Cirrus Design Section 7
SR20 Airplane Description
The airplane may be serviced to a reduced capacity to permit heavier
cabin loadings. This is accomplished by filling each tank to a tab
visible below the fuel filler, giving a reduced fuel load of 13 gallons
usable in each tank (26 gallons total usable in all flight conditions).
Drain valves at the system low points allow draining the system for
maintenance and for examination of fuel in the system for
contamination and grade. The fuel must be sampled prior to each
flight. A sampler cup is provided to drain a small amount of fuel from
the wing tank drains, the collector tank drains, and the gascolator
drain. If takeoff weight limitations for the next flight permit, the fuel
tanks should be filled after each flight to prevent condensation.
Fuel Selector Valve
A fuel selector valve, located at the rear of the center console,
provides the following functions:
LEFT...................................Allows fuel to flow from the left tank
RIGHT .............................Allows fuel to flow from the right tank
OFF ........................................Cuts off fuel flow from both tanks
The valve is arranged so that to feed off a particular tank the valve
should be pointed to the fuel indicator for that tank. To select RIGHT or
LEFT, rotate the selector to the desired position. To select Off, first
raise the fuel selector knob release and then rotate the knob to OFF.
Fuel Quantity Indicator
A dual reading 2¼” fuel quantity indicator is installed on the console
immediately forward of the fuel selector valve. The LEFT pointer
indicates left tank fuel quantity and sweeps a scale marked from 0 to
28 U.S. gallons in 2½-gallon increments. The RIGHT pointer sweeps
an identical scale for the right tank. Each scale is marked with a yellow
arc from 0 to 8.2 gallon. The indicators are calibrated to read ‘0’ when
no usable fuel remains. Each indicator also provides an output signal
to illuminate the FUEL caution light when the fuel quantity goes below
approximately 8-9 gallons in each tank. The indicator is internally
lighted. 28 VDC for fuel quantity system operation is supplied through
the 5-amp ENGINE INST circuit breaker on the Essential Bus.
