Abstract:
1. An on-board device for measuring the weight of an aircraft (G) having a plurality of undercarriages (T 1 , T 2 ), each undercarriage (T 1 , T 2 ) being provided with a hollow element extending from a first end to a second end and carrying at least one ground-contacting member, which element is deformable under the action of the weight of the aircraft standing on a surface, said device comprising said hollow element and a bar extending inside said hollow element from an embedded end to a free end, a top internal zone (ZSUP) of said hollow element being above said free end, and said free end being above a bottom internal zone (ZINF) of said hollow element opposite the top internal zone (ZSUP), wherein said free end has a first sensor and a second sensor respectively for taking a first measurement relating to a top distance (DSUP) between said free end of said top internal zone (ZSUP), and a second measurement relating to a bottom distance (DINF) between said free end and said bottom internal zone (ZINF), said device including firstly processor means connected to the first and second sensors for generating an alert when a sum of the first measurement plus the second measurement varies, and secondly a processor unit connected to at least one of said sensors in order to determine information relating to weight.
