Enter the original ACID into the remarks section of the flight plan. NOTE-
Use caution not to modify or delete any existing remarks.
Do not use the “Q” prefix (phonetic “Quebec”) when communicating with the aircraft.
Unless otherwise specified in a Standard Operating Procedure, verbally coordinate the aircraft's actual ACID when conducting intrafacility transfers of control.
Verbally coordinate the aircraft's actual ACID when conducting interfacility transfers of control. NOTE-
ATC personnel providing control services using ATOP automation systems are NOT required to amend ACIDs beginning with a number.
