Anomaly detection of aircraft engine in FDR (flight data recorder) data [PDF]

open access: yesIET 3rd International Conference on Intelligent Signal Processing (ISP 2017), 2017
This paper deals with detection of anomalous behaviour of aircraft engines in FDR (flight data recorder) data to improve airline maintenance operations. To this end, each FDR data that records different flight patterns is first sampled at a fixed time interval starting at the take-off phase, in order to map each FDR data into comparable data space ...
