Flight profile recognition is a hot issue in aircraft four-dimensional (4D) trajectory prediction. A novel method based on aircraft meteorological data relay (AMDAR) data is proposed to generate flight profile. The method includes a nominal altitude profile constituted with altitude-range and a nominal speed profile constituted with speed-time. Firstly, the dynamic space warping (DSW) algorithm is applied in calculating the similarity distance of flight altitude profile while generating the nominal flight altitude profile. Then the large oval distance algorithm combining with the base of aircraft data (BADA) model is proposed to achieve a nominal flight speed profile when ground speed is unknown. Flight intent and meteorological factors retained in AMDAR data are observed in the calculated flight profiles. A case study demonstrates that the proposed approach can effectively provide a complete flight profile reflecting the real aircraft flight status.
