1. 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.
