Abstract: A display system and method for an aircraft simultaneously displays the terrain under the flight plan, or under the current track of the aircraft, as both a two-dimensional lateral situation view image and as a perspective vertical situation view image. This provides improved tactical flight planning, and that does not erroneously show the flight plan passing through the displayed terrain.

Abstract: Methods and systems for displaying a digital terrain to a user of a vehicle are provided. First, second, and third actual terrain data points are received. The third actual terrain data point is between the first and second actual terrain data points. If the third actual terrain data point is above a line interconnecting the first and second actual terrain data points, the first actual terrain data point is modified such that the third actual terrain data point is not above a line interconnecting said modified first actual terrain data point and the second actual terrain data point. A digital terrain is displayed to the user of the vehicle. The digital terrain includes a first digital terrain data point corresponding to the modified first actual terrain data point.

Abstract: An avionics system includes a display device that is viewable by a user of an aircraft and a processor in operable communication with the display device. The processor is configured to display a digital terrain having a digital landmark thereon on the display device, the digital terrain being representative of an actual terrain and the digital landmark being representative of an actual landmark on the actual terrain, and display a plurality of position indicators over the digital terrain such that a line extending through the plurality of position indicators intersects the digital landmark, the position indicators being a fixed digital terrain distance apart as measured over the digital terrain.

Abstract: A vertical situation display (“VSD”) system according to the invention generates a terrain image that represents a profile view of terrain elevation relative to the position of an aircraft traveling above the terrain. The VSD system generates the VSD image such that the terrain image is biased toward the lower elevation region of the VSD screen, thus making efficient use of the available display area. The VSD image is also generated such that it is continuous across the lateral range of the VSD, thus ensuring that terrain is shown in the VSD at all practical times, depending upon the available range and any priority display rules.
