2.2 Tandem CYPRES
The Tandem CYPRES can be recognized by the
blue button with the imprint „Tandem“ on the
control unit.
It activates the release unit when it detects a rate of
descent higher than approx. 78 mph (35 m/s) at an
altitude of approx. 1900 feet (approx. 580 meters)
above ground level.
Like the Expert CYPRES, the Tandem CYPRES
ceases operation below approx. 130 feet (approx.
40 meters) above ground level.
2.1 Expert CYPRES
The Expert CYPRES can be recognized by the red
button on the control unit.
It activates the release unit when it detects a rate
of descent higher than approx. 78 mph (35 m/s)
at an altitude of approx. 750 feet (approx. 225
meters) above ground level (AGL). In the event of
a cutaway CYPRES will operate down to approx.
130 feet above ground level. Below approx. 130
feet (approx. 40 meters) above ground level open-
ing is no longer useful. For this reason, CYPRES
ceases operation below approximately 130 feet
above ground level.
High speed at low altitude: If you exceed the vertical
speed of 78mph (35 m/s) at an altitude below 1000 feet
(300 meters) under your main canopy, then your Expert
CYPRES is designed to cut the reserve closing loop.
That can cause injury or death. Never do that.
For your information: 35 m/s is approximately
70% of freefall speed.
