Who is responsible for preflighting the flight engineer oxygen equipment?

The responsibility for preflighting the flight engineer oxygen equipment lies specifically with the flight engineer before each flight. This requirement stems from the need to ensure that all safety equipment, including oxygen systems, is functioning properly and is ready for immediate use in case of an emergency. The flight engineer is tasked with conducting thorough checks on equipment that directly impacts the safety of operations, making it imperative that they verify the oxygen system's integrity and readiness.

While pilots and maintenance crews have significant roles in preflight checks and overall aircraft safety, the direct responsibility for the flight engineer's oxygen equipment specifically falls to the flight engineer. This individual is trained to handle and assess the functionality of the equipment they will use during the flight, ensuring that it meets required safety standards before departure. Proper preflight checks not only enhance flight safety but also prepare the flight engineer for any scenario requiring the use of supplemental oxygen.
