Abstract
An aircraft fuel-gauging system has multiple ultrasonic gauging probes providing fuel height outputs at several locations within a tank. The output of an inertial sensor is used to compute the attitude of the fuel surface with respect to the tank. The system uses the attitude information to determine whether outputs from a group of two or more probes are compatible with one another. Where a probe is identified as having an output incompatible with the fuel surface attitude and the outputs of other probes its output is excluded from the computation of the fuel quantity.
