2.3 Student CYPRES
The Student CYPRES can be recognized by the
yellow button with the imprint „Student“ on the
control unit.
It activates the release unit when it detects a rate
of descent higher than approx. 29 mph (13 m/s).
The activation altitude is split. In the case of rate of
descent being approx. that of free fall, the opening
altitude is at approx. 750 feet (the same as with Ex-
pert CYPRES). However, should the rate of descent
be lower than that of freefall but still above the limit
of 29 mph (e.g. with partially opened canopy, or
after a cutaway), then Student CYPRES activates
the release unit when the altitude falls below approx.
1000 feet (approx. 300 meters) above ground level.
The student will then have more time to prepare
for landing. If under an open canopy, between
approximately 2700 ft and approximately 1000 ft
(approximately 800 meters and approximately 300
meters), the vertical speed is between approximately
7 mph and approximately 30 mph (approximately
3 m/s and approximately 13m/s) for more than 10
seconds, then the unit switches activation speed
from approx. 30 mph to approx. 45 mph (13 m/s to
20 m/s). This should reduce a possible activation
under open canopy. The Student CYPRES ceases
operation below approx. 130 feet (approx. 40 me-
ters) above ground level.
Unlike the Expert and Tandem CYPRES models, we
recommend that the Student CYPRES be switched
off in the aircraft prior to descent if the jump is
aborted and the student will land with the plane,
because the aircrafts vertical speed will exceed the
unit’s activation speed.
Activation on board: If a jump plane descends, switch
the Student CYPRES off above 1500 ft (450 meters)
above ground, or descend less than 1500 ft/min below
1500 feet above ground level. Close open doors.
Vertical Speed:
It is possible to exceed a vertical
speed of 29 mph (13 m/s) under a fully inflated canopy!
Avoid it. It can cause injury or death.
