the FUEL QTY switch is in NORM. This was already a feature in SP3, but did not

include the information needed in the F-16's flight model data file.

¿ The mechanization for determining a fuel imbalance in SP3 is similar to real life, except

that the quantity needles should not overlap one another (a gray needle hides a red

needle). When the red needle started to appear an imbalance was occurring. New

code has been written to allow for more accurate looking needles--both for looks and

imbalance mechanization.

¿ With the new code/graphics an imbalance will look just like it does in real life, you will

see the red portion of the AL pointer showing when the needles are out of tolerance. In

Falcon, imbalances only occur if you feed from the FWD or AFT system, instead of

NORM, or in some special circumstances when the fuel system isn’t pressurized. So

getting back to the needles, in the C model, the needles are approximately 600 lbs

apart. In the D model, the AL system has more fuel than FR system (because of the

second cockpit) and the needles will be separated by 700-1350 lbs. If the needles

begin to separate by more or less than these amounts, an imbalance is occurring.

NOTE: The D model’s needles are different from the C model, and thus you will not get

the correct indications in a D model jet with the C model needles. Here is what the

needle model graphics should look like, more or less:
