ABSTRACT:
A navigation aid device for use when a predetermined route is followed, said route extending from a starting point along a series of break points up to a destination being the last break point. The device comprises an elongated course indication unit extending on either side of a fixed center point and indicating any necessary course adjustments by displacing an appearance pattern to the left or to the right relative the center point. A distance indication unit indicates how far it is up to the next break point. A central area in the appearance pattern is shown relatively wide in the course indication unit when greater course deviations can be tolerated, and is shown narrower when the course must be kept more precisely.
