Like many extreme sports, skydiving comes with its own lexicon of technical and slang terms that can be confusing to beginners. That’s why we’ve compiled this skydiving glossary of terms to help you feel at home when you’re learning how to jump.
No skydiving glossary of terms can be 100% complete as, like any language, the skydiving vocabulary is constantly changing. But these basics should cover everything you need to know, and if you’re ever unsure what something means, then just ask. It’s always better to know so you can focus on the jump….
Skydiving glossary of terms
Below you’ll find a detailed skydiving glossary of terms. Including definitions of skydive slang, parachuting lingo & technical skydive terms to help you learn your bridle from burble.

Holes in the ribs of a cell that allow air to flow through.
Having jumped recently.
Essential in any skydiving glossary of terms, cutting away is a standard emergency procedure prior to deploying the reserve. Also known as a breakaway.
Canopy relative work involves flying with parachutes in close formation, sometimes holding other chutes in mid air
When you flatten out or reverse one’s body position from the normal arched box man
Every parachute carries a data card with information on the reserve parachute, including all relevant details.
The altitude at which a skydiver is trained to begin execution of emergency procedures.
The parts of the parachute that control deployment of the canopy.
Loops on the front risers that make it easy to grip for steering purposes. Also called front riser loops.
Common term for a skydiving centre.

A method of setting brakes in the desired position for the parachutes deployment.
Pulling down the brakes of the canopy in order to slow it down, resulting in a reduced descent rate.
Skydivers who leave the airplane before base are called floaters as they use a slow fall rate.
This occurs when one or more skydivers gets themselves in an unstable body position.
The distance a canopy flies forward compared to downwards movement.
Using hands to hold onto other skydivers in freefall or during aircraft exits.
Holds built into formation skydiving jumpsuits.

To activate the parachute manually deploying the pilot chute.
The direction the aircraft, skydiver or parachute is facing.
Flying directly into the ambient wind.

A turn of 90-degrees or more executed close to the ground.
When the airplane does not shut down during fueling.
A reserve packed within the previous 120 days is said to be ‘in date’.

A jumpmaster has all of the privileges of an instructor except that they cannot supervise a first jump course, sign off licenses, or manage a student programme.
A signal to move on to the next step in a skydive.
Line of flight
An imaginary line corresponding to the jump plane’s path over the ground.
A log of activity and achievements in order to document experience.
The mean sea level is used by pilots when defining altitude.
A list of skydivers in the plane
Landing off target.
1) The skydiver who first gets to the base. 2) The act of docking on the base. 3) The closing pin of the home or reserve container.
A small, round parachute that acts to extract the parachute from the container and deploy it.
A parachute landing fall is a technique used to minimize injury during rough landings.
The review of a skydive after everyone has landed. A skydiving glossary of terms should come in handy here.
A hand deployed pilot chute packed inside the container and pulled out using a handle.
Pull up cord
A piece of cord used to pull the closing loop through the grommets of the container.
The reserve static line is a line from the home risers to the reserve cable.
The apparent wind felt by a jumper in freefall.
The auxiliary parachute carried on every jump.
The deployment system on all reserves and most student parachutes.

Someone qualified to be pack parachute rigs.
The certificate possessed by a rigger as proof of qualifications.
The webbing that connects the harness to the suspension lines.
A formation where each skydiver grips the arms of those next to him, also known as a star.
When a canopy is flying with the ambient wind.
Safety and training advisor.
The skydiver’s information manual.
A single operation system which simplifies emergency procedures by combining the functions of the cut away and reserve handle.

The vertical strips of cloth attached to the end cells of the canopy improving your ability to fly straight.
When the angle of attack becomes too high to sustain lift, the wing is stalled.
When the parachute deployment system is attached to the airplane with a cord, resulting in deployment immediately after exit.

Handles attached to the end of the steering lines to facilitate their use.
A type of freefall competition where an individual skydiver attempts to execute moves in a specified time period.
The lines from the risers to the canopy.
1) Diving down to a formation or individual in freefall. 2) To aggressively approach the landing area in order to produce a flat and exciting landing.Detailed skydiving glossary of terms. Definitions of skydive slang, parachuting lingo & technical skydive terms to help you learn your bridle from burble.
Parachute jumps in which two skydivers, usually an instructor and student, share one parachute.
