Procedure



In the early days, a trained skydiver (or jumper) and a group of associates meet at an isolated airport, sometimes referred to as a "drop zone." A fixed base operator at that airport usually operates one or more aircraft, and takes groups of skydivers up for a fee. It was common for an individual jumper to go up in a Cessna light aircraft such as C-172 or C-185. These days, it is common for busier DZ's near populated areas to use multiple, larger aircraft such as the Cessna Caravan C208 or DeHavilland Twin Otter DHC6.
A typical jump involves individuals jumping out of an aircraft (usually an airplane, but sometimes a helicopter or even the gondola of a balloon), travelling at approximately 4,000 meters (around 13,000 feet) altitude, and free-falling for a period of time before activating a parachute to slow the landing down to safe speeds.
