Abstract
A display apparatus includes an image source displaying information and a magnifying mirror element reflecting the displayed information and projecting one or more images thereof viewable by the operator in one or more focal planes, the mirror element being partially light transmissive. A display data source is also provided so that, in a first mode, the display data is not visible and in a second mode the display data is visible to the operator through the mirror. A motor mechanism is operable to pivot the display between a stowed position and an unstowed operational position.
