First Claim
1. A computer-implemented method for modeling performance of an aircraft through adaptive aircraft performance models using aircraft performance data, the aircraft performance data at least comprising recorded trajectory data of the aircraft, weather data faced during trajectory of the aircraft, aircraft configuration data and an aircraft intent, the method comprising:
- using a nominal aircraft performance model of the aircraft, wherein the nominal aircraft performance model comprises a polynomial description of aircraft performance;
identifying aircraft degradation coefficients that instantiate engine degradation and airframe degradation in the polynomial description of aircraft performance;
replacing nominal values of the aircraft degradation coefficients with degraded values that approximate a degradation in aircraft performance to generate a degraded aircraft performance model of the aircraft;
calculating computed trajectory data based on;
the aircraft intent, which represents the recorded trajectory data;
the weather data; and
the degraded aircraft performance model;
comparing the recorded trajectory data with the computed trajectory data to obtain a result;
when the result of the comparison is less than a previously established threshold, obtaining an enhanced aircraft performance model by considering the degraded aircraft performance model as the enhanced aircraft performance model;
when the result of the comparison is higher than the previously established threshold, modifying the aircraft degradation coefficients and repeating the steps of generating the degraded aircraft performance model and calculating the computed trajectory until the result of the comparison is less than the previously established threshold; and
modeling the performance of the aircraft utilizing the enhanced aircraft performance model.
