Fuel Quantity Indicators
53.
Fuel Gauges. Fuel quantity is measured by a float operated, variable resistance
transmitter in each tank and input to the EDM 930 Engine Data Management System. Useable
fuel in each tank is displayed on the EDM 930 in US gallons. The fuel gauges in this aircraft are
not reliable for precise measurement of fuel remaining. Pilots shall follow the guidelines
detailed in Part 2
– Fuel Management.
54.
Fuel Totalizer. The EDM 930 features a fuel quantity totalizer system. The pilot must
manually enter the total useable fuel at the start of each flight, and through monitored fuel flow
the EDM 930 calculates the useable fuel remaining. This system has been proven to be
accurate to within 5% if the starting fuel quantity is entered correctly.
Rotary Fuel Selector Valve
55.
Fuel is fed from the wing fuel tanks by gravity through a three position rotary selector
valve and strainer. Fuel is then collected in the header tank, from where it is fed through the
firewall to the engine. Fuel will flow to the header tank whenever the Fuel Selector Valve is in
the BOTH, LEFT or RIGHT positions.
Figure 1-35 Fuel Selector Valve
NOTE
The OFF position of the fuel selector valve is disabled in compliance
with STC SA00152WI.
NOTE
Except when required to correct a significant fuel imbalance in flight,
the aircraft should be operated with the fuel selector in BOTH at all
times.
