Displays and display systems.

摘要

An aircraft display system has a display unit 4 with matrix array of LED's 40 mounted in the glareshield 5. Air traffic command signals received by a datalink processor 2 produce a visual indication on the display unit 4 which is visible to the pilot when looking through the window 50. A button 41 on the unit 4 is pressed by the pilot to acknowledge receipt of the instructions. Other important messages are displayed by the unit at different times. Radar altimeter height is displayed in one colour which changes when the aircraft descends below its flare height. When on the ground, the unit 4 displays the distance-to-go to the end of runway, and stripes that move horizontally along the display unit to indicate deviation from the runway centre line. <IMAGE>
