When must seatbelts be fastened in an aircraft?

The requirement for seatbelts to be fastened during movement on the surface, takeoff, and landing is rooted in safety protocols designed to protect passengers in critical phases of flight. These are the moments when an aircraft is most susceptible to sudden movements or unexpected events, such as changes in speed, altitude, or weather conditions. By ensuring that everyone is secured during these phases, the risk of injury is significantly minimized, as sudden stops or turbulence can throw unrestrained passengers around the cabin.

While some may think that seatbelts are only needed during turbulence or strictly during takeoff, the reality is that the most vulnerable times for an aircraft and its passengers are during the moments it is preparing to launch, is in the process of taking off, and when it is landing. Thus, the directive encompasses surface movements as well, since the aircraft can experience sudden jolts even while taxiing.

Maintaining seatbelt use during these critical stages enhances overall flight safety and aligns with the standard operating procedures mandated by aviation authorities.
