Patent ID: 7484424

Claim:
A method of determining the weight and/or a characteristic value of the position of the centre of gravity of an aircraft having a plurality of undercarriages ( 1 ) standing on the ground, each undercarriage ( 1 ) comprising at least one structural element ( 6 , 8 ) exhibiting a variable level of stresses depending on the fraction (Pi) of the weight (P) of the aircraft transmitted to the ground through said undercarriage ( 1 ), this method comprising the following steps: a/ measurement on each undercarriage ( 1 ) of at least one parameter representing the stress level of said element; b/ evaluation of the characteristic value and/or of the weight according to the parameters measured in step a/; wherein at least one parameter measured in step a/ is a magnetic or electrical characteristic of the structural element ( 6 , 8 , 2 ) of the undercarriage.
