Shoulder harnesses must be fastened by flight crew members during which phases of flight?

Shoulder harnesses must be fastened by flight crew members during takeoff and landing to ensure safety during these critical phases of flight.

During takeoff, the aircraft is transitioning from the ground to the air, and any sudden maneuvers, turbulence, or unforeseen events can occur. Properly secured shoulder harnesses help protect crew members from injury in case of abrupt changes or emergency situations.

Similarly, during landing, the risk of difficulties increases as the aircraft approaches the ground. Securing shoulder harnesses enhances the safety of crew members, ensuring they are well-positioned and protected in case of hard landings or other unexpected circumstances.

While there are safety considerations during cruising and taxi, the regulations specifically emphasize the importance of harness use during these high-risk phases of flight. This focus on takeoff and landing serves to mitigate risks where accidents are statistically more likely to occur.
