The pin is inserted through the handle retainer and barrel locking the
handle in the "safe" position. A "Remove Before Flight" streamer is
attached to the pin.
After maintenance has been performed or any other time the system
has been safetied, operators must verify that the pin has been removed

Deployment Characteristics

When the rocket launches, the parachute assembly is extracted outward
due to rocket thrust and rearward due to relative wind. In approximately
two seconds, the parachute will begin to inflate.
When air begins to fill the canopy, forward motion of the airplane will
dramatically be slowed. This deceleration increases with airspeed but in all
cases within the parachute envelope should be less than 3 g's. During this
deceleration a slight nose-up may be experienced, particularly at high
speed; however, the rear riser is intentionally snubbed short to preclude
excessive nose-up pitch. Following any nose-up pitching, the nose will
gradually drop until the airplane is hanging nose-low beneath the canopy.
Eight seconds after deployment, the rear riser snub line will be cut and the
airplane tail will drop down into its final approximately level attitude. Once
stabilized in this attitude, the airplane may yaw slowly back and forth or
oscillate slightly as it hangs from the parachute. Descent rate is expected to
be less than 1700 feet per minute with a lateral speed equal to the velocity
of the surface wind. In addition, surface winds may continue to drag the
airplane after ground impact.
Ground impact is expected to be equivalent to touchdown from a
height of approximately 13 feet. While the airframe, seats and
landing gear are designed to accommodate this stress, occupants
must prepare for it in accordance with Section 3 -
The CAPS is designed to work in a variety of airplane attitudes,
including spins. However, deployment in an attitude other than
level flight may yield deployment characteristics other than those
