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.

Caution

RWY ARR holds ARR-LOCKED strips in a locked bay here — not the TWY-ARR REQ strip used in AA + AD and Apron Arrival. Push back is also locked; there is no separate TWY DEP or Startup column in this scope.

Bay overview

Bay	Strip type	Notes

RWY ARR	Arrival locked (ARR-LOCKED)	Locked — not the same strip as RWY ARR in AA+AD / Apron Arrival.
STAND	APN-ARR	Active.
TWY ARR	APN-ARR	Apron arrival taxi; active.
De-ice	APN-TAXI-DEP	Active — taxi / de-ice routing.

Norwegian	Uncleared	Same as SAS.
Others	Uncleared	Same family as CLR DEL.

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.
