8.1 Important notes for jump pilots
• A Student, Expert, Speed or Wingsuit CYPRES
will not work if the aircraft is exited before it
reaches 1500 feet (450m) above the aireld
takeoff elevation and 1500 feet (450m) above
the intended dropzone elevation. In the case
of a Tandem CYPRES 3000 feet (900m) has
to be reached.
• After take off please ascend at more than 180
feet per minute (1 meter per second) for at least
30 seconds.
• Never descend to an altitude below the aireld
takeoff elevation.
• If CYPRES has been adjusted to a dropzone
elevation above aireld takeoff elevation and
the aircraft has climbed above the intended
dropzone elevation, it must not descend below
the intended dropzone elevation again.
• If CYPRES has been adjusted to a drop zone
elevation altitude below the aireld takeoff
elevation, the aircraft must not descend below
the intended dropzone elevation.
A simple rule: Never descend below the elevation
of the takeoff aireld or the intended DZ!
• When using an aircraft capable of pressuriza-
tion, make sure that the cabin remains open
when the turbines are started up. Leave a
window, a door, or the ramp open a bit until
after lift-off. It has to be ensured that the cabin
pressure cannot build up above the air pressure
on the ground. (Hint, skydivers altimeters
should never go below „0“.)
It is the skydiver‘s responsibility to make sure that
jump pilots are informed of these circumstances
that will interfere with the proper function of
CYPRES. Should a jump pilot be unable to comply
with these requirements, or should you discover
after a jump that the requirements have not been
met, you have to switch CYPRES off and on
again prior to the next jump. Note that the above
conditions will only lead to a low, or no activa-
tion - therefore there is no risk of a high activation.
Take care to not exceed the activation velocity near
or below the activation altitude(s) when descend-
ing with skydivers. Our measurements indicate
that extraordinary rates of descent are achieved
in turbine aircraft, as the pilot is concentrating on
