Determining a descent trajectory described by an aircraft intent description language (AIDL)
First Claim
1. A method comprising:
- accessing historical flight data for a recorded flight trajectory, the recorded flight trajectory having been performed by a first aircraft of a first aircraft type of multiple aircraft types and for a first airline of multiple airlines;
calculating, using a trajectory predictor, a plurality of trajectories for the first aircraft using (1) an initial condition of the first aircraft, and (2) a plurality of values for an aircraft intent parameter;
determining, using an optimization module, an optimal value of the plurality of values for the aircraft intent parameter that results in a calculated trajectory that best fits the recorded flight trajectory;
mapping the optimal value of the aircraft intent parameter to a combination of the first aircraft type, the first airline, and an identified intended descent procedure;
providing, in response to a request to predict a trajectory of a second aircraft of the first aircraft type, the first airline, and the identified intended descent procedure, the optimal value of the aircraft intent parameter from the optimization module to the trajectory predictor; and
calculating, using the trajectory predictor, a trajectory of the second aircraft using (1) an initial condition of the second aircraft and (2) the optimal value of the aircraft intent parameter.

Abstract
Determining a descent trajectory described by an Aircraft Intent Description Language (AIDL) is disclosed. An example method includes accessing historical flight data for a recorded flight trajectory, the recorded flight trajectory having been performed by a first aircraft type of multiple aircraft types and for a first airline of multiple airlines; estimating, using a processor, an aircraft intent parameter and an initial condition of the recorded flight trajectory based on an aircraft intent description language (AIDL) representation of the recorded flight trajectory; and mapping, using the processor, the aircraft intent parameter and the initial condition to a combination of the first aircraft type, the first airline, and an identified intended descent procedure.
