If your aircraft has tank fill tabs and no auxiliary tanks, you can
use the auxiliary tank feature to select either filling to the tank tabs
or topping the tank. See “Main Tank Capacity” and “Auxiliary
Tanks” beginning on page 15 to program the FS-450M for this
feature. The FS-450M does not differentiate fuel flow between the
main and auxiliary tanks; it considers only total fuel in the aircraft.
If you added less than full fuel, then tap AUTO to select
. Then tap STEP. The next display will ask
you how much you added:
(or selected
units). Hold the AUTO button to count up, tap the AUTO button to
count down. The count up will stop at full tanks, since you cannot
add more fuel than would top the tanks. Tap STEP to complete the
entry and advance to the Manual indexing mode.
If you removed fuel from the aircraft or wish to correct the total
quantity of fuel on board, you can “add” a negative amount of fuel.
