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 t...
[ What is claimed is:] [11.] A method for determining weight on an aircraft gear strut having a strut cylinder with a working fluid and a strut piston, the method comprising the steps of: retracting and extending the strut;taking and storing strut cylinder pressure measurements during the retraction (P.sub.r) and extension (P.sub.e) of the strut;taking and storing acceleration measurements (a.sub.r and a.sub.e) corresponding to each pressure measurement taken; andcalculating the weight on the strut based on the pressure measurements and the acceleration ...
