Flight crewmembers are required to keep their safety belts and shoulder harnesses fastened during which conditions?

• A. Safety belts during takeoff and landing and en route; Shoulder harnesses during takeoff and landing
• B. Only during turbulence
• C. Only on the ground
• D. At all times during flight

Answer: (A)

Restraints protect you from sudden aircraft motion. The lap belt must stay fastened whenever you’re seated for the entire flight, including en route portions, so you’re secured if turbulence or an unexpected maneuver occurs. The shoulder harness adds upper-torso restraint and is required to be fastened during takeoff and landing, when acceleration and deceleration forces are greatest. So the correct practice is to keep the safety belt fastened at all times while seated, and fasten the shoulder harness during takeoff and landing.
