Pilot error is reduced and auto pilot operation is improved by the addition of capture information to the information provided on a cockpit display. The capture information, such as, for example, capture start point, last point to initiate capture, trajectory during capture, and capture overshoot region provide information to the pilot regarding the correct initiation of capture. Pilots are therefore better able to evaluate the ongoing performance of the automation or auto pilot systems and to trust that the auto pilot is functioning as desired. Furthermore, the pilot operating the aircraft in manual mode receives guidance based on this information to better know when to initiate capture of the assigned altitude or vertical path.

1. A method for providing information to a pilot of a vehicle via a display, the method comprising the steps of:a) indicating a current position of said vehicle on said display; b) receiving a target position for said vehicle; c) determining a first capture initiation position, said first capture initiation position differing from said current position and corresponding to a point for said vehicle to initiate capture in order to obtain said target position from said current position; d) receiving a maximum permissible overshoot; e) determining a last capture initiation position such that said target position to be captured will be overshot by no more than said maximum permissible overshoot, wherein the region between said first capture initiation position and said last capture initiation position forms a capture region; and f) displaying (i) said first capture initiation position on said display in conjunction with said current position of said vehicle and (ii) said capture region relative to said current vehicle position. 2. The method of claim 1 wherein said first capture attribute is determined and displayed relative to said current attribute.3.

A digital storage medium having instructions stored thereon configured to execute the method of claim 1.17. A method for providing feedback comprising the steps of:a) providing an automated control system; b) providing an altitude tape; a) providing a target altitude; d) displaying on said altitude tape a current aircraft altitude; e) displaying on said altitude tape a target indicator representing said target altitude; and f) displaying on maid altitude tape a path capture trajectory relative to said current aircraft altitude and corresponding to said target altitude indicator, said path capture trajectory including at least a first capture initiation altitude that differs from said current aircraft altitude, wherein said path capture trajectory is determined by said automated control system. 18. The method of claim 17 wherein said automated control system is an auto-pilot system.19. The method of claim 18 wherein said target altitude is a constant altitude.20. The method of claim 18 wherein said target altitude is defined by a path of ascending altitude.21. The method of claim 18 wherein said target altitude is defined by a path of descending altitude.22. The method of claim 18 wherein said target altitude is defined by a path computed as a function of vertical speed error.23. The method of claim 17 wherein the target indicator is a first icon, the current aircraft altitude is displayed by a second icon, and the path capture trajectory is displayed by a third icon.24. The method of claim 17 wherein the display screen is located in an aircraft.25. A display for an aircraft comprising:a sliding scale altitude indicator; a target altitude indicator on maid sliding scale altitude indicator configured to display a target altitude; a current altitude indicator on said sliding scale altitude indicator configured to display a current aircraft altitude; a capture region indicator on said on said sliding scale altitude indicator, said capture region indicator indicating at least an altitude, different from said current aircraft altitude, for initiating a capture of said target altitude; and an overshoot region indicator on said sliding scale altitude indicator. 26.
