Abstract:
1. A head-up display scenery alignment system, said head-up display being mounted in an aircraft and including an image projector and a combiner, the combiner optically located between a user and a scenery of interest, optically transmitting a scene image of the scenery of interest to the user, the image projector projecting an image toward the combiner, the combiner reflecting the image toward the user, the aircraft including a heading angle sensor, determining the heading angle of the aircraft, the HUD scenery alignment system comprising: a moving mechanism coupled with said combiner; and a processor coupled with said heading angle sensor, with said moving mechanism and with said projector, said processor receiving heading angle information from said heading angle sensor, said processor determining the deviation of the heading of the aircraft from the longitudinal axis of the aircraft according to said heading angle information, wherein said processor directs said moving mechanism, according to said deviation, to move said combiner to a position which is located between said scenery of interest and said user and which aligns the reflection of said image toward said user, with said scene image.
