1. A process for detecting on an aircraft an overshoot of design loads at the level of a structural part of said aircraft, according to which process the following steps are carried out repetitively and automatically:

  • a) an effective speed of the aircraft is measured;

    b) a first comparison is carried out, by comparing this measured effective speed with at least one maximum speed relating at least to the current flight configuration of the aircraft;

    a vertical load factor of the aircraft is measured;

    a second comparison is carried out, by comparing said measured vertical load factor with at least one limit value of the vertical load factor; and

    c) one determines whether a structural inspection needs to be performed at the level of said structural part, at least on the basis of the result of said first and second comparisons, wherein, repetitively and automatically;

    before said step c);

    the value of at least one additional particular parameter is measured, said additional particular parameter being chosen from one of the following parameters;

    the weight of the aircraft;

    the centering of the aircraft;

    the dynamic pressure; and

    at least one particular cue; and

    an additional comparison is carried out, by comparing said measured value with at least one limit value of said particular parameter; and

    in said step c), one determines whether a structural inspection needs to be performed at the level of said structural part, by also taking account of the result of said additional comparison.
