1. A method of selecting weather data for use in at least one of a flight management system (FMS) of an aircraft and a ground station comprising:
- generating a reference aircraft trajectory using a reference data set comprising data points from a weather database along the trajectory, where the data points comprise a spatial position with associated weather data;
generating an approximate aircraft trajectory using a reduced data set comprising fewer data points than the reference data set;
comparing the reference aircraft trajectory to the approximate aircraft trajectory;
determining at least one difference between the reference aircraft trajectory and the approximate aircraft trajectory based on the comparison;
selecting a data point from the weather database corresponding to the determined at least one difference where the selected data point is not in the reduced data set, adding the selected data point to the reduced data set; and
providing to the at least one of the FMS and the ground station the associated weather data of the selected data point.

Abstract
A method of selecting weather data for use in at least one of a flight management system (FMS) of an aircraft and a ground station includes selecting a reduced set of weather data points to send to the FMS and taking into account a trajectory of the aircraft when determining what data points to include in the reduced set.

8. A method of selecting weather data for use in at least one of a flight management system (FMS) of an aircraft and a ground station comprising:
-
a) generating a reference aircraft trajectory using a reference data set comprising data points from a weather database along the trajectory, where the data points comprise a spatial position with associated weather data; b) generating an approximate aircraft trajectory using a reduced data set comprising fewer data points than the reference data set; c) comparing the reference aircraft trajectory to the approximate aircraft trajectory; d) determining at least one difference between the reference aircraft trajectory and the approximate aircraft trajectory based on the comparison; e) selecting a data point from the weather database corresponding to the determined at least one difference where the selected data point is not in the reduced data set; f) replacing a data point in the reduced data set with the selected data point; g) repeating steps b-f until the determined at least one difference satisfies a predetermined error threshold; and h) providing to the flight management system the weather data from at least some of the data points in the reduced data set. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
