ABSTRACT:
An on-board aircraft system for determining the weight and load-related characteristics of an aircraft having landing gear struts (which each have a strut cylinder, a strut piston, and a working fluid in the strut cylinder) includes an accelerometer associated with each gear strut for measuring acceleration. The system further includes a pressure-adjustment means coupled to each strut cylinder for selectively adjusting the pressure in each strut cylinder to cause each landing gear strut to extend and retract; a plurality of pressure transducers coupled to the plurality of landing gear struts for measuring a pressure in each strut cylinder; and a computer. The computer is operable to cause retracting and extending the strut, to store pressure measurements of the strut cylinder during the retraction and extension of the strut, to store acceleration measurements corresponding to each pressure measurement taken, and to calculate the weight based on the pressure measurements and the acceleration measurements. A method of determining the weight on an aircraft is disclosed that includes use of an accelerometer.
