This was originally developed as a Camerapersons Harness for media personnel filming from helicopters. It was later modified to incorporate a 3-ring quick release into the rear attachment strap that is activated from a pillow handle at the front. (The 3-ring is widely used on sport parachutes to release the main parachute in an emergency.)
This S012 is popular with Air Dispatchers, Helicopter Winch Operators and others who, during flight, are close to an open hatch.
The S012 has been tested to Australian Standard AS 1891:1983 and approved by CASA under the provisions of CAR (1998) 21.305A. Application to an individual aircraft requires separate approval. Not approved for take off or landing.
