Abstract: An arrangement of sensors on the landing gear of an aircraft measure the weight and position of center of gravity of the aircraft. In order to compensate for errors caused by moment of torsion, one sensor each is arranged on a pair of lugs (53, 54) at two measurement points of an axle (55) or bogie beam lying opposite each other on the outside or of a shock-absorber landing-gear leg. Each of the sensors gives off an electric output variable corresponding to a vertical displacement (sensor deflection) between the lugs of a pair. The lugs (53, 54) are tapered at their roots (61, 62).
