Real-time Wavelet Flight Data Evaluator for System Identification of Flight Characteristics

Performance of system identification of aircraft flight characteristics quite depends on flight data to be analyzed.In order to make the system identification more useful and reliable, a real-time flight data evaluator which determines appropriate parts of data is proposed.The proposed method is characterized by multi resolution analysis (MRA), a kind of wavelet transform, and validates flight in both time and frequency domains.Results to apply the proposed methods to both simulated and real flight data show that the proposed method has adequate capability to extract desirable parts from flight data.
