Abstract
A display system for an aircraft is provided. The display includes a processing unit configured to receive terrain data and navigation data and to supply display commands with symbology based on the terrain data and navigation data; and a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view with the symbology. The symbology includes terrain, a zero pitch line, and elevation symbology indicating a relative elevation between the zero pitch line and a position in the view.

A display system for an aircraft, comprising:
- a processing unit configured to receive terrain data and navigation data and to supply display commands with symbology based on the terrain data and navigation data;
- and
- a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view with the symbology, the symbology comprising terrain, a zero pitch line, and elevation symbology indicating a relative elevation between the zero pitch line and a position in the view.
A method for displaying symbology on a Primary Flight Display (PFD) of an aircraft, comprising:
- displaying a synthetic 3D view of terrain that includes a zero pitch reference line, wherein the terrain includes a first position with an elevation;
- and
- displaying symbology in the view indicating the elevation at the first position relative to the zero pitch reference line.
A Primary Flight Display system for an aircraft, comprising:
- a processing unit configured to receive terrain data and navigation data and to supply display commands with symbology based on the terrain data and navigation data;
- and
- a display device coupled the processing unit and configured to receive the display commands and operable to render a three-dimensional view with the symbology, the symbology comprising terrain, a zero pitch line, and elevation symbology including a plurality of drop lines, wherein the drop lines include a first drop line to a high point within the terrain above the zero pitch reference line, a second drop line a high point within the terrain below the zero pitch reference line, a third drop line to a low point within the terrain, and a fourth drop line to a landing area.
