Why is it important for passengers to keep their seat belts fastened during an emergency landing?

Keeping seat belts fastened during an emergency landing is crucial primarily to minimize the risk of injury during turbulence or impact. In the event of an emergency, such as unexpected turbulence or a hard landing, passengers who have their seat belts fastened are better protected from being thrown around the cabin. Seat belts restrain the body, reducing the likelihood of serious injuries caused by sudden movements or collisions with other objects within the aircraft.

In addition, an unrestrained passenger can inadvertently become a projectile, posing risks not only to themselves but also to others around them. This practice enhances overall safety during potentially life-threatening situations, where abrupt changes in motion are common. Maintaining a secure seat belt helps to ensure that passengers remain in their seats, reducing chaos and facilitating a more controlled environment during an emergency.
