Basic instructions for the simulation game Endless ATC:
(updated: 6 July 2018)
|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:
- the ILS mode of the plane is activated,
- 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),
- the plane has to be descended low enough to intercept the glideslope; the blue circles mark the heights of 2000, 3000 and 4000 feet.
- 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:
- fly too close to eachother (in general: overlapping circles and altitude difference <1000 feet),
- divert (leave the airspace at the 30 nm boundary), also if they are departures but fly at or below FL100 when leaving the airspace,
- abort the approach (runway occupied, too high altitude etc.),
- are delayed (not landed within about 40 minutes)
- An aircraft label has the following lines of info:
- current altitude and selected altitude (in feet divided by 100),
- ground speed (in knots), weight category (medium, Heavy or Super J), mode (ils/direct/hold).
- 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:
- both planes are on a different ILS localizer ('LOC' status), so independent parallel approaches are possible,
- one or both planes are under the minimum altitude (1600 feet),
- two departures are on a divergent heading of 15 degrees or more,
- just after a go-around you'll get a short amount of time to regain a safe separation.
|Plane with destination 'RD'|
- 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.
- 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.
- The free version doesn't seem to run on some Huawei devices (with android 6); mail me for an alternative version.
- If you experience bugs or crashes, please send a crash report and/or mail me to look for a solution.

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 doubleclicking ILS
- 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 (PC), on android use second finger to show distance from selected plane
- after a long delay planes will divert automatically
- some minor adjustments and bugfixes
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
- 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
