Skydivers can reach over 100 mph during free fall, which lasts roughly 45-60 seconds before a parachute is pulled, according to the USPA. Show comments Advertisement
The boards used are generally smaller than actual surfboards, and look more like snowboards or large skateboards. Custom bindings attach the board to the feet, which is removable with the use of a 2-ring release system based on the common 3-ring release system used to cut away main parachutes.

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.
A ripcord is a part of a skydiving harness-container system; a handle attached to a steel cable ending in a closing pin. The pin keeps the container closed and keeps the spring-loaded pilot chute inside. When the ripcord is pulled, the container is opened and the pilot chute is released, opening the parachute.
The closing pin passes through the closing loop [3] and in doing so, secures the main container of a skydiving rig, keeping the parachute from deploying prematurely. [4] When the pilot chute is thrown out by the skydiver and catches air, it pulls the closing pin from the closing loop and allows the main parachute to be released from the ...
In the early days of BASE jumping, people used modified skydiving gear, such as by removing the deployment bag and slider, stowing the lines in a tail pocket, and fitting a large pilot chute. However, modified skydiving gear is then prone to kinds of malfunction that are rare in normal skydiving (such as "line-overs" and broken lines).
Good trackers can cover nearly as much ground as the distance they fall, approaching a glide ratio of 1:1. The fall rate of a skydiver in an efficient track is significantly lower than that of one falling in a traditional face-to-earth position; the former reaching speeds as low as 40 metres per second (90 mph), the latter averaging around the 54 m/s (120 mph) mark.
Releasing the cord loop by removing the cable with a tug causes the three-ring system to cascade free and quickly disconnect the riser from the harness. Each ring in the series multiplies the mechanical advantage [ 3 ] of the loop of cord that is held in place by the semi-rigid cable (a Lolon-F or Teflon impregnated plastic coated steel cable ...
