Aircraft landing display system
First Claim
1. A system for presenting a cockpit display providing guidance information for landing an aircraft on a runway in conditions of low visibility, comprising:
- a display device visible to the pilot;
means for generating on said display device a horizons reference line having a generally fixed horizontal configuration;
means for generating an aircraft symbol on said device, said aircraft symbol having an orientation with respect to said reference line corresponding to the orientation of the aircraft with respect to the actual horizon;
means for generating on said display device a runway symbol having an orientation with respect to the aircraft symbol indicative of the orientation of the actual runway with respect to the aircraft; and
means for generating a generally V-shaped descent profile vector extending from respective sides of the display towards a location on the projected flight path of the aircraft indicative of the projected landing point of the aircraft.

Abstract
A landing display system for indicating to the pilot of an aircraft the relationship between his aircraft and a landing runway includes an aircraft symbol providing attitude information with respect to a reference horizon, a velocity vector indicative of the projected flight path of the aircraft, a descent profile vector indicative of the projected descent path of the aircraft, and a runway symbol in perspective to the aircraft. By reference to these displays the pilot can ascertain not only the present position of his aircraft with respect to the runway, but also the consequences of various corrective maneuvers accomplished with the aircraft.

7. A blind landing display system for assisting the pilot of an aircraft in landing on a runway in poor visibility conditions, comprising:
-
a display device in view of the pilot; means for generating on said display device a horizon reference line having a generally fixed horizontal relationship with respect to said device; means for generating an aircraft symbol on said display device having an orientation with respect to said horizon reference line corresponding to the relationship between the aircraft and the actual horizon; means for generating a runway symbol on said display device below the horizon reference line having an orientation with respect to said aircraft symbol generally corresponding to the visual orientation of the actual runway as viewed from the aircraft, said runway symbol including an extended center line; means for generating a velocity vector extending from said aircraft symbol indicative of the projected flight path of the aircraft with respect to said extended center line; and means for generating a generally disjointed V-shaped descent profile symbol extending from either side of said display to indicate the projected landing point of the aircraft with respect to said runway. - View Dependent Claims (8, 9, 10, 11)
