2.24 Ventilation
2 eyeball vents mounted
at either side of the
canopy frame provide
fresh outside air. The
vents are connected to
NACA scoops on the
canopy. Turning the rim
adjusts air volume.
2.25 Electrical System
The electrical system uses a single wire supply and chassis (negative) return for all equipment
except avionics units which have their own negative wire returns.
Power for all services except engine ignition is provided by a LiFePO4 (Lithium ion Iron Phosphate)
battery mounted on the firewall and charged via the engine’s alternator and rectifier-regulator. The
battery has its own integrated cell protection and balancing circuits.
All circuits except the starter motor are protected by individual circuit breakers mounted on the right
hand side of the instrument panel. The main battery supply carries a 30A circuit breaker. Circuit
diagrams for each of the systems are given in Appendix 5.
2.26 Pitot-Static System
The pitot static tube, located under the port wing near the aileron root, provides both dynamic and
static pressures to the instruments via flexible plastic hoses.
Moisture and dirt collection reservoirs are installed inside the cockpit, on the left sidewall in front of
the pilot’s seat.
2.27 Galaxy Ballistic Rescue System GRS 6 473 SD B2
The rocket engine and parachute is situated under the front scuttle and is designed to fire through
a break away panel. The parachute is attached at 3 points on the fuselage, the first two being the
port and starboard firewall cross-member, the third point can be found on the port side behind the
pilot’s seat. The red activation handle is easily visible on the lower edge of the instrument panel
next to the throttle.
IMPORTANT
Before working on the aircraft, ensure that the safety locking pin is inserted in the
parachute deployment handle on the panel. If working on or near the parachute itself,
ensure that the transit safety pin is inserted.
Refer to the parachute manufacturer’s maintenance manual for details of maintenance
required.
WARNING
Avoid blowing into the pitot-static system with the collection reservoir covers on - this
may cause damage to the instruments.
WARNING
The battery will be damaged if allowed to completely discharge or if it is jump
started. Only use the recommended charger. See battery manufacturer’s
maintenance manual.
