If a flight engineer has never served on a turbojet, what requirement must they fulfill before being assigned to a turbojet?

Before being assigned to a turbojet, a flight engineer must undergo initial training specifically tailored to turbojet operation. This initial training is essential because turbojet engines operate differently from other types of engines, such as piston or turboprop engines. The technology and systems associated with turbojets require a unique understanding of performance characteristics, handling, and maintenance procedures.

The training covers critical areas such as engine operation, control systems, and emergency procedures, ensuring that the flight engineer is well-versed in the specifics of turbojet aircraft. This knowledge is fundamental for operating safely and effectively in a turbojet environment.

While refresher training, flight instructor certification, and medical certification may be relevant for various operational roles, they do not specifically equip a flight engineer with the necessary knowledge and skills to work on turbojet engines. Hence, initial training is the crucial requirement for someone transitioning to this type of aircraft.
