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 reserve static line, occasionally called a Stevens Lanyard or Stevens Release, is a device that automatically opens the reserve parachute container when the main parachute is cut-away. The RSL is a lanyard connecting one or both of the main parachute risers to the reserve ripcord .
A pilot chute is a small auxiliary parachute used to deploy the main or reserve parachute. The pilot chute is connected by a bridle to the deployment bag containing the parachute. Pilot chutes are a critical component of all modern skydiving and BASE jumping gear. Pilot chutes are also used as a component of spacecraft such as NASA's Orion. [1]
In the unlikely event of a malfunction, students are taught how to cut away the main canopy and deploy the reserve chute. The aim of static line progression is to train students to maintain the correct, stable body position upon exiting the aircraft, and to teach how to deploy the canopy via the pilot chute mechanism.
Cut-away is a skydiving term referring to disconnecting the main parachute from the harness-container in case of a malfunction in preparation for opening the reserve parachute. The 3-ring release system on parachutes allows a rapid cut-away in the event of an emergency.
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 decent speed.
The Beaumont Reserve Fleet is one of only three remaining National Defense Reserve Fleets, of the original eight NDRFs, and the only anchorage on the Gulf Coast. The fleet is maintained by the Maritime Administration (MARAD), an agency of the Department of Transportation (DOT).
1 Main Circuit (1MC) is the term for the shipboard public address circuits on United States Navy and United States Coast Guard vessels.This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are (normally) able to hear it.
