Aircraft`s e.g. freight type wide-bodied airliner, weight and position of center of gravity determining method, involves measuring electrical or magnetic characteristics of unit to evaluate characteristic quantity and weight of aircraft
The method involves measuring the electrical or magnetic characteristics representing a constraint level of a structural unit e.g. vertical stay rod, keel beam and axle system, on each of the landing gears, using an on-line eddy current sensor. A characteristic quantity and the weight of an aircraft are evaluated based on the measured characteristics. The characteristics are selected from a group comprising magnetic permeability, electrical conductivity and electrical permittivity. The unit presents the constraint level based on a fraction of the aircraft weight carried by the landing gears. An independent claim is also included for a device for determining the weight and a characteristic quantity for a center of gravity of an aircraft resting on the ground.
