Abstract:
1. A display system for an aircraft, comprising: a processing unit configured to determine a visual segment for the aircraft and to generate display commands based on the visual segment, wherein the visual segment is a two dimensional geographical area on the ground at a predetermined location and defined with a rectangular construction with a predetermined length and a predetermined width; and a display device coupled the processing unit and configured to receive the display commands and to display symbology representing the visual segment as a visual segment marker, wherein, during a landing situation at a runway, the processing unit is further configured to determine runway references associated with the runway that are within the visual segment, wherein the display commands are further based on the runway references, and wherein the display device is further configured to display symbology representing the runway references as runway reference markers, wherein the visual segment marker is rendered as an outline on the display device with the generally rectangular construction according to the predetermined length and the predetermined width, and wherein the runway references are rendered within the outline of the visual segment marker, wherein the processing unit is additionally configured to display runway references associated with the runway that are outside of the visual segment, wherein the display device is configured to highlight the runway references inside the outline of the visual segment relative to runway references outside the outline of the visual segment marker, wherein the visual segment is defined according to Federal Aviation Administration (FAA) regulation as a function of aircraft position, the visual segment marker having a forward boundary defined at a predetermined distance from the aircraft, and wherein the visual segment has a length of between about 60 meters and about 90 meters.
