What should be done with seat belts during an emergency landing according to the SOS protocol?

The proper procedure during an emergency landing, as outlined by protocols such as SOS, is to keep seat belts fastened until instructed otherwise. This precaution is essential for several reasons.

During an emergency landing, there can be unexpected movements or impacts that could pose additional hazards to passengers. Keeping seat belts fastened ensures that individuals remain safely in their seats, reducing the risk of injury from sudden jolts or collisions while the aircraft is landing or coming to a stop.

Additionally, only after the aircraft has come to a complete stop and the crew has assessed the situation can clear and safe conditions be met for unbuckling. It is crucial for the cabin crew to maintain order and ensure the safety of all passengers during this critical time, which is why they will provide instructions on when it is safe to unbuckle.

Maintaining a disciplined approach helps facilitate a more orderly evacuation process, should it become necessary, and minimizes the chaos in the cabin. Thus, the correct action is to keep seat belts fastened until further instruction is given.
