BPRS: use, handling and maintenance
System description
The BPRS provides you with a chance to rescue yourself from an unexpected situation.
The system is placed inside a durable cylinder mounted on the starboard side of the aft battery bay.
The parachute is Inside this cylinder and stored inside a deployment bag with a rocket underneath.
This brand new design deploys a canopy that is not gradually drawn from the container or exposed to
distortion by air currents, but it actually opened safely in 0,4 to 0,7 seconds over at 50-60 ft above the
aircraft. It incorporates a special deployment bag, which decreases the risk of aircraft debris damaging
the canopy.
The BPRS is activated manually, by pulling the activation handle mounted on the top of the cabin
bulkhead. After being fired, the main canopy opens and fully inflates in about 3.2 seconds.
WARNING! Activation handle safety pin should be inserted when the aircraft is parked or
stored in a hangar to prevent accidental deployment. However, the instant pilot boards the air-
craft, the safety pin MUST be removed!
Using the BPRS
Typical situations for use of the BPRS are:
•
structural failure
•
mid-air collision
•
loss of aircraft control
•
motor failure over hostile terrain
•
pilot incapacitation (incl. heart attack, stroke, temp. blindness, disorientation...)
Prior to activating the system (if time permits):
•
shut the motor down and set the master switch to OFF
•
fasten safety harnesses tightly
•
protect your face and body
To deploy the parachute, firmly pull the activation handle out towards
the instrument panel until it extends at least 15” (38 cm) out of it’s
housing.
Once you have pulled the handle and the rocket has deployed, it will be about two seconds before
you feel the impact produced by two forces. The first force is that of the system stretching. The second
force follows after the canopy opens. It will seem as if the aircraft has pulled backwards briefly. The
airspeed is reduced instantly and the aircraft begins descending.
