10. Automatic Ripcord Release AR2. The AR2 is designed to open the main or reserve parachute compartment automatically. The AR2 consists of an aneroid with associated mechanism, rate-of-fall sensing chamber, and a spring-loaded power cable. All components except the power cable and its flexible conduit are contained in a housing. The housing provides all required chamber, passages and mounting pads for each component. An altitude setting dial and JUMP/OFF switch are mounted on the housing. There are two power cables assemblies, one for opening the main parachute and one for opening the reserve parachute. The power cable ends in a fixed eye that connects to the parachute ripcord pin. A lanyard assembly with cap is attached to the power cable to protect the open end of the power housing when detached from the AR2. Refer to TM 10-1670-305-23&P for operational limitations, maintenance, and repair.

11. Reserve Parachute Assembly. The reserve parachute consists of a seven-cell ram air canopy and the reserve deployment system. The canopy is attached to the reserve risers and is packed in the upper compartment of the container. The reserve parachute can be deployed by three methods: manually by using the reserve ripcord, by the reserve static line upon release of the main parachute after pulling the main canopy release ripcord, or by actuation of the reserve mounted AAD.
