DESCRIPTION
7.7 - FUEL SYSTEM
(Figure 7.7.1)
The fuel system comprises fuel tanks, fuel unit, selectors (manual and automatic), electric and mechanical boost
pumps, engine fuel system, gaging installation, monitoring installation and drains.
FUEL TANKS
Fuel tanks are formed by sealed casings in each wing. Each fuel tank comprises a filling port located at the end of
wing upper surface, two drain valves located at the lower surface (one near main landing gear, at trailing edge side,
the second one near wing root side, at leading edge), a vent valve located on the lower surface, a suction strainer
and three level gages.
FUEL UNIT
The fuel unit combines shut-off valve, tank selector and filter functions. It is connected to the manual selector
through a mechanical control. The fuel filter is located in a bowl at the lower part of the unit. It is fitted with a by-pass
valve, a clogging indicator and a drain valve.
TANK MANUAL SELECTOR
(Figure 7.7.2)
The tank manual selector is located on the pedestal rear face. It allows selecting the tank (R or L) to be used and
setting unit to OFF. To change from L position to OFF position, turn the selector clockwise (L → R → OFF) ; change
from R position to OFF position requires a voluntary action from the pilot (pull and turn). The "pull and turn"
"FUEL OFF"
maneuver prevents involuntary operation. When the unit is set to OFF, the
CAS message
remains visible.
