flightline

A flightline is the area of an airfield where aircraft are parked, serviced, loaded, and prepared for flight.

It typically includes the apron or ramp space adjacent to hangars and maintenance facilities, distinct from runways and taxiways used for actual aircraft movement.

Military bases and commercial airports both use the term, though it's especially common in military aviation contexts.

Ground crews worked through the night on the flightline to ready the jets for the morning mission.
