A symbology system uses programmable software in a computerized system interacting with the altitude, attitude, air speed, and other flight indicators of an aircraft to create symbology in the pilot's display seen in the field of view of the pilot. The symbology represents a virtual geometric solid form, such as a vertical cylinder, always appearing perpendicular to the horizon and moving across the terrain with the aircraft in the center of the form. The pilot sees a front portion of a virtual series of horizontal circles or other shapes, spaced by a programmable distance, symbolizing the geometric solid form appearing to surround the aircraft. The geometric form references the world as-ground for use in recognizing the attitude of the aircraft-as-figure. On landing, the form appears to stop at the ground and the aircraft appears to descend within it. A virtual bank indicator line changes orientation to the geometric solid corresponding to the attitude change of the aircraft relative to the horizon.
