Tracking (skydiving)
Tracking is a technique used by skydivers during freefall to increase their horizontal speed. Tracking is considered a fundamental skill in the sport because it allows multiple skydivers to gain separation from each other prior to deploying their parachutes. Nearly all licensing organizations mandate a student show proficiency at tracking in order to obtain their skydiving license. Technique Although there are many variations of the basic body position it essentially involves the skydiver moving out of the traditional face-to-earth & arched position, and straightening the legs, bringing the arms to the sides and de-arching, using the body to cup the air as a means of providing greater lift. There is debate over what exactly constitutes the most efficient tracking position (providing the best glide ratio) especially concerning how far (if at all) the skydiver's legs should be spread. Some variations of the tracking position work well for some individuals and not so well for othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skydiver
Parachuting and skydiving are methods of descending from a high point in an atmosphere to the ground or ocean surface with the aid of gravity, involving the control of speed during the descent using a parachute or multiple parachutes. For human skydiving, there is often a phase of free fall (the skydiving segment), where the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. In cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the lower atmosphere of Earth, or it may be significantly delayed. For example, in a planetary atmosphere, where an object is descending "under parachute" following atmospheric entry from space, may occur only after the hypersonic entry phase and initial deceleration that occurs due to friction with the thin upper atmosphere. History The first parachute jump in history was made on 22 October 1797 by Frenchman André-Jacques Garnerin above Parc Monceau, Paris. He ...
