OPERATING PROCEDURES - CONT
WARNING
When the AR2 is used on the reserve parachute, the main parachute must be
activated at an altitude high enough to obtain a fully deployed canopy at least
1,500 feet above the actuation altitude for the AR2. If the main parachute opens
within only a few hundred feet of the AR2 actuation altitude, the AR2 may deploy
the reserve parachute. The two parachutes may become entangled, which may
result in death of parachutist.
WARNING
The JUMP/OFF switch must be set to OFF immediately after every jump. Setting
the JUMP/OFF switch to OFF repositions the mechanism for the next jump and
prevents inadvertent actuation on the ground or during transport. If the switch is
left in JUMP position, the next jump will cause the AR2 to actuate prematurely.
Two parachutes may deploy and become entangled, which may result in death of
parachutist.
7. After completing the jump, move the JUMP/OFF switch to OFF. Verify that switch is in the
detent position.
8. With the JUMP/OFF switch in the OFF position, prepare the AR2 for the next jump by
repeating steps 1 through 4.
9. After every jump and /or repack of the main chute the rigger is to inspect cable extension
length with the slack checker as follows:
