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 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.

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.

18. A method of determining at least one of a weight and characteristic value of a position of a centre of gravity of an aircraft, comprising:
-
measuring on each undercarriage of the aircraft a stress level of at least one structural element of each undercarriage with a sensor attached to the at least one structural element, the sensor measuring at learnt one of a magnetic and electrical characteristic of the at least structural element; and evaluating the at least one of the weight and characteristic value according to the measuring, wherein, the at least one structural element exhibits a variable level of stress depending on the fraction of the weight borne by each undercarriage of the aircraft.
