RAPS evolved into the category system, which allows students to use ram-air canopies from their first jump. In the early jumps the parachute is deployed automatically using a static line; after proving basic proficiency the student progresses onto freefall, opening their own parachute by means of a ripcord and spring-loaded pilot chute. The ...
The RA-1 Military Free-Fall Advanced Ram-Air Parachute System (MFF ARAPS) provides a multi-mission, high-altitude parachute delivery system that allows personnel to exit at altitudes between 3,500 feet and 35,000 feet. The parachute, which replaces the current MC-4 parachute, supports a total jumper weight of 450 pounds.
Overly rapid deployment was an early problem with ram-air designs. The primary innovation that slows the deployment of a ram-air canopy is the slider; a small rectangular piece of fabric with a grommet near each corner. Four collections of lines go through the grommets to the risers (risers are strips of webbing joining the harness and the ...
The parachute is a seven-celled MT1-X, the first ram-air parachute to be adopted by the U.S. Military as the standard freefall canopy. The wings represent flight and airborne capabilities. Free-fall training
Ram air refers to the principle of using the airflow created by a moving object to increase ambient pressure, known as ram pressure. Often, the purpose of a ram air system is to increase an engine's power. The term "ram air" may also refer to: Parafoils, also called ram air parachutes, non-rigid airfoils inflated by wind

The static line and D-Bag stay with the aircraft as the jumper leaves, and are pulled back into the aircraft by the dispatcher. Now free of its D-Bag, the canopy is allowed to inflate as the jumper continues to fall. Effectively, the jumper drags the parachute behind him, causing the upward-rushing wind to force open and inflate the canopy.
A slider is a small rectangular piece of fabric with a grommet near each corner used to control the deployment of a "ram-air" parachute. Also called a "reefing device." [2] A ram-air parachute has a tendency to open very rapidly. At high velocities, the opening shock from a rapid deployment can cause damage to the canopy or injury to the jumper.
