AUXILIARY FUEL TANK
The auxiliary fuel tank can be installed between the LH and the RH main fuel
tanks (Ref.: RFM Supplement 15) or longitudinally above the LH main fuel
tank extending aft inside the baggage compartment (Ref.: RFM Supplement
65). The auxiliary fuel tank is an anti-crash, bladder-type tank with a capacity
of 500 litres (400 kg).
At the bottom of the auxiliary fuel tank are installed two auxiliary ducts that
connect the auxiliary fuel tank with the no.1 and no.2 main fuel tanks. All
tanks (main and auxiliary) are refuelled through the same filler neck.
The vent line of the auxiliary fuel tank is connected to the vent line of the two
main tanks (left and right).
One electrical connector connects the auxiliary tank to the Fuel Computer
Unit (FCU) which automatically adjusts for the fuel contained in the auxiliary
tank.
No probes are installed inside of the auxiliary tank.
