ABSTRACT:
An aircraft display system has a display unit comprising a matrix array of LED's mounted in the glareshield. Air traffic command signals received by a datalink processor produce a visual indication on the display unit which is visible to the pilot when looking through the window. A button on the display unit is pressed by the pilot to acknowledge receipt of instructions. Other important messages are displayed by the display unit at different times. Radar altimeter height is displayed in a color which changes when the aircraft descends below its flare height. When on the ground, the display unit displays alphanumerically the distance-to-go to the end of the runway, and simultaneously displays stripes that move horizontally to indicate deviation of the aircraft from the runway center line.
