Abstract
The invention relates to a method of analyzing flight data recorded during N flights of at least one aircraft, by means of a flight data recorder of an aircraft, the data being grouped together by flight i in a signature vector of the flight Xof size d, the components of which correspond to data recorded during said flight i of the aircraft, a flight i being thus defined by the signature vector X, the method comprising the following steps: Gaussian kernel entropy component analysis of the flight signatures Xto obtain a zone of normal flights and classifying the flight signatures Xwith respect to their distance to said zone; determining, for each flight i, an abnormality score zdefined by the distance of a flight signature Xwith respect to the zone of normal flights; detecting, as a function of the abnormality score z, at least one abnormal flight.
