power-back

power-back

An expression used to indicate the rearward taxi of an aircraft on the surface of an aerodrome. If ATC (air traffic control) is not in a position to see all the obstructions that an aircraft might encounter during a power-back, then when the pilot requests a power-back, ATC will respond, “Power back at your discretion.” ATC will give the pilot as much traffic information as possible. Also called push-back.
