Starter - Electric start
The starter is operated by start button on the instrument panel. The key switch must be in the ON position
for the starter button to function.
The key switch only switches the power to the instruments, comms & starter. Remember to switch on the
•
ignition switches before start-up!
The hand throttle cut out switch option makes it necessary for the hand throttle to be CLOSED in order for
•
the starter circuit to operate.

11.4. SECONDARY STRUCTURES AND SYSTEMS - BRAKING SYSTEM

The compensated rear wheel brakes are operated by a foot pedal on the left side of the front fork steering
bar. Brakes may be cable operated drum or hydraulic disc type according to aircraft specification. A brake
locking device is provided for parking. To lock, press the brake pedal and, with the left hand, lift the adjacent
locking lever and engage one of its slots with the hoop on the side of the steering assembly. Release occurs
automatically when the brake pedal is pressed.
Do not press on the end of the locking ratchet to engage parking brake. There is a risk it could bend.
•
• The travel of the hydraulic brake pedal will be such that the locking lever will engage only in the first or
second notches. This is normal.
•
Use Dot 4 brake fluid e.g. Bendix Universal Dot 4 from a sealed container.

SECONDARY STRUCTURES AND SYSTEMS - FUEL SYSTEM

Fuel is pumped from the single tank below the seat by the engine pump via the fuel filter. The 912S
installation features a recirculation system which returns excess fuel to the tank. The tank is vented via a
pipe to discharge clear of the aircraft. A sump with water drain is provided. The tank may be 49L or 65L, the
65L tank has a third mounting point at the centre of the tank. Fuel is supplied to the carburettors via the main
shutoff cock.
Rotax 912/912S
T
he preferred fuel is 95 RON minimum octane rating unleaded petrol. 4 star leaded fuel (super) can also be
used. 100LL AVGAS can be used, but the high lead content causes more plug fouling, so use only when
necessary. Plugs should be checked at least every 25 hours if using AVGAS. If AVGAS is used more than
just occasionally, use only semi-synthetic motorcycle oil.
Whichever type of fuel is used, use a reputable source of supply and during your daily inspection, use the
water drain facility provided in the fuel tank.
transparent container before the first flight of the day. Any water present will sink to the bottom. If any water
is found in the tank, check the carburettor fuel bowls for water before your next flight.
• Gasoline is extremely flammable and can be explosive under certain conditions.
• Refuel in a well-ventilated area with the engine stopped.
• Do not smoke or allow flames and sparks in the area where the engine is refuelled or where
fuel is stored.
• Turn the ignition and Master switches OFF. Earth the aircraft.
• Never fill the tank so that the level rises into the filler neck. If the tank is overfilled, heat may
cause the fuel to expand and overflow through the tank vents.
• After fuelling, make sure the fuel cap is securely replaced.
• Be careful not to spill fuel when refuelling. Spilled fuel or fuel vapour may ignite. If any fuel
is spilled, make sure the area is dry before starting the engine.
• Avoid prolonged or repeated contact with skin or breathing of vapour. KEEP FUEL OUT OF
REACH OF CHILDREN.
