Method and system displaying crosswind correction for approach to a runway
First Claim
1. A method of illustrating how to maneuver an aircraft to correct for crosswind, comprising:
- determining a difference between a current ground track and a current heading;
identifying a desired ground track;
calculating, in response to the determining and identifying steps, a desired heading required to maintain the desired ground track;
applying a gain factor to the desired heading resulting in a modified heading proportional to the difference between current track and desired heading; and
rendering on a display the current ground track, current heading, and an aircraft icon that is representative of the modified heading, the aircraft icon having a format different from the current ground track.

Abstract
An aircraft display system (100) for illustrating a suggested crab angle has a processor (104) adapted to receive data representative of a desired ground tract (214) and representative of a ground tract deviation, and is configured upon receipt of these data to supply a ground tract rendering display command. A display device (116) coupled to receive the ground tract image rendering display commands is operable to render an icon (222) representative of the desired aircraft heading to maintain the desired ground tract (214). The method of how to maneuver an aircraft to correct for crosswind includes determining (306) a difference between a current ground track (224) and a current heading (218), determining a desired heading to maintain the desired ground track (214) based on the difference, and rendering on a display an aircraft icon (222) that is representative of the desired heading.

12. A method of displaying an icon representative of a desired aircraft crab angle to compensate for a crosswind, comprising:
-
determining a current ground track; determining a current heading; determining a difference between the current ground track and the current heading; determining a desired ground track; determining, in response to the desired ground track and difference between the current ground track and the current heading, a desired heading reflective of the desired aircraft crab angle required to maintain the desired ground track; applying a gain factor to the desired heading resulting in a modified heading when the difference between the desired heading and the desired ground track is less than a threshold; and rendering on a display an aircraft icon that is representative of the modified heading, the aircraft icon having a format different than a displayed desired ground track. - View Dependent Claims (13, 14, 15, 16)

17. An aircraft display system comprising:
-
a processor adapted to receive data representative of a desired ground track, a current heading and data representative of a current ground track deviation, and configured upon receipt of these data to determine a desired heading required to maintain the desired ground track, and to apply a gain factor to the desired heading resulting in a modified heading when the difference between the desired heading and the desired ground track is less than a threshold, and supply a ground track rendering display command and a modified heading display command; and a display device coupled to receive the ground track image rendering display command and the modified heading display command and operable to render an icon representative of the modified heading to maintain the desired ground track.
