Gyrocopter and its Equipment
7.12 Fuel System
A diagram of the fuel system is included in the Aircraft Maintenance Manual.
Two connected composite fuel tanks are located close to the centre of gravity
of the empty gyrocopter, so the quantity of fuel in the tanks does not significantly
affect the behaviour of the machine in flight.
The capacity of the tanks is 120 lt.
Unusable fuel 2 lt.
The tanks are located
behind the seats. The
fuel level is easily seen from the scale attached to the
translucent fuel tank
walls. An additional fuel level gauge is located on the
instrument board.
It is essential to use
lead-free
car petrol with an octane minimum of 95
[RON 95] AKI 91
, An
octane level of 98
[RON 98]
is recommended if
available.
For fuels according to ASTM D4814 specifications following
AKI (Anti Knock Index) value has to be observed: min. AKI 91
NOTE:
AVGAS should not be used on a regular basis.
Average f
uel consumption at a cross-country speed of V
C
130 km/h (70kt) is
about 25
lt/h.
(6.6 US Gal/h)
7.13 Electrical System
The diagram of the electrical system of the gyrocopter is shown in Chapter 2 of
the Aircraft Maintenance Manual.
The main source of the aircraft’s electrical energy is a direct current generator
mounted on the engine. The master switch is located on the central panel and
is activated with the removable red key.
The electrical system provides power to all the electrical appliances in the
gyrocopter including the ignition system, magnetos,
cockpit, navigation
lights, pumps, sensors and any
additional appliances. On the side of the
instrument console, there is a 12V
socket (a typical car socket for a lighter)
giving the possibility of connecting
additional devices.
