'''Cypres''' is an acronym for '''Cy'''bernetic '''P'''arachute '''Re'''lease '''S'''ystem. It refers to a specific make and model of an [[Automatic Activation Device]] (AAD), a device that automatically opens a [[parachute]] (typically as a reserve system for a skydiver) under certain circumstances. A Cypres will usually open at a preset altitude if the rate of descent is over a certain threshold. The manufacturer of the Cypres is Airtec. The Cypres works by using a cutter to cut the [[reserve container]] [[closing loop]]. A spring loaded [[pilot chute]] then leaves the container and breaks through the skydiver's slipstream to begin reserve deployment. The Cypres comes in four different models: Expert, Student, Tandem and Speed. The basic operation of the units is the same; only the activation parameters are different, having been optimized for different types of skydiving. The name Cypres may be a pun on the legal phrase "[[Cy-près doctrine|cy pres]]," which is translated "as near as possible." == External links == * [http://www.cypres.cc Airtec website] * [http://www.cypres-usa.com Cypres device website] * [http://www.cypres-2.com Cypres 2 (newer model) device website] [[Category: Parachuting]] [[de:Cypres]] [[fr:Cypres]] {{industry-stub}}
