Example C: Aircraft has two MAIN tanks.
When you partially refuel, use:
‘ADJUST? +0.0’: use this to add the amount of fuel you pumped
into the aircraft (it doesn’t matter which tanks you added
to - the EDM totalizes ALL onboard usable fuel). In this
example you will add ‘+14.0 GAL’, the same as your fuel
slip reads. This will be added to the totalizers REM value.
