Basic instructions for the simulation game Endless ATC:
(updated: 11 April 2018)

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,  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 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 heavies need more distance than the general 3 NM circle. In this sim, turbulence separation only applies to planes on the localizer.
      • behind a heavy: 4 miles for a heavy, and 5 miles for a medium aircraft
      • behind a super: 6 miles for a heavy, and 7 miles for a medium aircraft
      • if these limits are infringed by more than a mile, you risk a go-around.
      • when a heavy plane is selected, two arcs display the required safe distance to a trailing heavy and medium aircraft.
    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 into the 15 nm circle slow down to 220 knots (unless a speed instruction has been given).
    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 your skill value by using the cap button, the skill won't increase higher than the current value. The difficulty is then also limited because the number of planes 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 for a single air traffic controller. Without a cap, the traffic rate can get to extreme levels, and the challenge is to manage that as long as possible! If you hold the cap button, the skill value will decrease, and below skill 4.0 the airspace will be closed entirely.
    19. 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 the cap mode if you want to score goals. If you used cap but want to score goals, 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.
    20. The game is automatically saved when you exit or pause the game. Next time you start the app, the game will reload.

    Game settings

    • Simulation speed can be set at 1, 2 or 4x.
    • Heading line can be set at 0 to 5 minutes.
    • Separation ring with radius 1.5 nm can be switched on/off/auto (nearby only)
    • Skill value can be capped, so the traffic rate is reduced.
    • Font size of the labels can be adjusted.
    • Doubletap to zoom in/out
    • Doubletap the menu button to switch the sidebar to the other side.
    • Sound can be set at mode 1 for alerts, 2 for speech, or 3 for speech with readbacks.
    • The full version also has multiple airports to choose from, with altitude restrictions, and optional weather and radar delay settings.

    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 'cap' mode in the menu. This keeps the amount of traffic to a constant level. Hold the cap button to lower the amount of traffic.

    Changelog

    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
    • larger margins between departures and between arrivals, adjusted initial climb altitudes for Paris and Atlanta for a smoother traffic flow
    • 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 (PC version).
    • button added in menu to switch sidebar to the other side
    • minor graphical changes and performance optimizations
    • v3.5.2 (23 March 2018):
      • speed will not reduce automatically to 220KT anymore if user has set a speed
      • heading bugfix for holding at current position
      • added hint on how to start a new game
    • v3.5.3 (11 April 2018):
      • bugfix for OK button sometimes being yellow for no reason
      • 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)
    • the blue text of a selected plane remains visible till OK is clicked, and it is displayed at the front of the message queue to make sure it's visible
    • 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
    • yellow wake arcs for clarity
    • skill reduces a bit slower during incidents
    • minor adjustments to the sidebar looks, for example the altitude button may have an arrow symbol instead of a plus, indicating that the maximum value will be selected
    • a couple of TTS pronunciation adjustments

    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. In real life, the airspace is very complex due to the large amount of traffic/many different airports. Planes from JFK often steer eastbound, on a certain climb route (to avoid getting near the other fields), then get vectors, and finally they are cleared to a departure gate. In the game, this is simplified to one heading and the option to enable SID mode when the it's safe to do so. 
    • 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
    • added more SIDs to the London area
    • various minor adjustments
      • category 'super' aircraft now have a J in the label instead of an S
      • showing ILS markers for 5000 and 6000 feet, if glidepath is usable at those higher altitudes
      • planes inbound secondary airports may enter at higher levels
    • v3.3.4:
      • press and hold 'cap' button to lower the skill value (reduce traffic), and holding it till 4.0 now closes the airspace
      • more accurate heading suggestions from planes near storms
      • adjusted altitude of inbound aircraft, so they enter not higher than the top of the airspace
      • text at the bottom of the screen shows the distance d from plane to cursor (PC)
      • planes to secondary airports now also reduce to speed 220KT automatically, and planes inbound JFK no longer fly inbound the LGA VOR to reduce confusion with traffic to KLGA.
      • adjusted headings after takeoff


    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)
    • extended ILS range: glidepaths useable up to 6000' at KATL, 5000' at EGLL
    • TTS speech queue improvements. Readbacks come before new calls; pilots will now less likely 'interrupt' you, as any new calls will wait a bit when a plane is selected (handy if you like to 'talk along' like a real ATCO while playing).
    • easier expediting climb by doubletapping in the middle between the altitude buttons
    • improved callsign pronunciation for Atlanta
    • 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 for heavies
    • automatic repositioning of labels for parallel approaching planes, to avoid label overlap
    • increased ILS range slightly
    • show line to departure beacon for better visibility

    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), restricted areas and multiple airports were added (Atlanta, London and Frankfurt).

          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.

              Delete
            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 :-)

            ReplyDelete
            Replies
            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.

              Delete
          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.

          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,

            Stelios

            (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.

            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.

            ReplyDelete

            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.

          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?

            Replies
            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).

              Delete
            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.

              M

              Delete
            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.

            Replies
            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.

              Delete
            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.

          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?

            ReplyDelete
            Replies
            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.

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

            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. 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.

              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.

              Delete
            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.

            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?

            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: alonsofer25@gmail.com

          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,
            http://stargear.web.fc2.com/products/eATC_jp.html

            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 !

            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.

              Delete
            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.

          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!

              Delete
            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!

              Delete
            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.

              Delete
            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!?

              Delete
            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."

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

          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?
