Abstract: A weight estimation system for estimating weight of an aerospace vehicle while grounded, the weight estimation system comprising a measurement subsystem including at least one sensor configured to measure a physical property in an interface that interfaces at least one of a fuselage and a wing with an undercarriage of said aerospace vehicle, in at least one area exhibiting a measurable change in geometry that is at least partly due to said weight, said measurement subsystem configured to produce measured data indicative of said weight of said aerospace vehicle; and a processor for receiving at least part of said measured data, said processor configured to estimate said weight, by relating said measured data with predetermined physical-property-to-weight correspondence data associated with said aerospace vehicle.
