Abstract
An aircraft fuel-gauging system has flowmeters at the inlet and outlet of a fuel tank. The output of the flowmeters is used to compute the height and volume either of a localised elevated region above the inlet, where fuel flows into the tank, or of a localised depressed region above the outlet where fuel flows out of the tank. Where the gauging probes are located away from the region of the inlet or outlet, the volume derived from the probes is corrected by adding the volume of the elevated region or by subtracting the volume of the depressed region. Where the gauging probes are located in the region of the inlet or outlet, the height output of the probe is corrected either by subtracting the height of the elevated region or by adding the height of the depressed region. The volume is computed from these corrected heights and further corrected by adding the volume of the elevated region or by subtracting the volume of the depressed region.
