Patent Images
1. A method for indicating on a display device associated with an aircraft whether the aircraft is satisfying defined criteria for a maneuver, the method comprising:
- displaying a graphical representation on the display device of a procedure turn symbol associated with a procedure turn from a navigation point, the procedure turn corresponding having a maximum distance criterion from the navigation point, and a minimum altitude criterion; and
providing an alert by displaying a first visually distinguishing characteristic if a current altitude of the aircraft is below the minimum altitude criterion, and a second visually distinguishing characteristic if a current distance from the navigation point is beyond the maximum distance criterion.

Abstract
Methods and systems are provided for displaying visually distinguishing characteristics if an aircraft is below a minimum altitude or beyond a maximum distance when executing a procedure turn. A procedure turn icon, an aircraft icon indicating the aircraft'"'"'s present location, terrain/obstacles, and the visually distinguishing characteristics are displayed on a moving map.

9. A method for indicating on a display device associated with an aircraft whether the aircraft is satisfying defined criteria for a maneuver, the method comprising:
-
identifying a procedure turn; displaying symbols on the display device for the current location of the aircraft and the procedure turn; providing a first alert if the current altitude of the aircraft will be going below the minimum altitude based on current flight parameters, or is below the minimum altitude; providing a second alert if the current distance from the navigation point will be going beyond the maximum distance based on current flight parameters, or is beyond the maximum distance; and repeating from the displaying symbols step. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for notifying the aircrew of an aircraft when exceeding a minimum altitude and a maximum distance during execution of a procedure turn, comprising:
-
a flight management system configured to; store data including the minimum altitude and the maximum distance for the procedure turn; determine the current location and altitude of the aircraft; and determine if the aircraft is below the minimum altitude value or beyond the maximum distance; a display device configured to; display a moving map including terrain; display an icon of the aircraft in its current location on the moving map; display an icon of the procedure turn on the moving map; display a first visually distinguishing characteristic if the aircraft goes below the minimum altitude value; and display a second visually distinguishing characteristic if the aircraft goes beyond the maximum altitude value. - View Dependent Claims (17, 18, 19, 20)
