafts.
                Thanks to reply me quickly.

                1. I don't know, but if it works, you should directly see a radar screen with one or more planes on it. See the images above.

              17. Rob. I am pilot for a major airline. You have nailed it. Love the game.

                Question: When you have dual approaches running. You select an aircraft to land 18r ILS (he is coming from the west) . However, due to traffic you need him to switch to 18c. How do you reset the ILS for 18c. I tried reselecting ILS button, vectoring the plane to the east and vectoring him to 18c. However, I could not get him to change to 18c. He always indicated 18r. It really messed up my traffic flow. LOL.

                OTHER USERS. I am scoring in the 25.0 level. Are you doing better? Techniques?

                1. Thanks!

                  Answer: a plane is assigned to the nearest runway he's pointing at when you enable ILS and press OK. This makes it easy to play the game, however it's indeed a bit tricky to assign planes coming from the west to the eastward runway. You could disable the ILS clearance (and press OK), let the plane pass the localizer of 18R, then enable ILS again somewhere between the localizers to assign it to 18C. Best practice though, is to avoid this situation by balancing the amount of traffic evenly earlier on, for example by dividing traffic from the southwest between 18R (right hand circuit) and 18C (left hand circuit after SPL).

                2. So, I have found that when you select ILS. The plane must be below the ILS feather line, to capture that ILS.

                  Example: 18R and 18C are active . A plane is being vectored from the EAST to 18c. If you look at the 18R extended line. (It is higher than 18c because of the runway offset).

                  If the vectored Plane is above the 18C extends line and you select ILS. It will always capture the 18R ILS course. So, it would be nice if you could somehow override this and tell the aircraft which ILS you would like it to capture.


                3. This issue is now solved by an update. Before, when you wanted to give approach clearence for 18C from the east, while being far from the runway, then the plane would be abeam the 18R localizer first. Hence the ILS for 18R was selected before the desired 18C ILS was detected.

                  From now on, the ILS can be detected further out from the runway, so even when the plane is not yet near/abeam the localizer. This makes selecting the correct runway more predictable.

              18. Adding the Hi Res data tags has helped reduce clutter for high end screens. Thank you. M

              19. Its an awesome game with realistic situation and separation rules, CA alert is sensitive as well, ILS intercepting angle and glide is pretty accurate as well. Future suggestion could implement real airport runway configuration or enable user to decide the heading of the runway :)

                Overall great job

                Long time fan

              20. A truly amazing game. Congratulations on a job very well done. I'm a pilot and really missed an accurate ATC game for Android, you nailed it.

              21. Awesome game, i am spending a lot of time on it... 2 questions... 1) what us the high-score of the "experts" here..... 2) I get the comment "is delayed.... what does that mean? what did i do wrong?

                1. When a plane hasn't landed within about 30 minutes after entering the airspace, it's classified as delayed. So to keep flawless, the player also has to be time efficient. At high traffic rates that's pretty hard.

                2. Anonymous, I'm curious about high scores too. The best I've managed is 21 or so - after that run out of time and space to control all the aircraft, and start to have separation incidents. The Endurance III goal is the last one to get.

                  If people are going higher it would be great to see some video of how they manage that.

              22. complement to question 2: I get "[callsign] is delayed" sometimes when there is a lot of traffic.

              23. Great game! I have been using it and enjoying it for a long time. But with the new update, I noticed the hold button for aicraft is missing. May we please have it back?

                1. The 'hold' button next to the 'ILS' button was a bit too prominent, considering that holding planes inside of the simulated airspace is very rare, let alone holding at any position. In real life, there's a published holding at SPY, but it's seldom used.

                  On the other hand, it seems some player would like having the option to hold anywhere back, so maybe it will return in the future in some way.

                2. Holding a plane at it's current position is now possible by longpressing the DCT button.

              24. startgrid, many thanks for a very enjoyable game. I'd love to donate via some mechanism other than bitcoin, have you ever considered Paypal or similar ?

                The usual layout at Schiphol makes for lots of variation, but adding other airports would a be great addition. The interaction between Schiphol and Rotterdam can be fun, so maybe San Francisco with San Jose and/or Oakland would also work.

                1. Thanks. A bitcoin address was an easy addition. For now I created a PC version, allowing donation via Paypal also.

              25. Any chance of developing new airports to try? Great game - current high score is 27.5! Andy

              26. I understand the H at the end of a callsign means heavy, but what is the N?

              27. I also see a *F on a callsign. What is that?

                1. The numbers and letter(s) in the callsign are random and have no meaning, but the letter after the groundspeed means either medium or heavy.

              28. Are you a ATC or just a game developer?

                1. Developer with connections to actual ATC.

              29. Why do landing at some run way it says wrong airport? How to recognize correct runway?

                1. One runway, namely '24RD', is located at a different airport. Some planes have an 'RD' tag (see image above), which means they must land at '24RD' and not some runway on the main airport. Planes without the additional RD tag must land at the main aiport.

              30. this is the best atc game I have ever seen! love it!

              31. This comment has been removed by the author.

              32. Love the game!! Can you please do an Atlanta Hartsfield-Jackson airport or Chicago O'Hare layout?

                1. Thanks! Maybe eventually, but I can't give a roadmap.

              33. This comment has been removed by the author.

              34. HI, guys!
                Well..I'd like to say, that I'm really impressed!
                I'm about to graduate University of civil aviation soon and finely become an air traffic controller, so I do know something about this things.
                So, it's really amazing! I've installed this game for about 2 years ago and I'm not going to delete it because it's very cool.
                I have a question also. What about prohibited areas? Are you going to add some?

                1. Thanks. Good luck!
                  I may add areas in the future, as long as it doesn't get too complicated/cluttered on small screens.

              35. How does the text to speech output work?

                1. For now, this is for the PC version only. In the menu, set sound mode to 2 or 3 and it should work.

                2. Is it possible to change the voice?

                3. This comment has been removed by the author.

                4. Update. It now changes voice automatically. For best results, both US and UK language packs (Windows) should be installed.

                5. And now voices are also added on android. To change the voices, see the android TTS settings for the UK and US languages.

              36. Hi
                Are you going to add the new airports to the Android App aswell? I´d like to paly them whereever I am...Not only at PC

                1. I understand. The plan is to bring it also to android in some way, yes.

                2. Hallo again,
                  Can you say how long it will take until the update will be released for android?

                3. This comment has been removed by the author.

                4. Hi startgrid
                  It's amazing! I love the game after the update. Thank you very much for programming this game. I think the price is very fair, it could even be a little bit more expensive.

                  I love London the most, because there are 4 different airports and the airspace are very clear. Atlanta is very challenging in my opinion. Frankfurt is nice as well.
                  I am looking forward for more improvements and maybe even more airports?!

                5. PS:
                  Forgott to mention a bug I noticed. Sometimes it happens, that two planes on parallel localicers have a sepperation incident even when they are handed over to tower. I am not quite sure weather it's a bug or weather I am doing something wrong, but it's very annoying.

                6. Nice feedback! About the possible bug: planes on different localizers should indeed never trigger an incident. Maybe in your case one plane was not (yet) nicely stabilized on the loc, but still turning? Otherwise, let me know the runway combo and I'll doublecheck.

                7. Hello,
                  Why did you remove the wake turbulence behind heavies/supers? Or is it just a bug? For sure they are gone, but I liked them very much because it was very challenging :)

                8. Not removed, but they only go around if they get more than one mile under the minima, to have some margin.

                9. Ah ok. I think it was better when you had the indication rings behind the airplanes...

              37. One more question ;)
                I think it would be cool if you could set the amount of planes per airport yourself. This would be very cool for maps like London, where you have 3 airports. At the moment there is nearly no traffic on Rotterdam airport :(
                Do you think that's possible?
                (For example 75% at EHAM and 25% at EHRD)

                1. Thanks for the suggestion. Now, the amount of traffic to RD is indeed quite low (like in real life). For London the amount is a bit higher. The traffic rate is proportional to the current skill value.

              38. I like the PC version, except I found that there is not a "Reset" option to reset the game. Please correct this as soon as you can. Thank you, David B.

                1. When you click on an airport in the menu, a new game is started, unless 'cap' mode is enabled AND you select the same airport: in that case, only the runway configuration is changed. To reset, disable cap or click on a different airport first.

              39. On the Android version I got a plane with an Engine Failure, but it had not ILS option. How should I handle that?

                1. Wait until the pilots are ready for approach. ILS option should appear after a couple of minutes.

              40. If the game is updated, you need to reinstall the game?
                Or it updates automatically?

                1. To update, download it and overwrite the old files. Alternatively, if you use the app, it updates automatically.

              41. Can you add San Francisco and Munich please?

              42. Hi! I really love your game! Thanks for this!

                There's a little issue in Atlanta (I think). Sometimes, two planes arrive from the same location, one at level 110 and the other at 120. The last one keeps at 120 no matter what a do! It really refuses to go down. After a while, it says goodbye and I lose comm with it. Could it be a "inspector" seeing if I'm doing crap things (lol)?

                Again, thanks for you great job in this game.

                1. Thanks for your report! This issue was fixed last week, so please redownload the game and try again.

              43. Endless ATC in my opinion is the best ATC game out there,but i tink there`s an issue at Frankfurt.Planes come from the north,while at the real airport they don`t.Can you fix this, please?

                1. Sure :) I'll make adjustments to EDDF to make less likely for planes to arrive frome the north. To be included in a future update.

                2. Thank you very much

              44. Bonjour, merci pour votre travail, ce jeu me plaît beaucoup, installé sur ma tablette cependant j'aimerais aussi l'avoir sur mon Android Huawei mate 7 mais impossible... Auriez vous s'il vous plaît un lien pour une version précédente.. Merci beaucoup

                1. Merci! Mail me if you want to try an older version.

              45. Hey! Very good game, I just purchased the new Android full version!
                Is there any plan to have custom zoom level? Or a further level, at least, it is very crowded at times.

                1. Hey, thanks! Yep, that is planned for a future update.

              46. How do you view the full message from the pilot? At the moment the text gets cut off instead of going to a new line and I can't see a way to expand it. Also this is an awesome app, have become throughly addicted - congrats :-)

                1. Yeah, that's a small glitch on phones. Will try to condense the subtitle even further. Thanks :-)

              47. Sometimes it is difficult to see whether an aircraft is Heavy or Super because it is directly above/below another aircraft. I suggest that when an aircraft is selected, populate the display near the top left of the screen (below score) with the info about the selected aircraft.

                1. Agreed, I'll make improvements on label visibility in a next update.

              48. Hello, is it allowed to ask about your planes for the future of Endless ATC? Which features will be added? Thank you for your amazing work again. It's getting better and better over time :)

                1. Currently looking at ways to increase the departure capacity, e.g. by having simultaneous takeoffs in different directions. Trying to make it a little bit better each update :)

              49. Really love this game, will there be any ios or macos version in the future?
                Also it will be nice if the map is a bit bigger.

              50. Thank you! ios/mac is unlikely. Thanks for the suggestion.

              51. Awesome game, just purchased the Android version.

                Shouldn't the airspace floors be


                So as an example, "35 or higher" could be


                Instead it's currently


                1. Thanks. That notation could also be used. I chose to use the current notation to show the minimum altitude in areas, for all planes ('X') or special planes ('tag'). For example 25/LC says the ceiling of the tower zone at London City is at 2500 feet.

              52. Hello,
                Are there any plans for the future of Endless ACT ? I think it would be very nice to have more airports available. For example San Francisco( whole bay area?) Or New York with all 3 airports?
                Thanks for the amazing game!

                1. Hello. Yes, more locations are likely. Thank you.

              53. Hi,

                I have played both version on android and steam.
                Is this possible for you to add the 'new' button to the PC version? As i can't find this thing in the game. It would be nice if you can start from zero again if you make a mess in the game.


                1. Hi. If you select an airport, a new game is started. Yes, maybe this would be more clear if there was a dedicated button.

              54. Hello,

                really love this game, I play it since the first release but you reallty should add STAR on the simulator.
                I mean, it's true that in busy airport vectors are needed. But just at final moments for sequence, before they usually stay under RNAV STAR (like in Roma Fiumicino). When, on the game, you have 25 aircraft under vectors it's just crazy!

                Anyway best approach simulation

                1. Hi Davide, thanks for your input. Indeed, the game is limited to vectors and ILS approaches, while in real life there are more options. This makes the game easier to pick up and control, and it's still pretty close to real life operations (for example, at Schiphol all planes in the terminal airspace get vectors, except at night when it's quiet, only then RNAV transitions are used). But this may differ per facility.

                  In any case, 25 aircraft is very busy, that would IRL require more controllers on different frequencies.

                  Anyway, I'll keep your suggestion in mind, but I also like to keep the game simple!

              55. Hello, I´m Alonso i have 16 years and i live in spain.
                I love your game; it were fantastic if in the next updates you add spain airports like:
                Madrid(LEMD) or
                Barcelona TMA ( Barcelona El-Prat(LEBL), Reus(LERS), Girona(LEGE) and Lleida(LEDA)) or
                Palma TMA (Palma de mallorca (LEPA), Ibiza(LEIB) and Menorca(LEMH) or
                Canarias TMA (But Canarias TMA Will be crazy too much airports haha) or any airport of spain; it will be fantastic. If you have any question of my idea write to my e-mail:

              56. For planes on the ILS, it is quite hard to determine the position of the arc that indicates the minimum separation behind a heavy/super aircraft when it gets busy. Although it is still visible if I zoom in, it waste time to do it. My suggestion is to have the arc 'glow' yellow if the plane is on the ILS and it is tap by the player so that the arc can be more visible.

                1. Agreed, I'll change the color to make it better visible.

                2. Thank you for the update, really love the yellow arc. It make me play much more efficiently (especially at KATL with score>25).
                  But I like the colour of the buttons were before, it is now a bit too sharp for my eyes. The version before is more "clean" I guess
                  But this is just my personal preference, really enjoy the game

              57. Een super simulatie! Simpele interface en super realistisch.

                Ik durf het bijna niet te zeggen (want het is al vaak gezegd) dat ik het een goed idee vindt om STARS toe te voegen. Inderdaad irl gaat het via vectoring, maar het zou wel fijn zijn als de kisten via de transitions de sector binnenkomen, dus via RIVER en SUGOL etc. Geeft net iets meer structuur op de inbounds.

                Maar bovenal een super game! (ook zonder SIDS en STARS)

                1. Dank je! The traffic enters (more or less) via one of the three fixes, like IRL. Only approach control is simulated here; the three fixes/holdings are therefore located just outside of the airspace. But for the London area I decided to zoom out a bit more to add the four initial fixes/holding stacks to the controlled airspace.
                  Transitions to the ILS are indeed not implemented, but that keeps the game more simple, and vectoring is more fun :)

              58. Hello,
                I played Endless ATC. It is really nice!
                I'm Japanese, want to spread this game thinking in Japan.

                So I translated game manual to Japanese,

                and I maked tutorial movie. Two virtual newsreader girls explain about basic rules.
                (Sorry, It is Japanese only. Please use Youtube's auto translate if you'd like...)

                That is the best ATC simulation that I ever played. I'll be cheering you on !

                1. Hi Takaty-,
                  Nice video, well done! I think you explained the game very clearly for new players! Thanks a lot for the support!

                2. Hello.

                  I tried Endless ATC V3.5. and there are some questions.

                  1. Is there shortcut key for instruct a 360 turn ? (same function to double taps)

                  2. After boot, Appear airplanes when first pause. but second or later, no appear airplanes in pause. and screen slide to right under. is it some function like screen saver...?
                  (personally, I like green screen of before version...)

                  I need to update Japanese manual. I'd appreciate it if you could teach me that.

                3. Sure!
                  1. Not really, but you can use the L or R command without giving a heading to make a 360 turn. Works if a plane is not already in a turn.
                  2. Indeed, the pause screen was changed, so now you can have a look at the radar while taking a break. When pausing again later, the planes will not appear; the idea for this is that repeatedly using the pause function cannot be used as an 'exploit' to slow the game down/make it easier. However if this feels inconsistent to players I may revert it.

              59. Thank you for answer my questions. I added description in Japanese manual.
                I continue cheer new players and you !

              60. Hello,

                I find Endless ATC really good! However since the last update I can't reset the game, it just picks up from where I left off. How can I solve this?

                Thank You!

                1. If you click on the selected airport button, the game resets. Thx!

                2. Yes, I've tried that but it continues on all airports, it doesn't reset at all. Perhaps I should re-install?

                  Thank you for the prompt reply!

                3. Shouldn't be necessary. What happens exactly when you repeatedly click on the EHAM button, for example? Here it just restarts on every click.

                4. So what happens is that I start the session for let's say EDDF and it builds up to a certain level, let's say 20 and at that point I exit the game. Next time I start the game it continues at the point where I quit. Before, if I wanted to re-start the scenario and start all over again, all I had to do was to select different airport, and then again switch back to EDDF and scenario would start from scratch.

                  But now, that doesn't happen! It doesn't reset on any airport but keeps remembering each position for each airport.

                  I've tried re-installing the game via steam but that doesn't help, strangely!?

                5. That's as intended; switching airports doesn't reset anymore, allowing you to play different airports without having to start over each time you switch. But resetting should still happen when you press current airport button again. So pressing EDDF twice should always make it start from scratch. Otherwise, something is wrong!

              61. "Emergency Separation
                If, during an emergency situation, it is not possible to ensure that the applicable horizontal separation can be maintained, emergency separation of half the applicable vertical separation minimum may be used. This means that a 1000 ft vertical separation minimum may be reduced to 500 ft and 2000 ft vertical separation minimum may be reduced to 1000 ft. All flight crews concerned must be advised if emergency separation is used.

                The use of emergency separation is described in ICAO Doc 4444, 15.7.1."
       from Sky Library

                Came across this paragraph a while ago, don't know if this is something you would like to implement?

                1. Sure, it's only a small change that doesn't affect normal gameplay.

              62. Hello, is there any chance to have a IOS version?

                1. No, I don't have the knowledge and hardware to do that, unfortunately.

              63. Hi. I'm really enjoying your game and have purchased the full version for Android. You've done a great job on it!
                One small issue I have is that I play on my Galaxy S8+ and it has rounded corners on the screen. I've noticed that the game doesn't take account of the rounded corners and so the text on the screen gets cut off. Could you please adjust the game to recognise rounded corners and adjust the display of text accordingly?

              64. Hello, when the update will be released

              65. The planes missed approach because runway changed. Could this be avoid? I didn't notice any prompts though.

                1. Yep, in the latest version this should not happen anymore; planes will continue their approach, even if the runway is not active anymore.

              66. I've notice that planes that are coming from US/CAN and Ireland sometimes arrive from the east at Lam and Big which Irl it doesn't. They would arrive from the West at Bnn and Ock so could that be fixed in a future update. Planes that are flying from Europe will arrive via Big and Lam, planes from asia only use lam. Also planes that are coming from the West to Ock also flys direct from the left of Ock and not from the south.

              67. Also with egll cpt sid 09r departures the plane goes left instead of right which is what they do irl so hopefully that can be changed but for now I just vector them to the right so it does cause problems with the plane arriving from the left.

              68. i think you should look up flightradar24 and see the different approaches and where each airline comes in from because in the simulation i see planes that are suppose to be flying from europe flying from the west via bnn/ock when they should be arriving from the east. same thing for the departure,airlines like delta and american shouldnt be flying east.

              69. It is a great job, I like your posts and wish you all the best. and I hope you continue this job well.

              70. Hi
                What is ils*?
                Whats the diffrence between ils and ils*?

                Thanks for your support

                1. ILS is if there is only one localizer, but when there are 2 of more, and you Want the plane to cross one localizer and intercept the other, you have to use ILS*. And if there are 3 localizers (like in KATL) you have to use LLZ

                2. How does LLZ help in 3 parallel rwy situations? Give an example.

              71. Any plans to add KLAX airport?
                That would be awesome.

              72. Hi, how often do you update the traffic (the airlines and airplanes that fly to an airport) because i saw a Delta B744 even though they are retired

              73. Very well done. Would be interesting to see Santiago Airport (SCEL) in this sim, because of the Andes mountains.

              74. Inbound aircraft assigned a waypoint/fix how do you know which airport they are destined for?

              75. Good Afternoon, As a retired controller, this app is very well done. Better than some ETGs and TTGs. How do I obtain the updates and how do I download them

                1. Thank you! If you use Steam or Play, updates are automatic, but if you use you can download and overwrite the files if a newer version is published.

              76. Hi, can you add SAEZ/EZE (Buenos Aires Ministro Pistarini Intl. Airport) and SBGR/GRU (Sao Paolo Guarulhos Intl. Airport)? Because this airports are the most importante of latín América and SÁEZ has 2 sec airports and SBGR also 2! And the y are 2 very excitante airports. I would love this game if you add this airports!!! Thank you very much!

              77. When the Google Play update appears

              78. Please increase separation circle for heavies. I vector extremely close and without a visual barrier I end of giving way too much space. It's maddening to be working on a 100 or 200 error free landings only too hear a missed approach due to following too close.

                1. A little arc is displayed behind heavies to show the required distance, but I'll try to make it more clear in a future version. Hovering with the mouse shows the exact distance in the infotext line.

                2. The spacing of that arc jumps depending on whether the following plane is on local. Click ILS, it it moves. What gives?

                  Also, planes with a J designation fail too land because they're going to fast. I am able to land all other planes at 2k feet 250 knots. If there is a max speed for these planes at 2k feet then please limit their max speed on ILS.

                  By the way, I enjoy getting a slow plane from time to time. It really taxes my abilities and I enjoy the challenge.

                3. The arc distance depends on the category of the next plane, but the game has to guess which plane will actually be the next one. For planes on the ILS that's easy, but otherwise it looks for the most nearby plane as the best guess.
                  Also, I'll adjust the J planes behaviour so they reduce a bit earlier.

              79. Endless ATC: How do pause and how do you reset the game previous v had pause and reset

                1. Press ESC to pause (on android, press the back button). To reset, go the the airport menu and press the current airport again.

              80. Absolutely wonderful post! What a perfect concept. Thank you ReviewBlogAppeal

              81. Great game! I purchased the full version for android. I'd love to see some additional airports added over time. SFO or LAX would be my vote. Thanks Mr. Startgrid.

              82. What is Radio Sweep in Endless ATC? I don't understand, please explain about what it will do in the game?

                1. Radar sweep is the time between the plane position updates. It simulates a rotating radar antenna. You can set it at 4.5 seconds for a more realistic experience.

              83. I got a separation incident for two planes that were handed off. Why?

                1. Thanks for the feedback, it's as designed, but may need some clarification. Plane separation, from the minimum altitude to the top of the airspace, is the responsibility of the player. Handoffs are optional, and should only be used assured that no incident will occur after. For departures, it's therefore best to hand them over just before they climb out of the airspace, to be able to resolve any conficts yourself. Perhaps the H/O button could appear later (at a certain altitude), or better hints could be added.
