Device and method for determining the weight and/or a characteristic value of the position of the centre of gravity of an aircraft
First Claim
1. A method of determining the weight and/or a characteristic value of the position of the centre of gravity of an aircraft standing on the ground by means of a plurality of undercarriages (1), 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.

Abstract
Method and device for determining the weight and/or a characteristic value of the position of the center of gravity of an aircraft standing on the ground by means of a plurality of undercarriages, each undercarriage including at least one structural element exhibiting a variable level of stresses depending on the fraction of the weight of the aircraft transmitted to the ground through the undercarriage. The method includes the steps of a) measuring on each undercarriage at least one parameter representing the stress level of the element; and b) evaluating the characteristic value and/or the weight according to the parameters measured in step a). At least one parameter measured in step a) is a magnetic or electrical characteristic of the structural element of the undercarriage.

- 8. A device for determining the weight and/or a characteristic value of the position of the centre of gravity of an aircraft standing on the ground by means of a plurality of undercarriages (1), each undercarriage (1) comprising at least one structural element (6, 8, 2) exhibiting a level of stresses that varies as a function of the fraction (Pi) of the weight of the aircraft transmitted to the ground through said undercarriage (1), this device comprising on each undercarriage (1) at least one sensor (15) for measuring a parameter representing the stress level of said element and means for determining the characteristic value as a function of the measured parameters, wherein the sensor is able to measure, as a representative parameter, a magnetic or electrical characteristic of the structural element (6, 8, 2) of the undercarriage (1).
