In July 1995, the CORD Group of Nova Scotia conducted a ditched helicopter evacuation trial in calm water in the Bergen Fjord. The objective was to advise the National Energy Board of Canada of the preferred method of evacuation - dry versus wet and whether evacuation should be conducted on the windward or the leeward side of the helicopter. Dry and wet evacuations were conducted by 24 male and 19 female subjects from the Nutec Super Puma Simulator into two different types of aviation liferaft. Dry evacuation on the windward side is the method of choice. The non-canopy raft is subjectively and objectively easier to enter both from the helicopter and the sea. The canopy raft needs redesign to ensure that it always inflates the correct way and both rafts need a redesign to ensure that it always inflates the correct way and both rafts need a redesign of the painter anchor point. Aircrew should have special training in open water after traditional pool training. A helicopter ditching survival compass has been developed for training all who fly over water for a living.
