The ABC’s of Skydiving: G

Glide ratio – This is the ratio that refers to how much a parachute glides forward, as compared to flying down. For instance, a chute that has a 3:1 glide ratio will glide 3 feet forward for every 1 foot of gliding down towards the earth.

GPS – Global Positioning System. This is mostly used in skydiving aircraft so that the exit can be clearly marked.

Grips – This is when a diver hangs on to another diver for formation or in freefall attempts. A formation is not considered complete until all grips are in proper place.

Grippers – These specifically refer to group formation and are accessories placed onto jump suits so that gripping is made easier.

Ground speed – This refers to how fast a skydiver is moving over the ground, as opposed to through the air.
