What is the function of a personal flotation device (PFD)?

The function of a personal flotation device (PFD) is to keep the wearer afloat in water until rescue. PFDs are designed to provide buoyancy, reducing the risk of drowning and allowing individuals to remain on the surface of water. They are an essential safety tool for pilots and passengers in situations where immersion in water may occur, such as during an emergency water landing. The design of PFDs often includes features like adjustable straps, reflective materials for visibility, and some even provide extra insulation or additional survival aids for extended periods in the water.

Understanding the purpose of a PFD emphasizes the importance of water survival and readiness in aviation emergencies, reinforcing the necessity for aircrew members to be properly trained in the use of these devices.
