Methods and systems for displaying enroute moving maps

Methods and systems for a position indicating display system for an aircraft are provided. The system includes a moving map display representative of an area being traversed by the aircraft such that a current relative position of the aircraft is maintained proximate a center of the display, a first overlay on the moving map display that is indicative of a predetermined track of travel, and a second overlay on the moving map display indicative of a distance range from a suitable alternate airport. The second overlay also displays equal time points to assist flight crews in determining closest suitable alternate airport in the event of a required diversion. Constraints regarding the intended flight route on the organized track system are available for display to the flight crew.
