Abstract
An aircraft ultrasonic fuel-gauging system has a number of gauging probes in a tank arranged so as to include at least one set of three colinear probes. The outputs of the probes are supplied to a unit, which checks the operation of the probes in colinear sets by extrapolating height at one of the probes from the outputs of the other probes. Where there are two sets of colinear probes having a common probe it is possible uniquely to identify if the common probe is faulty. The system rejects any faulty probe and uses only the outputs of other probes in computations of fuel quantity.
