Claim 0:
1. A method of determining aircraft weight, the aircraft having landing gear struts, each landing gear strut comprising a piston telescoping in a cylinder, the strut comprising fluid and a seal, the piston experiencing breakout friction with the cylinder, comprising the steps of:
a. taxiing the aircraft so as to cause taxi induced telescopic movement of the piston within the cylinder over time;
b. measuring a pressure over time of the fluid during such taxi induced telescopic movement, the measured pressure having high pressure values and low pressure values;
c. identifying an asymmetry of the high and low pressure values about a mean of the measured pressures;
d. applying a correction factor to the measured pressures to determine weight of the aircraft, with the correction factor including the identified asymmetry.
