Main assisted reserve deployment (original) (raw)

A Main-Assisted Reserve Deployment (MARD) system is a skydiving safety device for parachute systems. While there are many variations, the operation and intended outcome for each is the same: open the reserve parachute container and extract the reserve parachute's deployment bag (and parachute) using the jettisoned main canopy. A MARD builds upon how a reserve static line (RSL) safety device works and in most circumstances, MARDs incorporate an RSL.
