In single-engine fixed wing aircraft, who is required to wear an inflatable PFD?

In single-engine fixed-wing aircraft, it is a requirement for all occupants to wear an inflatable personal flotation device (PFD) when operating beyond power-off gliding distance from shore. This requirement is in place to enhance safety in the event of an emergency water landing. Since a single-engine aircraft's ability to glide may be limited, especially if the engine fails, being within gliding distance of a safe landing area is essential.

By mandating PFD use beyond this distance, the regulation aims to ensure that all individuals aboard are prepared for a potential ditching scenario, providing them with necessary flotation assistance should they find themselves in the water. Occupants closer to shore may have alternative means of egress or rescue, but those further away are at greater risk and thus must be equipped with the proper safety gear. This proactive safety measure is vital for ensuring occupant survival in emergencies.
