En-route Fuel Planning
58.
This aircraft is equipped with several tools to assist the pilot with the task of fuel
management. Of particular significance / use are the following:
a.
Fuel Quantity Gauges. Fuel quantity gauges show the useable fuel in each tank.
The fuel gauges are considered reliable only when the tanks are completely full,
completely empty, or when fuel levels are below 1/2;
b.
EDM 930 Fuel Totalizer. The EDM 930 displays total useable fuel remaining,
calculated using measured fuel flow rate. The accuracy of the totalizer depends
on the pilot entering the correct fuel quantity at the start of the flight. This shall be
based on either completely full fuel tanks, or a precise confirmation of useable
fuel on board by dipping both tanks;
c.
EDM 930 Fuel Management Data. The EDM 930 will display useable fuel
remaining, fuel flow rate, and time remaining to empty at current consumption
rate;
d.
EDM 930 Low Fuel Alerting. The EDM 930 will provide fuel alerts:
(1) Low Fuel Flow. Low fuel flow rate will trigger an alert, as low fuel flow in
flight may indicate imminent engine failure. With the throttle closed on the
ground, a low fuel flow alert may be triggered;
(2) Low Fuel Quantity
– Fuel Tanks. If the fuel quantity in either tank drops
below 9 USG, a low fuel alert for the specific tank will be displayed, and
(3) Low Fuel Quantity - Totalizer. If the useable fuel remaining consumed at
the current fuel flow rate will provide less than 45 minutes of flight time, a low
fuel alert will be displayed.
WARNING
Takeoff shall not be commenced with less than 15
USG total useable fuel as indicated by the totalizer, or
with the combined totals of the two fuel tank gauges
indicating less than 20 USG.
e.
Garmin GPS. When conducting cross country operations, the GPS will provide
Estimated Time Enroute (ETE) to the final destination. When compared to the
“time remaining to empty” feature of the EDM 930, the pilot can accurately
monitor the adequacy of planned fuel reserves throughout the flight.
