Methods and systems for displaying a vertical profile for an aircraft procedure with nonuniform scaling
First Claim
1. A method for presenting procedure information for a vertical profile of an aircraft action comprising a plurality of navigational segments on a display device associated with an aircraft, the method comprising:
- displaying a first navigational segment of the plurality of navigational segments with a vertical scale and a first horizontal scale, the first horizontal scale being based on a first distance associated with the first navigational segment and first horizontal dimensions of the first navigational segment on the display device, the first distance being equal to a first ground distance between a first navigational reference point and a second navigational reference point defining the first navigational segment; and
displaying a second navigational segment of the plurality of navigational segments with the vertical scale and a second horizontal scale, the second horizontal scale being based on a second distance associated with the second navigational segment and second horizontal dimensions of the second navigational segment on the display device, the second distance being equal to a second ground distance between the second navigational reference point and a third navigational reference point defining the second navigational segment, wherein the first horizontal scale and the second horizontal scale are not equal.

Abstract
Methods and systems are provided for presenting procedure information for a vertical profile on a display device associated with an aircraft. A method comprises displaying a first segment of the plurality of segments comprising a vertical profile with a first vertical scale and a first horizontal scale, wherein the first horizontal scale is based on a first distance associated with the first segment. The method further comprises displaying a second segment of the plurality of segments with the first vertical scale and a second horizontal scale, wherein the second horizontal scale is based on a second distance associated with the second segment. The first horizontal scale and the second horizontal scale are not equal. In this manner, the vertical profile has a nonuniform horizontal scale and a uniform vertical scale across segments.

9. A method for presenting procedure information for an aircraft action between a first navigational reference point and a second navigational reference point on a display device associated with an aircraft, the method comprising:
-
rendering a vertical profile for the aircraft action on the display device, wherein the vertical profile is rendered with a uniform vertical scale and a nonuniform horizontal scale; and rendering a graphical representation of the aircraft on the display device within the vertical profile, wherein the graphical representation of the aircraft is positioned within the vertical profile based on the nonuniform horizontal scale and the uniform vertical scale such that the graphical representation of the aircraft accurately reflects an instantaneous position of the aircraft. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
