Start Up Fuel
On power-up, you will be prompted to enter any fuel you might have
added to the aircraft (this process updates the REM and USD values).
The EDM will flash REFUEL? . If you didn’t add any fuel, simply tap
EXIT to quit, otherwise tap NEXT to pick one of the three quickset choices
below:
Choice 1) MAIN 66.0 GAL : Tap SAVE to accept or NEXT for choice
#2. This shortcut sets REM to the MAIN tank value (66 in
this case) you set up in your fuel computer.
Choice 2) MAIN + AUX 82.0 GAL : Tap SAVE to accept or NEXT for
choice #3. This shortcut sets REM to the sum of MAIN and
AUX you set up in your fuel computer.
Choice 3) Adjust? + 0.0 GAL : Tap either ADD or REMOVE to adjust
REM. Use when adding a partial amount of fuel. Tap SAVE
to accept adjustment or NEXT to repeat REFUEL?.
NOTE: If you forgot to perform your EDM REFUEL before starting
the engine, it can still be performed. The EDM will automatically
subtract any burned fuel from the value you choose (not applicable to
the ‘Adjust? + 0.0’ feature)
You are responsible for insuring that your usage of the REFUEL
feature results in the EDM’s REM parameter showing the correct
amount of usable fuel remaining onboard the aircraft.
The three examples, shown below, depict different aircraft tank
configurations and how you can update your EDM after refueling your
aircraft. These are meant to be general guidelines.
