During which phases of flight must seat belts always be fastened?

The correct choice indicates that seat belts must always be fastened during movement on the surface, takeoff, and landing. This requirement is based on safety protocols designed to protect passengers and crew during the potentially turbulent and high-risk phases of flight.

When an aircraft is moving on the ground—whether it’s taxiing on the runway or being towed—there is a risk of sudden stops, sharp turns, or collisions, which necessitates that seat belts are secured to prevent injury. During takeoff, the aircraft experiences rapid acceleration and changes in speed, making it essential for passengers to be seatbelted to avoid being thrown around. Finally, landing presents its own set of risks, including abrupt deceleration, which can be hazardous for unrestrained individuals.

By requiring seat belts to be fastened throughout these phases, airlines aim to minimize the risk of injuries and enhance overall flight safety for everyone aboard.
