Storage

The fuel system consists of two tanks permanently connected with a big crossport, a single filler port,
fuel and ventilation lines, fuel level indications, and drain. The filler port is located at the left hand side
of the gyroplane. In order to open the filler cap, lift, then turn the flap, and pull out. Reverse to close
cap.
The tanks are installed behind the seats and have a capacity of 100 litres. Fuel level can be checked
visually using a dip stick which has to be inserted diagonally from the fuel filler port.
Ventilation is provided by a vent line above the tanks leading through the mid channel directly to the
outside.

Distribution

The fuel distribution system comprises fuel hoses, made of fabric-reinforced rubber, a shut-off valve,
filters and pumps.
Possible fuel system versions differ with engine model, see schematics below. In case of ROTAX 914
engine variant, the fuel line with the second fuel pump P2 has a non-return valve to prevent flow-back
when the second pump is switched off.
