FUEL SYSTEM (Continued)
FUEL QUANTITY INDICATORS
Fuel quantity is measured by eight fuel quantity transmitters (four in
each tank) and indicated by two electrically-operated fuel quantity
indicators on the upper portion of the instrument panel. The fuel
quantity indicators, which measure volume, are calibrated in pounds
(based on the weight of Jet A fuel on a standard day) and gallons. An
empty tank is indicated by a red line and the letter E. When an indicator
shows an empty tank, approximately 2.5 gallons (2.8 gallons in SIN
20880001 THRU 20880089 modified with
SK208-52 and SIN
20880090 and
On) remain in the tank as unusable fuel. The left and
right fuel quant~ty hd~cators each recelve power from a "pull-off' type
clrcult 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.
WARNING
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.
WING TANK FUEL LOW WARNING ANNUNCIATORS
Two amber fuel low warning annunciators, one for each wing tank, are
located on the annunciator panel. The annunciators are labeled LEFT
FUEL LOW and RIGHT FUEL LOW. Each annunciator will illuminate
when the fuel in the respective tank is 25 gallons or less.
