Methods and systems for route-based scrolling of a navigational map

摘要

Methods and systems are provided for indicating the relationship of a displayed area (516) on a map (300) with respect to a route or flight plan (306). A method comprises displaying a navigational map (300) on a display device (102) and displaying a graphical adjustment element (318) on the display device (102). The position of the graphical adjustment element (318) on the display device (102) corresponds to the along track distance between the displayed area (516) of the navigational map (300) and a first navigational reference point (502) of a route comprising the first navigational reference point (502) and a second navigational reference point (512).
