1. 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.

20. 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.
