Process and device for detecting on an aircraft an overshoot of design loads at the level of a structural part of said aircraft
First Claim
1. A process for detecting on an aircraft an overshoot of design loads at a level of a structural part of said aircraft, according to which process the following steps are carried out repetitively and automatically:
- a) measuring an effective speed of the aircraft;
b) performing a first comparison, by comparing said measured effective speed with at least one maximum speed relating at least to a current flight configuration of the aircraft;
measuring a vertical load factor of the aircraft;
performing a second comparison, by comparing said measured vertical load factor with at least one limit value of the vertical load factor; and
c) determining whether a structural inspection needs to be performed at the level of said structural part, at least on a basis of a result of said first and second comparisons,wherein, repetitively and automatically;
before said step c);
a value of at least one additional particular parameter is measured, said additional particular parameter being chosen from one of the following parameters;
a weight of the aircraft;
a centering of the aircraft;
a 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
step c) includes determining 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.

Abstract
A process and device for detecting on an aircraft an overshoot of design loads at the level of a structural part of the aircraft. The detection device includes a speed measuring device for measuring an effective speed of the aircraft. A first comparator compares the measured effective speed with a maximum speed relating to the current flight configuration of the aircraft. A vertical load measuring device measures a vertical load factor of the aircraft, and a second comparator compares the measured vertical load factor with a limit value of the vertical load factor. An inspection determining device determines whether a structural inspection needs to be performed at the level of the structural part, based of the results of the first and second comparisons.
