1.7.4. Fuel quantity indicating system
The main fuel quantity gauge is located on the right AUX console and
indicates many different things depending on the position of the FUEL
QTY SEL knob placed on the centre pedestal (right of the HSI).
1. Total usable fuel remaining onboard is given on the bottom of the gauge in pounds of fuel
(numerical value) (except in TEST).
2. The F/R needle points to the amount of fuel in pounds remaining in the forward/right fuel
system according to the FUEL QTY SEL knob position.
3. The A/L needle points to the amount of fuel in pounds remaining in the aft/left fuel system
according to the FUEL QTY SEL knob position.
Here is a table explaining the interaction between the two instruments:
Fuel QTY
SEL
Fuel Totalizer (lbs)
A/L needle (in hundredths of pounds)
F/R needle (in hundredths of pounds)

Total lbs fuel RIGHT internal wing (max

EXT WING

Total lbs fuel LEFT external wing (max =25

Total lbs fuel RIGHT external wing (max
=25 for 370Gal)
EXT CTR

Total lbs Fuel external tank (max 2.0)
It is very important to know that the NORM position is the only position ensuring automatic fuel
transfer, trapped fuel warning and Bingo fuel computation based on fuselage fuel.
As a consequence if that knob is any other position than NORM you may not get accurate BINGO or
TRP FUEL warnings.
Please note that 4.34 introduced the possibility of flameout due to fuel starvation, even if the needles
are reporting some fuel remaining. Fuel gauges are notoriously inaccurate in airplanes, especially with
low fuel amounts, and this has been modelled in BMS to some extent.
