A weight and balance system which automatically compensates for loading errors while the aircraft is stationary. A weight signal is generated from the outputs of a pair of inclinometers mounted on adjacent opposite ends of a landing gear member which bends in response to aircraft weight. The weight signal generated just after no movement of the aircraft is detected is held in a latch. The held weight signal and a subsequently generated weight signal are combined to provide a signal representative of the difference therebetween. The difference signal is scaled by an error correction coefficient to provide a loading error compensation signal which is combined with the subsequently generated weight signal to provide a corrected weight signal. The system further includes means for performing reasonableness tests in response to the restoration of power to the system after power has been down. The reasonableness tests include determining whether the aircraft had been moved or whether there had been a load change during the power down. If movement of the aircraft is determined to have occurred, the latch is reset to hold the weight signal generated just after power to the system is restored. If a load change is determined to have occurred, a power down load correction signal is generated and combined with the loading error compensation signal and the subsequently generated weight signal to provide the corrected weight signal.

In a weight measuring system for an aircraft having a landing gear and means for generating a weight signal representing aircraft weight on the landing gear, a system for correcting loading errors in the generated weight signal comprising: means for holding a weight signal upon the occurrence of an aircraft condition; means for generating an error compensation signal from said held weight signal and a weight signal generated subsequent thereto; and means for combining the subsequently generated weight signal and the error compensation signal to generate a corrected weight signal.
