Abstract

A method for displaying a flight path navigational procedure includes, but is not limited to, detecting with a position detecting system a current location of the aircraft, obtaining from an electronic storage device a plurality of flight path navigation procedures available for a geographic location, determining with a flight path analysis system a preferred flight path that will be taken by the aircraft, and displaying on a display unit a moving map corresponding with the current location of the aircraft and further displaying a depiction of the plurality of flight path navigation procedures on the moving map. The preferred flight path is displayed with a visual cue that visually differentiates the preferred flight path from the other flight paths of the plurality of flight path navigation procedures.
