Helicopter Underwater Escape Training

This theoretical component specifically outlines the three phases[12] of a ditching (pre-impact, post-impact, and rescue) to ensure that individuals can complete tasks that will improve survivability.

Pre-impact tasks include aspects of being physically and mentally prepared for the flight (e.g., adequate sleep, proper hydration and caloric intake, and dressing appropriately for the expected environmental conditions[13]).

The program identifies immediate actions (e.g., securing losses articles within close proximity, tightening of seat restrains including stowage of excess material, identification of primary and secondary exits, and brace positions[14][15]) to be taken in the event of an in-flight emergency that requires the pilots to make a ditching.

Priority is placed on the development of an appropriate brace position, as reports have identified that drowning is the most prevalent cause of death during a ditching;[16][17] however, the pre-impact phase includes the preparation prior to arrival at a heliport and ends the moment that the helicopter touches the surface of the water.

[22] Once an exit has been removed,[23] a hand should be placed on the open window/door edge to ensure that when the seat restrain is released, there is a physical reference point directly to the outside of the fuselage.

In-water survival instruction most often covers aspects of PPE such as life jackets, immersion suits,[28] and signalling devices as well as the effects of hypothermia.
