Welcome to the ATC wiki!

Background

ATC stands for Air Traffic Controller, which is the role you take in this simulator.

Air traffic control (ATC) is a service provided by ground-based controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC worldwide is to prevent collisions, organize and expedite the flow of traffic, and provide information and other support for pilots. - Wikipedia


Command Reference

Although the tutorial gives a large amount of information, if you find remembering the commands too complicated, here's a reference. Remember that you can type out multiple commands in one go; for example: BAW231 fh090 d 30 sp 180 will work as well as all three commands run separately. Additionally, some have "shortKeys", where you can skip the space that is normally included, like in BAW231 fh090 (heading).

Taxi

Aliases - taxi / wait / w

Information - This command tells the specified plane to taxi to a runway; if a runway is not included they will continue to the runway with the largest headwind.

Syntax - AAL123 taxi [Runway]

SID

Aliases - sid

Information - This command tells the specified plane a standard instrument departure route (SID) it should follow. Each SID is a list of fixes to be flown in sequence. Having a standardized route often helps organize departing traffic, and maintain separation from arriving aircraft.

Syntax - AAL123 sid [SID name]

STAR

Aliases - star

Information - This command tells the plane to add or change their filed Standard Terminal Arrival Route to match the route you specify. This must be entered in dotted format, and include the point where the STAR is joined, as well as the destination airport, for example: MLP.GLASR9.KSEA. See the section on rerouting for further detail.

Syntax - AAL123 star [transition].[STAR name].[airport]

"Cleared As Filed"

Aliases - caf

Information - This command tells the airplane that they are cleared to follow the flight plan that they requested when spawning. Therefore, when a departure spawns on the ground, and his strip shows that he filed for a particular SID, there is no need to use the sid command. Just clear him "as filed" with the caf command, and the airplane will take care of the rest.

Syntax - AAL123 caf

"Climb Via SID"

Aliases - cvs

Information - Authorizes the aircraft to climb in accordance with the SID that is currently in their flightplan. They will climb to their filed cruise altitude, whilst complying with all altitude and speed restrictions posted in the procedure.

Syntax - AAL123 cvs

"Descend via STAR"

Aliases - dvs

Information - Authorizes the aircraft to descend in accordance with the SID that is currently in their flightplan. They will descend to the lowest altitude required by the STAR, and after no further altitude and/or speed restrictions are listed, will maintain their altitude and speed until receiving further instructions from ATC.

Syntax - AAL123 dvs

Altitude

Aliases - climb / c / descend / d / altitude / a

Hotkey - up arrow / down arrow (if "Control Method" setting = "Arrow Keys")

Information - This command tells the specified plane the altitude, in hundreds of feet (flight levels), it should travel to. This means that when writing altitudes you would drop the last two zeros. For example, 3,000ft = "30", 8,300ft = "83", 10,000ft = "100", and FL180 (18,000ft) = "180". Airplanes will not descend below 1000 feet (unless locked on ILS).

Syntax - AAL123 c [alt]

Takeoff

Aliases - takeoff, to, cto

Hotkey - numpad /

Information - This command clears the specified plane for takeoff. They will climb to the altitude specified, or in accordance with a SID if told previously to "climb via the SID". If neither has happened, they will ask for an altitude assignment before they agree to take off.

Syntax - AAL123 cto

Heading

Aliases - heading / h / turn / t

Shortkeys - fh / left arrow / right arrow (if "Control Method" setting = "Arrow Keys")

Information - This command sets the target heading; up (north) is 360, right (east) is 090, down (south) is 180, and left (west) is 270. Of course you can use any angle in between these as well. If the heading is set before takeoff, the aircraft will turn to that heading after takeoff. You can force the aircraft to reach the heading by turning left or right by inserting l or r before the new heading, as demonstrated below.

Syntax - AAL123 fh[hdg] or AAL123 (rightarrow)[hdg] or AAL123 t r [hdg]

Speed

Aliases - speed / slow / sp

ShortKey - numpad + / numpad -

Information - This command sets the target speed; aircraft will stay within their safe speeds if you tell them to fly faster or slower than they are able to. It takes some time to increase and reduce speed. Remember that speed is always expressed in knots.

Syntax - AAL123 -[spd] or AAL123 +[spd]

Land

Aliases - ils / i / land / l

Shortkey - numpad *

Information - This command clears the aircraft to land on a runway. The aircraft's strip on the right will show either "intercept" if it's still trying to intercept the localizer. Once established, it will show "on ILS" and the aircraft will automatically fly down the runway centerline, descend, and land.

Syntax - AAL123 i [rwy]

Reroute

Aliases - reroute, rr

Information - This command allows you to wipe out the aircraft's current route, and assign a new route of your choosing. This is similar to the route command, but this command will allow you to change the entire route, while the other is meant for specifying a route to follow to join a later point in the aircraft's flight plan. Note that the route uses dot format:

Note: Input data needs to be provided with single dots connecting all procedurally- linked points (eg KSFO.OFFSH9.SXC or SGD.V87.MOVER), and all other points that will be simply a fix direct to another fix need to be connected with double-dots (eg HLI..SQS..BERRA..JAN..KJAN).

Full Route Example: KSEA.HAROB5.ERAVE.Q1.ETCHY..MLBEC.BDEGA2.KSFO

Syntax - AAL123 rr [route]

Route

Aliases - route

Information - This command instructs aircraft to follow a user-provided "route", typically one that is along an airway, approach, SID, STAR, other published procedure, or a series of fixes. This is similar to the reroute/rr command, but this command will allow you to "insert" a route that connects with the route they're currently flying. Note that the route uses dot format:

Note: Input data needs to be provided with single dots connecting all procedurally-linked points (eg KSFO.OFFSH9.SXC or SGD.V87.MOVER), and all other points that will be simply a fix direct to another fix need to be connected with double-dots (eg HLI..SQS..BERRA..JAN..KJAN).

An example would be if an aircraft filed to take a particular airway, and you needed them to take a different one. Additionally, if the current route and the user-provided route share a common point, the routes are considered to have "continuity", and the FMS will remove the intermediate fixes. This is demonstrated below:
Current Route: BAM..CUTVA..LLC..FMG..BINNZ..HETUX..CHOIR..NEWPI..LKV.HAWKZ4.KSEA
Command run: AAL123 route FESKO..RUFUS..CHOIR
Resulting route: FESKO..RUFUS..CHOIR..NEWPI..LKV.HAWKZ4.KSEA

Thus, since the routes have continuity at CHOIR, we are able to give shortcuts and/or route extensions without needing to restate the whole route, as with the rr command. In the case of the above example, the aircraft would immediately turn direct to FESKO, join the specified route to CHOIR, and continue via last routing cleared.

Partial Route Example: WHITE.J209.ORF or FESKO..RUFUS..CHOIR or KSEA.MTN7.ELN..HAMUR.J12.DNJ

Syntax - AAL123 route [route]

Say Route

Aliases - sr

Information - With the capability to edit the route, you obviously will need a way to know what their current route is. Typically, this is displayed in the flight progress strip. However, to preserve screen space, you will instead have to check the route by running this command, and the route will print out above the command bar.

Syntax - AAL123 sr

Fix

Aliases - f / fix / track

Information - This command instructs the aircraft to fly direct to a fix or list of fixes before proceeding to the next point on their currently assigned route. This method is neither realistic nor preferred, thus, you should probably use the more powerful route or rr commands.

Syntax - AAL123 f [fixname]

"Proceed Direct"

Aliases - direct / pd / dct

Information - This command instructs the aircraft to go direct to a navigational fix, taking a shortcut. For example, if an aircraft is flying to fixes [A, B, C], issuing the command "pd B" will cause the aircraft to go to B, then C. After flying past the last fix, the aircraft will continue flying straight.

Syntax - AAL123 pd [fixname]

Abort

Aliases - abort

Information - Instructs the aircraft to abort the current operation. Currently, only landings, taxiing, and fix navigation can be aborted.

Syntax - AAL123 abort

Hold

Aliases - hold

Information - This command instructs the aircraft to enter a holding pattern until further notice. The direction (left/right) may be specified, as well as the leg length (in minutes), as well as the fix to hold over. But you may also omit those specifications, in which case, the aircraft will enter a standard holding pattern over their present position (right turns, 1 minute legs). To escape a hold, just set a new heading.

Parameters - Specify the direction of turns during the hold with right or left, the leg length, with [time]min, and the fix to hold over with simply [fixname]. Any combination of these arguments provided in any order is acceptable, as long as the command hold comes first.

Syntax - AAL123 hold [fixname] [left|right] [leg_time]min or AAL123 hold

Move Data Block

Aliases - ` (backtick)

Information - If aircraft data blocks are overlapping, it can be tough to tell which aircraft is which. And on real ATC systems, moving the data block is sometimes used by controllers to indicate the status of the aircraft, in reference to whether or not they have been told to do something yet (for instance, approach might move all the blocks down for a/c that have been switched to tower frequency). In this sim, you can shift it in any of the 8 subcardinal directions, in reference to their relative position on the numpad: (8:N, 9:NE, 6:E, 3:SE, 2:S, 1:SW, 4:W, 7:NW). Additionally, position 5 can be used to "shortstem" the aircraft, which puts the data block right on top of the aircraft's position symbol.

Syntax - AAL123 `2
