Whenever a Flight Deck observer seat is not occupied, the seat belts and shoulder straps ______ be secured.

• A. must be secured
• B. should be secured
• C. may be secured
• D. need not be secured

Answer: (A)

The key idea is that safety equipment on the flight deck is treated as mandatory to keep the crew and cockpit area secure, even when a seat isn’t in use. When the Flight Deck observer seat is unoccupied, the seat belt and shoulder harness should be secured because an unsecured belt can move, snag on controls, or bounce around during turbulence or abrupt maneuvers. Securing them ensures the belt is in place and ready for immediate use if the seat becomes occupied, and it eliminates loose straps that could interfere with operations or become a hazard. This is a definite, non-negotiable safety practice, not merely a recommendation or optional action.
