Altitudes are calculated in reference to either “ground level” or “sea level” but skydivers always use AGL when referring to jump altitude.Īirborne : A military force carried to the battlefield in gliders or by parachute from aircraft abbreviated “ABN”.Īirborne shuffle: A gliding walk, without lifting the feet, toward the exit of an aircraft in flight, when the JUMPMASTER directs the paratroopers to jump above the drop zone (DZ) this sliding gait is used to improve security and sustain balance on an unstable cargo DECK, and to avoid tripping or stumbling during the crucial interval between hookup and departure. An AFF student is trained in freefall techniques and landings by accompanied jumps with a qualified jumpmaster on actual descents lasting 20 to 40 seconds or longer, as opposed to static line training also known as “Accelerated Skydiving Program” (ASP).ĪGL : Above Ground Level.
#PROPER FREEFALL POSITION FREE#
A feat or stunt displaying a person’s skill, dexterity, or daring during aerial descent.ĪFF : Accelerated Free Fall, also called “harness hold” being one of the Instructor Assisted Deployment (IAD) techniques. A competitive event in which a skydiver performs a prearranged sequence of manoeuvres within a stipulated time period also known as freestyle or “style” competition.
#PROPER FREEFALL POSITION LICENSE#
A competitive event in which a skydiver attempts to land on (or as close to) an established target from a designated release point in the national competition, gradations are measured in centimetres.ĪDEPT : Alternate Door Exit Procedure for Training.Īerobatics: The skill manoeuvres essential for controlled aerial movement during a skydiver’s descent the mastery of which is required for Relative Work (RW), and a prerequisite for USPA license advancements. Parachutes and other airfoils are not classified as aircraft.Īccuracy: Accuracy landings of varying difficulty, from 20 meters to 2 meters, are required for USPA license advancements also known as “precision landing” or “precision jumping”. Also referred to as “jump plane” or “jump ship”.
A “fail-safe” device (eg: CYPRES, ASTRA, Sentinel, Irvin Height-Finder, FF-1, F1B) that senses the parachutist’s altitude and rate of descent, and is designed to mechanically activate the reserve parachute at graduated preset intervals of elapsed time, excess velocity, or minimum altitude, if the skydiver does not deactivate or disengage it during normal descent.Ī/C: The abbreviation for aircraft any machine or device, including aeroplanes, helicopters, gliders, dirigible, that’s capable of atmospheric flight. Please find below a comprehensive “Jargon” guide that covers a lot of commonly used skydiving terms universally used all over the globe.Įverything below is listed in Alphabetical order –ĪAD : Automatic Activation Device also known as Automatic Opening Device (AOD). Parachuting jargon can be quite confusing for the none skydiver.
