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 ...
A parachute airlock, often abbreviated to airlock, is a safety mechanism built into some parachute models which helps them resist losing their shape while open. It uses a ram air structure to stiffen each section of the outer edge. The design was first developed by parachute inventor Brian Germain following a near-fatal ram-air wing collapse in ...
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.
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 ...
For instance, if your car's value has dropped to $25,000 but you still owe $30,000 on your loan, gap insurance would cover that $5,000 difference if your car is totaled or stolen.

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.
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
