This page describes text commands which can be sent to the airplane.

ATC switch commands

Hang off the airplane

Syntax:

{callsign} CC|CT

Meaning:

Block	Meaning	Description
CC	Contact Center ATC	Switch the radio frequency to the Center ATC.
CT	Contact Tower ATC	Switch the radio frequency to the Tower ATC.

These commands are meaningful only when the airplane has been accepted by the target ATC (see communication with the ATCs).

Accepting airplane

Syntax:

 {callsign} RC

Block	Meaning	Description
RC	Radar contact	Confirming that you have the visual contact with the airplane on the radar.

Airplane basic controlling commands

These commands control airplane altitude, speed, and heading.

Heading adjustment

These commands set the airplane heading.

Syntax:

{callsign} TL|TR|FH <hdg>

Block	Meaning	Description
TL	Turn left	Turns only left to the direction (even if the angle is over 180°
TR	Turn right	Turns only right to the direction (even if the angle is over 180°
FH	Fly heading	Turns to the requested direction using the closest angle

Variable	Meaning
hdg	Target heading, integer value between 0 and 359, represented by one to 3 digit number

Example:

EZY5495 TL 200

Altitude adjustment

These commands set the airplane altitude.

Syntax:

{callsign} CM|DM <alt>
{callsign} AC

Block	Meaning	Description
CM	Climb and maintain	Climb to the specified altitude
DM	Descend and maintain	Descend to the specified altitude
AC	Altitude restriction cancel	This command is used when there is some altitude restriction on SID/STAR/transition restricting airplane's climb/descend. After this command, all the restrictions placed over the route will be ignored.

Variable	Meaning
alt	Target altitude, in hundred feets, e.g., "20" means 2000ft, "70" means 7000ft or FL70

Example:

EZY5495 CM 200

Speed adjustment

These commands set the airplane speed or resumes airplane custom speed.

Syntax:

{callsign} SL|SM|SE <speed>
{callsign} SC

Block	Meaning	Description
SL	Speed less than ...	Orders speed less or equal to the specified
SM	Speed more than ...	Orders speed more or equal to the specified
SE	Speed exactly ...	Orders speed equal to the specified
SC	Cancel speed restriction	Cancels previously ordered speed restriction

Variable	Meaning
spd	Target speed in kts, should be in the range allowed by the aircraft type, or the command will be refused

Example:

EZY5495 SL 200
EZY5495 SC

Conditional and sequence commands

After altitude ...

These commands says that the following command will be processed when the plane will pass the specified altitude.

Syntax:

{callsign} AA <alt>
{callsign} AA <alt>+|-

Block	Meaning	Description
AA	After altitude ...	Forces following commands are executed when exactly the specified altitude is being passed
+	... or above	The following commands are executed when the airplane is at the specified altitude or above
-	... or below	The following commands are executed when the airplane is at the specified altitude or below

Variable	Meaning
alt	Target altitude, in hundred feets, e.g., "20" means 2000ft, "70" means 7000ft or FL70

Example:

EZY5495 AA 40+ PD NASKI      // after altitude 4000ft or above proceed direct to NASKI

Routing supporting commands

Following commands should be used only in SID/STAR/transition route specifications and should not be ordered to an airplane directly.
