A method includes obtaining pressure data and temperature data for gas in respective ones of shock struts of a plurality of landing gear. The method includes determining, for each shock strut for a first time corresponding to an end of a first change in gas pressure due to movement of a piston of the shock strut during loading or unloading of the aircraft, a friction value associated with the shock strut based on a gas pressure and a gas temperature at the first time. The method also includes computing, for a particular time before the loading or the unloading of the aircraft causes a second change in gas pressure of one or more of the shock struts, a weight of the aircraft based on the gas pressures of the shock struts at the first times and the friction values associated with the shock struts at the first times.
