The Smoke Jumper CYPRES 2 is an Automatic
Activation Device for parachutes, which is built
for the needs of Smoke Jumper activities.
It initiates the reserve deployment sequence; if the
Smoke Jumper should still have a vertical speed
of more than 35 meters per second (78 mph) at
approximately 1200 ft AGL assuming the arming
handle was pulled at 3000 ft AGL.
The Smoke Jumper CYPRES 2 does its job by
severing the reserve closing loop allowing the
spring loaded pilotchute in the reserve container
to push away the aps of the container and to
jump out into the slipstream and initiate the re-
serve opening.
