Abstract

Head-up display scenery alignment system, the head-up display being mounted in an aircraft and including an image projector and a combiner. The combiner is 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 projects an image toward the combiner, and the combiner reflects the image toward the user. The aircraft includes a heading angle sensor, determining the heading angle of the aircraft. The HUD scenery alignment system includes a moving mechanism coupled with the combiner; and a processor coupled with the heading angle sensor, with the moving mechanism and with the projector. The processor receives heading angle information from the heading angle sensor, and the processor determines the deviation of the heading of the aircraft from the longitudinal axis of the aircraft according to the heading angle information. The processor directs the moving mechanism, according to the deviation, to move the combiner to a position which is located between the scenery of interest and the user and which aligns the reflection of the image toward the user, with the scene image.
