SECTION 7 CESSNA
AIRPLANE AND SYSTEMS DESCRIPTION MODEL 208B 867 SHP
GARMIN G1000
U.S.
FUEL QUANTITY INDICATIONS
Fuel quantity is measured by four fuel quantity transmitters (two in each
tank) and indicated in the EIS section on the MFD below the oil
temperature indicators. The FUEL QTY indicators utilize twin vertical
scales that show fuel quantity for both the L and R tanks in LBS from 0
to 1000 in 200 pound increments. The fuel quantity indicators, which
measure volume, are calibrated in pounds (based on the weight of Jet
A fuel on a standard day). An empty tank is indicated by a red line.
When an indicator shows an empty tank, approximately 2.8 gallons
remain in the tank as unusable fuel. The left and right fuel level senders
each receive power from a pull-off type circuit breaker. The breakers
are labeled LEFT FUEL QTY and RIGHT FUEL QTY, respectively, and
are located on the left sidewall switch and circuit breaker panel.
Because of the relatively long fuel tanks, fuel
quantity indicator accuracy is affected by
uncoordinated flight or a sloping ramp if reading
the indicators while on the ground. Therefore, to
obtain accurate fuel quantity readings, verify that
the airplane is parked in a laterally level condition,
or if in flight, make sure the airplane is in a
coordinated and stabilized condition for at least 1
minute.
WING TANK FUEL LOW CAUTION ANNUNCIATORS
Two float sensors one for each wing tank will trigger the appropriate
amber L FUEL LOW or R FUEL LOW annunciation when the fuel in the
respective tank is 25 gallons (170 lbs) or less. When the fuel quantity in
each tank is less than 25 gallons (170 lbs), amber L-R FUEL LOW
annunciator will replace the previously displayed L or R FUEL LOW
annunciator.
