| 摘要 |
The invention relates to a method for enhancing nominal aircraft performance models (APM) using flight data from operational aircraft. More specifically, the invention parameterizes the degradation of the aircraft performance caused by engine ageing (thrust reduction), reduced efficiency of aerodynamic surfaces, etc. The present invention obtains an enhanced APM by comparing the recorded trajectory data, collected in flight, with a computed trajectory data that consider the degradation of the aircraft performance over time, in an iterative manner until a predefined threshold is reached. This improves accuracy of the aircraft performance models available for trajectory prediction by accounting for degradation in performance. |
