CYPRES II panel. In skydiving, an automatic activation device (AAD) is a dead man's switch consisting of an electronic-pyrotechnic or mechanical device that automatically activates the opening sequence of the main or reserve parachute container when the AAD is falling below a preset altitude and above a preset descent speed.
Since a sport skydiver jumps with a main and a reserve parachute, it is possible for both parachutes to deploy. This often occurs when a skydiver employing an Automatic Activation Device (AAD) deploys the main canopy at an altitude low enough for the AAD to activate. This may result in a dangerous main-reserve entanglement.
