APRON DEP

Apron Departure is used when the apron is split and one of these applies:
- B_GND — A_GND is online and C_GND is offline, or
- C_GND — B_GND and A_GND are both online.
Strip behaviour matches AA + AD in general, but this scope has a smaller set of bays and some columns are locked.
In STARTUP and PUSH BACK, strips do not display the next frequency below the callsign. SI ownership indicators and transfer actions are unchanged.
Select an owned aircraft’s callsign, then use TW, TE, GW, or GE in TWY DEP to change its next-controller SI target without starting a transfer. Click SI separately to initiate the handoff. The selection survives routing updates until ownership changes. The buttons retain their normal colors regardless of controller availability. If the target is offline, the existing SI value is unchanged; a blank SI stays blank.
Selecting K2, K3, A, F, D, B, V2, or V1 on the apron taxi map moves the strip to TWY DEP-LWR, regardless of other controllers being online. The existing K1 lower-bay routing is unchanged.

Using this scope
Section titled “Using this scope”Active bays (STAND, TWY ARR, De-ice) cover apron arrival and de-ice taxi movements. Locked columns are visible for situational awareness but are not manipulated here.
Use REQ only where the bay and strip type allow — locked bays do not offer REQ behaviour.
For full pushback → taxi → TWY DEP sequencing, see AA + AD or Apron Arrival. For clearance and PDC, see CLR DEL and Pre-departure clearance.
