A method of measuring the weight of an aircraft is disclosed. The method comprises, in a self-propelled aircraft undercarriage having a electrical rotating machine, the steps of: measuring the current and voltage going into the rotating machine using current and voltage measuring means, calculating the power into the rotating machine, measuring the speed (or torque or acceleration) of said machine using speed sensing means, and comparing the power and speed (or torque or acceleration) results with a database of power and speed relationships of comparable...
1. A method comprising estimating weight of an aircraft, wherein said aircraft has an undercarriage fitted with an electrical rotating machine comprising a motor that propels the aircraft on the ground, said method further comprising: (a) supplying power to the electrical rotating machine and measuring power supplied directly using sensor means or indirectly using current and voltage supplied to the electrical rotating machine to obtain a power measurement;(b) when said aircraft is propelled on the ground, measuring a change in one or more of speed, acce...
