1. A method comprising:
- displaying a navigational map on a display device, the navigational map having a displayed area;
displaying a graphical adjustment element on the display device, wherein;
a position of the graphical adjustment element on the display device corresponds to an along track distance between the displayed area and a first navigational reference point of a route;
the route comprises the first navigational reference point and a second navigational reference point; and
the along track distance is measured along the route; and
displaying a vertical profile on the display device, the vertical profile corresponding to the displayed area, wherein the vertical profile is automatically adjusted to correspond to a portion of the route within the displayed area in response to an adjustment of the position of the graphical adjustment element.

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

5. A method comprising:
-
displaying a navigational map on a display device, the navigational map having a displayed area; displaying a graphical adjustment path on the display device, the graphical adjustment path corresponding to a first along track distance between a first navigational reference point of a route and a second navigational reference point of the route, the graphical adjustment path being displayed with a first number of pixels; identifying a point within the route that corresponds to the displayed area; calculating a second along track distance from the point to the first navigational reference point to obtain the second along track distance between the displayed area and the first navigational reference point; determining a position of a graphical adjustment element based on a ratio of the second along track distance between the displayed area and the first navigational reference point to the first along track distance between the first navigational reference point and the second navigational reference point, wherein determining the position of the graphical adjustment element comprises; determining a scale of the graphical adjustment path based on a ratio of the first number of pixels to the first along track distance between the first navigational reference point and the second navigational reference point; and calculating a second number of pixels based on the second along track distance between the displayed area and the first navigational reference point and the scale of the graphical adjustment path; and displaying a graphical adjustment element on the display device overlying the graphical adjustment path at the position corresponding to the second number of pixels, such that the position of the graphical adjustment element with respect to the graphical adjustment path corresponds to the second along track distance between the displayed area and the first navigational reference point.

10. A method comprising:
-
displaying a navigational map on a display device, the navigational map having a displayed area; displaying a graphical representation of a portion of a flight plan on the navigational map within the displayed area, the flight plan having a first navigational reference point and a second navigational reference point; displaying a vertical profile of the portion of the flight plan on the display device; displaying a graphical adjustment element on the display device, wherein a position of the graphical adjustment element on the display device corresponds an along track distance between the displayed area and the first navigational reference point of the flight plan; and adjusting the vertical profile of the flight plan in response to an adjustment of the position of the graphical adjustment element. - View Dependent Claims (15, 16)
