What is required for flights beyond a certain distance from shore?

The requirement for having a life preserver or personal flotation device (PFD) for each person onboard during flights beyond a specified distance from shore is crucial for safety. When flying over water, particularly when far from land, there is an increased risk of needing to abandon the aircraft, either due to an emergency or an engine failure. Life preservers are essential because they enhance the chances of survival in the event of a water landing or ditching.

Regulations typically dictated by aviation authorities highlight the importance of having adequate flotation devices to ensure that all occupants can stay afloat until rescue. While other options such as extended weather briefings, secondary navigation methods, and backup engines are significant for ensuring flight safety more generally, having personal flotation devices is specifically mandated to address the unique risks associated with over-water flights. This safety measure directly addresses the potential dangers faced when operating away from the immediate safety of land.
