The B-20 Parachute Assembly is a basic non-automatic back style parachute. The B-20 consists of a standard C-9 canopy, risers, pilot parachute assembly, cushion, harness and pack assembly (which incorporates a D-Handle ripcord grip) and two PCU-4/P canopy releases.
The B-20 has an operational capability of less than 25,000 feet and 300 knots of air speed. The B-20 Parachute Assembly is designed for use in non-ejection seat type aircraft, such as C-46, C-54, C-117, C-130, and H-21.
Following egress from the aircraft, the aircrewman manually pulls the ripcord assembly to initiate canopy inflation.
