With certain exceptions, safety belts are required to be secured about passengers during

• A. Taxi, takeoffs and landings
• B. All phases of flight
• C. Only during cruise
• D. Only during turbulence

Answer: (A)

Keeping safety belts fastened during ground movement and the most dynamic flight phases is about protecting occupants when sudden movements are most likely. On the ground, engines, tow or taxi operations, braking, and possible misjudgments can toss you forward or sideways if you’re not restrained. In the air, takeoffs and landings involve rapid changes in speed and attitude, so being belted helps prevent injuries from abrupt acceleration, deceleration, or contact with internal surfaces.

There are exceptions. The crew may allow unbuckling temporarily when a task requires it or when the pilot determines it’s safe to do so. This makes the belt requirement specifically tied to the high-risk moments: taxi, takeoff, and landing, rather than every moment of flight or only during turbulence. That’s why the best answer is the one describing the belt being secured during taxi, takeoffs, and landings.
