Who typically uses the jumpseat in the flight deck?

The jumpseat in the flight deck is designed for individuals who are authorized to occupy it during a flight, primarily for operational and training purposes. This seat is typically used by pilots, including those who may be undergoing evaluation or training, such as check pilots, who can assess the flight crew's performance.

Additionally, FAA officials may use the jumpseat as part of their oversight responsibilities to ensure compliance with safety regulations and procedures during actual flight operations. This facilitates real-world observation of crew activities and adherence to aircraft protocols.

Other categories of personnel, like cabin crew members, may utilize jumpseats in the cabin area during takeoff and landing, but not in the flight deck. Consequently, the usage of the jumpseat by pilots, check pilots, and FAA officials reflects established practices in aviation safety and training, making this the correct choice.
