Who is responsible for the aircraft when a trainee is assigned to you during preflight preparation?

The Plane Captain holds primary responsibility for the aircraft during the preflight preparation, especially when a trainee is assigned. This role encompasses overseeing the overall integrity and readiness of the aircraft. The Plane Captain ensures that all necessary checks are completed, that the aircraft is in compliance with safety protocols, and that all pre-flight procedures are properly conducted.

Having a trainee assigned to them means that the Plane Captain must not only guide the trainee through these procedures but also maintain a focus on safety and ensure that all tasks are executed correctly. This responsibility includes verifying that the aircraft is safe for flight, ensuring that all required maintenance and safety checks are completed, and supervising the trainee to ensure they are gaining the necessary experience and knowledge under correct guidance.

In contrast, other roles such as the Flight Engineer or Aircraft Maintenance Technician may focus on specific technical aspects or repairs but do not carry the same overarching responsibility for the aircraft during preflight operations. The Safety Officer's role typically involves ensuring compliance with safety standards but does not include direct responsibility for the aircraft itself.
