What condition should the galley trash chute flaps meet during a preflight check?

• A. Remain open for ventilation
• B. Spring loaded flap must close and seal
• C. Should be covered in a protective film
• D. Must have a warning label attached

Answer: (B)

During a preflight check, the galley trash chute flaps are crucial components that must function correctly to ensure safety and hygiene on board. The condition that the spring-loaded flap must close and seal is vital because this prevents unpleasant odors, pests, and contamination within the galley area. A proper seal ensures that any waste or debris contained within the chute does not escape into the cabin or galley, maintaining a clean and safe environment for both crew and passengers.

While maintaining ventilation is important, the primary function of the flap is to seal the rubbish chute to prevent any cross-contamination. Similarly, while protective films and warning labels may be relevant to other components, they do not have the same critical safety implication as the operational integrity of the flap. Ensuring that the flap closes and seals effectively supports overall aircraft safety procedures and hygiene management, which is essential in the restricted space of an aircraft galley.
