Abstract
The invention relates to a method and to a device for detecting a degradation of flight performance of an aircraft that is in flight, wherein current flight status data of the aircraft that is in flight are first determined. A flight performance index is then calculated on the basis thereof. Furthermore, on the basis thereof, a nominal flight performance reference index is determined by means of a flight performance model, wherein a degradation of flight performance can be inferred by comparing the two indices.
Claims19
A method for detecting a degradation of flight performance of an aircraft in flight, comprising:
- a) determining a current flying state of the aircraft in flight, the current flying state from a plurality of values comprising of flying state parameters that influence or characterize the flight performance of the aircraft, which are at least partially recorded by means of sensors provided on the aircraft,
- b) calculating a current flight performance indicator from one or more flying state parameters of the currently determined flying state by means of an electronic evaluation unit,
- c) determining a nominal flying performance reference indicator from the a flight performance model of the aircraft in flight which replicates a nominal flight performance of the aircraft in the non-degraded flying state, wherein the flight performance model is provided in dependence on one or more flying state parameters of the currently determined flying state by means of the electronic evaluation unit, and
- d) detecting a degradation of the flight performance of the aircraft in flight in dependence on a comparison between the current flight performance indicator and the nominal flight performance reference indicator if the deviation is greater than a predetermined limit value by means of the electronic evaluation unit.
