ABSTRACT:
A display head for a head-up display system for use in a confined space, such as a high performance aircraft cockpit. The display head has a first part (11, 13, 23, 25) adapted to be mounted on an overhead member and the remainder (15, 21, 28, 29, 31) of the display head is pivotally mounted on the first part so as to enable it to be moved readily between operative and stowed positions. In the stowed position the display head does not obstruct movement of the user's head or present an obstruction on which the user may strike his head.
