4.2.3.3

Refueling of (optional) wing tank(s)

One or two flexible wing fuel tanks are optionally available.

The wing fuel tanks are connected to the fuselage fuel system with one fuel line
and one vent line each. Both lines are equipped with quick-disconnect couplings,
which must be connected manually when rigging the wings.

The wing fuel tanks are filled via the fuselage fuel tank by means of the built-in
refuelling pump in the fuselage: As soon as the fuselage tank is completely filled,
the fuel that is pumped further is automatically fed into the wing fuel tanks.

For accurate control of the actual amount of fuel on board, it is recommended to
completely empty the wing fuel tanks before refueling, see page 4.2.3.8.

Before refueling the wing fuel tanks, ensure that the vent lines of the wing fuel
tanks are also connected to the fuselage. Otherwise overflowing fuel from the wing
fuel tanks may also enter the fuselage during flight!

In order to achieve optimum filling of the wing fuel tanks, the wings should be kept
horizontal when refueling.

The wing fuel tanks do not have their own level measurement. Therefore it is
recommended to use calibrated container for refueling the aircraft, especially when
using wing fuel tanks. This makes it easy to determine the total amount of fuel
being refueled.
