Abstract:

An experimental cockpit mounted head-up type display system has been developed and evaluated by LaRC pilots during the landing phase of light aircraft operations. The Landing Site Indicator LASI system display consists of angle of attack, angle of sideslip, and indicated airspeed images superimposed on the pilots view through the windshield. The information is made visible to the pilot by means of a partially reflective viewing screen which is suspended directly in front of the pilots eyes. Synchro transmitters are operated by vanes, located at the left wing tip, which sense angle of attack and sideslip angle. Information is presented near the center of the display in the form of a moving index on a fixed grid. The airspeed is sensed by a pitot-static pressure transducer and is presented in numerical form at the top center of the display. Display systems, Landing site indicator, Landing aid, Head-up display, Angle of attack.
