Emergency Exits for Underwater Escape from Rotorcraft

摘要

An experimental adjustable escape exit was used to determine the smallest rectangular exit compatible with underwater escape by passengers in the upper range of shoulder widths and wearing standard immersion protection. An exit 432 mm (17 in) x 356 mm (14 in) is considered to be the smallest acceptable size. Recommendations in respect to swimming goggles, hand-holds, and opening systems, and for a review of the advantages of a larger number of smaller escape exits for ditching emergencies are made.
