What is the recommended procedure for the use of emergency flotation devices?

The recommended procedure for the use of emergency flotation devices is to inflate them upon immersion in water. This approach is crucial because it ensures that the flotation devices are activated at the most critical moment when they are needed for buoyancy and support. Deploying the devices at the point of immersion maximizes their effectiveness, helping to keep individuals afloat and safe until they can be rescued.

Activating flotation devices after leaving the aircraft would not be practical, as there may not be sufficient time to do so before entering the water. Storing them under passenger seats is often a common practice; however, this does not address the procedure for their use in an emergency. Deploying them before takeoff does not align with safety protocols, as the devices should only be activated when necessary to avoid unnecessary deployment during the flight.
