The Flightline Expediter's primary duty is:

• A. Driving a radio-equipped car to communicate and manage the daily flying schedule
• B. Performing heavy maintenance in the hangar
• C. Directing inspections on a continuous basis
• D. Repairing aircraft in the field

Answer: (A)

On the flightline, keeping the daily flying schedule moving relies on clear, coordinated communication among pilots, crews, and support personnel. The Flightline Expediter acts as the on-ground dispatcher, driving a radio-equipped car to talk with everyone involved and to manage the sequence of departures, arrivals, and turnaround tasks. This role centers on coordinating the flow of operations and relaying timely updates so flights stay on schedule.

The other activities described belong to different responsibilities: performing heavy maintenance in the hangar is maintenance work, directing inspections is part of quality control or inspection duties, and repairing aircraft in the field is field maintenance or repair work. None of those emphasize the expediter’s primary function, which is facilitating communication and scheduling on the flightline.
