ABSTRACT:
An aircraft collision avoidance instrument system has a display located in the aircraft glareshield in the peripheral field of view of the pilot when the pilot is looking forwardly through the aircraft window. The display has a matrix array of LCD elements which is controlled to provide a continually changing image that is visible in the peripheral field of view of the pilot when a possible collision with another aircraft is likely. The changing image may be arrows moving up or down the display to indicate climb or decend, or a flashing horizontal line to indicate that present height must be maintained. An alphanumeric legend indicative of the collision avoidance action to be taken is also provided by the display. When no collision is likely, the display is used to present other information to the pilot.
