Abstract:
A method for validating or invalidating the computed weight of an aircraft, where the computed weight of the aircraft is determined by compiling various weight assumptions added to a known empty weight of the aircraft. The method measures the aircraft center of gravity, determines the percentage of computed weight supported by the combined main landing gear struts and the nose landing gear strut, and using a database such as a look-up table to validate if the percentage of computed weight is determined within a reasonable range to the measured load on the combined main landing gear struts and the nose landing gear strut. Sensors are attached to the landing gear struts, so to measure and monitor aircraft and center of gravity without measuring the aircraft weight.

Claim (Index 1):
A method of preparing an aircraft for take-off, the aircraft comprising main landing gear struts and a nose landing gear strut, the aircraft having a center of gravity, comprising the steps of:\n a. Loading passengers and baggage on the aircraft; b. Compiling, a planned take-off weight of the aircraft from assumptions of the weight of the passengers and baggage; c. Measuring the aircraft load supported by the main landing gear struts and the nose landing gear strut; d. Determining the aircraft center of gravity as a percentage of aircraft load supported by the combined main landing gear struts, from the measured aircraft load supported by the main landing gear struts and the nose landing gear strut; e. Applying the aircraft center of gravity percentage of load supported by the combined main landing gear struts to the planned aircraft take-off weight, to further determine the amount of the planned take-off weight supported by the nose landing gear strut; f. Determining from calibration data and the measured aircraft loads applied to the main landing gear strut an associated aircraft weight supported by the main land gear struts; g. Determining from calibration data and the measured aircraft loads applied to the nose landing gear strut an associated aircraft weight supported by the nose land gear strut; h. Comparing the determined associated aircraft weight supported by the main landing gear strut to the amount of the planned take-off weight supported by the main landing gear strut and comparing the determined associated aircraft weight supported by the nose landing gear strut to the amount of the planned take-off weight supported by the nose landing gear strut and determining if the planned aircraft weight is within a predetermined range; i. If the planned aircraft weight is within the predetermined range, dispatching the aircraft for take-off, and if the planned aircraft weight is not within the predetermined range, holding the aircraft from taking off.
