The PSP™ is an integrated seat-life raft survival kit configured for rotor wing use. The PSP™ system has been designed to offer crewmembers an accessible liferaft & survival kit for easy egress of a helicopter during emergency over-water evacuation. The PSP™ system configurations are lightweight, low profile containers, contoured to fit in the backrest of the crew seat.

The Cushion Insert personal survival pack (PSP) is a removable part of the crew seat cushion with fabric handles for removal from the seat. The pack is secured to the seat back cushion by means of Velcro straps, and has a separate adjustable lumbar support. The liferaft is deployed after egress from the helicopter by pulling a lanyard which activates the CO2 system to inflate the raft.
