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.

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 defined by a first radial extending from the navigation point and having a length equal to a maximum distance criterion;displaying an aircraft symbol representing the aircraft in its current location;overlaying, on the display device, a shape representing a geographic area defined by the first radial, a second radial perpendicular to the first radial and extending a length equal to the maximum distance criterion from the navigation point, and an arc tracing out the maximum distance criterion between the first and second radial;displaying the procedure turn symbol in a first visually distinguishing characteristic if a current altitude of the aircraft is below a minimum altitude criterion; anddisplaying the shape in a second visually distinguishable characteristic when the aircraft symbol has departed the geographic area. 2. The method of claim 1, further comprising displaying the shape in a third visually distinguishing characteristic if the aircraft will be going below the minimum altitude criterion. 3. The method of claim 1, wherein the shape comprises an outline rendered in a first format, the method further comprising rendering the outline of the shape in a second format when the aircraft symbol has departed the geographic area. 4. The method of claim 1, further comprising displaying a moving terrain map associated with an instantaneous location of the aircraft on the display device, wherein the procedure turn symbol is displayed overlying the moving terrain map. 5. The method of claim 1, wherein the navigational point is proximate a landing location and associated with an approach path for the landing location, wherein the method further comprises displaying a graphical representation of the approach path on the display device. 6. The method of claim 1, further comprising providing an audible warning if the aircraft is departing the geographic area. 7. 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, the procedure turn defined by a first radial extending from the navigation point to a published maximum distance criterion from the navigation point, wherein the published maximum distance criterion is a distance for which the aircraft is not to exceed when flying the procedure turn;displaying symbols on the display device for the current location of the aircraft and the procedure turn;overlaying, on the display device, a shape having a first visually distinguishable characteristic and representing a geographic area defined by the first radial, a second radial perpendicular to the first radial and extending a length equal to the maximum distance criterion from the navigation point, and an arc tracing out the maximum distance criterion between the first and second radial, when the aircraft symbol is within the geographic area; anddisplaying the shape in a second visually distinguishing characteristic if a current altitude of the aircraft is below a minimum altitude criterion. 8. The method of claim 7 wherein the shape comprises a outline rendered in a first format, the method further comprising rendering the outline of the shape in a second format when the aircraft symbol has departed the geographic area. 9. The method of claim 7, further comprising displaying a moving terrain map associated with an instantaneous location of the aircraft on the display device, and wherein the symbols and shape displayed overlie the terrain map. 10. The method of claim 7, wherein the navigational reference point is proximate a landing location and associated with an approach path for the landing location, wherein the method further comprises displaying a graphical representation of the approach path on the display device. 11. The method of claim 7, further comprising providing an audible warning if the current altitude of the aircraft is less than the published minimum altitude criterion, or the current distance of the aircraft is beyond the published maximum distance criterion. 12. A system for notifying the aircrew of an aircraft when descending below or predicted to descend below a published minimum altitude criterion or beyond a published maximum distance criterion from a navigation point during execution of a procedure turn, comprising: a flight management system configured to: store data including the published minimum altitude criterion and the published maximum distance criterion for the procedure turn;determine the current or predicted location and altitude of the aircraft; anddetermine if the aircraft is below the published minimum altitude criterion or beyond the published maximum distance criterion;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 on the moving map a shape representing a geographic area associated with the procedure turn, the shape having a first visually distinguishing characteristic if the aircraft goes below the published minimum altitude criterion, the geographic area defined by first and second radials, each having a length equal to the maximum distance criterion, the first and second radials oriented perpendicular to one another, and an arc tracing out the maximum distance criterion between the first and second radial; anddisplay the shape in a second visually distinguishing characteristic if the aircraft goes beyond the published maximum distance criterion. 13. The system of claim 12 wherein: the flight management system is further configured to: determine if the aircraft will be going below the published minimum altitude criterion or beyond the published maximum distance criterion in consideration of current flight data; andthe display device is further configured to: display an outline of the shape in a third visually distinguishing characteristic if the aircraft will be going below the published minimum altitude criterion, and display the outline of the shape in a fourth visually distinguishing characteristic if the aircraft will be going beyond the published maximum distance criterion. 14. The system of claim 12, wherein the display device is further configured to: provide an audible alert if the current altitude of the aircraft is less than the published minimum altitude criterion, or the current distance of the aircraft is beyond the published maximum distance criterion.
