U.S.
FUEL SYSTEM
(Continued)
FUEL SELECTOR VALVE
The fuel selector is a three-position selector valve, labeled BOTH,
RIGHT and LEFT. The fuel selector valve should be in the BOTH
position for takeoff, climb, landing, and maneuvers that involve
prolonged slips or skids of more than 30 seconds. Operation on either
LEFT or RIGHT fuel tank is reserved for level cruising flight only.
NOTE
•
When the fuel selector valve is placed in the BOTH
position, while in cruise flight, unequal fuel flow from
each tank may occur if the wings are not maintained
exactly level. Unequal fuel flow can be detected by one
fuel tank indicating more fuel than the other on the L
FUEL and R FUEL indicators. The resulting fuel
imbalance can be corrected by turning the fuel selector
valve to the fuel tank indicating the highest fuel quantity.
Once the L FUEL and R FUEL indicators have
equalized, position the fuel selector valve to the BOTH
position.
•
It is not practical to measure the time required to
consume all of the fuel in one tank, and, after switching
to the opposite tank, expect an equal duration from the
remaining fuel. The airspace in both fuel tanks is
interconnected by a vent line and, therefore, some
sloshing of fuel between tanks can be expected when
the tanks are nearly full and the wings are not level.
•
When the fuel tanks are 1/4 tank or less, prolonged
uncoordinated flight, such as slips or skids, can uncover
the fuel tank outlets causing fuel starvation and engine
stoppage. Therefore, if operating with one fuel tank dry
or operating on either LEFT or RIGHT tank with 1/4 tank
or less, do not allow the airplane to remain in
uncoordinated flight for periods in excess of 30 seconds.
