Competitive accuracy landing is a team event with 5 persons on each team that takes place over 8 rounds. The team jumps together, generally from an altitude of 900 meters (3,000 feet), although sometimes as high as 1,100 meters (3,600 feet).
A parachute landing fall (PLF) is a safety technique that allows a parachutist to land safely and without injury. The technique is performed by paratroopers and recreational parachutists alike. The technique is used to displace the energy of the body contacting the earth at high speeds.
After inspiration from an article on slope soaring in the Parachute Manual magazine by parachutist and publisher Dan Poynter, [7] they calculated that on a suitable slope, a "square" ram-air parachute could be inflated by running down the slope; Bétemps launched from Pointe du Pertuiset, Mieussy, and flew 100 m.
The steerable parachute or parafoil is called a "decelerator," and gives the JPADS system directional control throughout its descent by means of decelerator steering lines attached to the Autonomous Guidance Unit (AGU). They create drag on either side of the decelerator, which turns the parachute, thus achieving directional control.
In June 1942, Adeline Grey was the first person to successfully test the human-rated parachute. This led to Pioneer becoming the world's leading manufacturer of parachutes, producing 300 per day at the height of WWII.

Some pilots carry a reserve parachute designed to open in as little as 50 ft (15 m). While reserve parachutes are designed to open fast, they have a system length between 13.3 ft (4.5 m) and 21.9 ft (7.3 m) [ 11 ] and usually need at least 150 ft (46 m) to slow down a pilot to a safe sink rate (certified design speed according to LTF and EN ...
