9.4.8.2 Accumulate Total—Trip Total
You may either display total fuel used since the last time
you informed the EDM that the aircraft was refueled, or
for an extended trip with multiple fuel stops. This
selection affects only the USD parameter.
9.4.8.3 Resetting "USED"
Every time you inform the EDM that the aircraft is
refueled, the amount of fuel used is set to zero, unless
the instrument is programmed to accumulate. The
display of fuel used pertains only to the fuel used since
the last time you informed the EDM that the aircraft was
refueled. To reset to zero the amount of fuel used at any
point in time, manually step to display USD and hold both
buttons for five seconds until the display shows .0 USD.
9.4.8.4 Fuel Management
CAUTION
For fuel calculations to be accurate, it is imperative that
you inform the EDM of the correct amount of fuel
aboard the aircraft. Do not rely on fuel flow instruments
to determine fuel levels in tanks. Refer to original fuel
instrumentation for primary information.
The EDM Fuel Flow uses a small, turbine transducer that
measures the fuel flowing into the engine. Higher fuel
flow causes the transducer turbine to rotate faster which
generates a faster pulse rate. Because the transducer
turbine generates thousands of pulses per gallon of fuel,
it can measure with high resolution the amount of fuel
that flows into the engine.
