What is the purpose of the Parachute Harness Sensing Release Unit?

• A. It triggers automatic parachute release when altitude is reached
• B. Sea Water activated release system that provides a back up automatic mode of separating the parachute from the aircrew
• C. It seals the parachute during high wind
• D. It manually releases the parachute with a handle

Answer: (B)

This device is designed to automatically separate the parachute from the aircrew when it comes into contact with seawater, acting as a backup automatic release. In a water egress, you want the harness and canopy to detach so the aircrew isn’t dragged or entangled, allowing safer swimming and easier rescue if the pilot can’t reach a manual release. The key point is sea-water activation providing an automatic mode, supplementing the manual release that can be used when the aircrew is able to operate it. It’s not about releasing at altitude, sealing the canopy, or a manual handle action.
