Method for Modeling Aircraft Performance Through Adaptive Aircraft Performance Models
First Claim
1. A 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:
- introducing aircraft degradation coefficients in a nominal aircraft performance model of the aircraft to obtain a degraded aircraft performance model;
calculating computed trajectory data based on the aircraft intent that represents the 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; and
when the result of the comparison is higher than the previously established threshold, modifying the aircraft degradation coefficients and repeating the foregoing steps until the result of the comparison is less than the previously established threshold.

Abstract
A method for modeling aircraft performance including (a) introducing aircraft degradation coefficients in a nominal aircraft performance model of an aircraft and obtaining a degraded aircraft performance model, (b) calculating computed trajectory data in a trajectory computation infrastructure using as inputs aircraft intent which represents trajectory data, weather data, and the degraded aircraft performance model; (c) comparing the trajectory data with the computed trajectory data; (d) 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 less than a previously established threshold; and (e) modifying, when the result of the comparison is higher than the previously established threshold, the aircraft degradation coefficients and executing steps (a) to (e) of the method, until the result of the comparison is less than the previously established threshold.
