Under what conditions should pilots and flight attendants wear their shoulder harness?

Pilots and flight attendants are required to wear their shoulder harness during takeoff, landing, and periods of turbulence to ensure their safety and mitigate the risks associated with these critical phases of flight. Takeoff and landing are the phases when the aircraft is most vulnerable to incidents, and wearing a shoulder harness provides additional protection by restraining the individual in their seat in the event of sudden deceleration or other unexpected movements.

Turbulence can occur unexpectedly and can be severe enough to cause injury to crew members not properly secured. Wearing a shoulder harness helps to keep crew members safely in their seats, allowing them to maintain control of the aircraft or assist passengers without the risk of being thrown around the cabin.

This practice aligns with safety regulations and established procedures aimed at minimizing injuries and ensuring the well-being of both the crew and passengers during these crucial operational phases. Therefore, it is essential that both pilots and flight attendants adhere to this requirement to enhance safety in the flight environment.
