Aviation Standard Test Battery-E (ASTB E) Practice Test

The flight deck is primarily managed by the flight crews, which include pilots and co-pilots. They are responsible for operating the aircraft, making real-time decisions during flight, and ensuring the safety of the passengers and crew. Plane directors, on the other hand, are typically ground personnel who provide guidance to pilots during taxi operations on the ground rather than on the flight deck itself.

The role of maintenance personnel is focused on performing inspections and repairs, while cargo handlers deal primarily with loading and unloading cargo rather than aircraft operation. Therefore, the most accurate answer regarding who handles aircraft on the flight deck is the flight crews, as they are directly involved in the operation and management of the aircraft during all phases of flight.
