Methods and systems for displaying enroute moving maps
First Claim
1. A position indicating display system for an aircraft comprising:
- a moving map display screen representative of an area being traversed by the aircraft such that a current relative position of the aircraft is maintained within a margin of the screen wherein said moving map display is configurable in at least one of a north-up and a heading-up orientation mode;
a first overlay on the moving map display that is indicative of at least one of a predetermined track of travel and a predetermined routea second overlay on the moving map display indicative of a distance range of travel of the aircraft from a facility capable of receiving the aircraft; and
a third overlay on the moving map display indicative of a time range of travel of the aircraft from the facility, wherein the distance range of travel and the time range of travel are determined using the current rate of travel of the aircraft over the round and a predetermined time period, and wherein said second overlay and said third overlay are alternatively selectable for display on the moving map display.

Abstract
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.

15. A method of displaying a current position of an aircraft comprising:
-
determining a current position of the aircraft; displaying a moving map of an area of earth surface surrounding the determined current position of the aircraft wherein a size of the area is selectable by a user; displaying a predetermined track of intended travel across the area; and displaying one of a second overlay and a third overlay on the moving map display, wherein the second overlay is indicative of a distance range of travel of the aircraft from a facility capable of receiving the aircraft, and the third overlay is indicative of a time range of travel of the aircraft from the facility, wherein the distance range of travel and the time range of travel are determined using the current rate of travel of the aircraft over the ground and a predetermined time period wherein the second overlay and the third overlay are alternatively selectable for display on the moving map display, and wherein said moving map display is configurable in at least one of a north-up and a heading-up orientation mode. - View Dependent Claims (16, 17, 18)

19. An electronic flight bag system including a moving map display comprising:
-
a first overlay displayed on the moving map display indicative of an intended track of travel a second overlay displayed on the moving map display indicative of a current position of the aircraft and further indicative of a distance range of travel of the aircraft with respect to a position of a plurality of facilities capable of receiving the aircraft; and a third overlay displayed in the moving map display indicative of the current position of the aircraft and further indicative of a time range of travel of the aircraft with respect to the position of the plurality of facilities wherein the distance range of travel and the time range of travel are determined using the current rate of travel of the aircraft over the ground and a predetermined time, and wherein said second overlay and said third overlay are alternatively selectable for display on the moving map display. - View Dependent Claims (20, 21, 22)
