ABSTRACT:
A head-up display for indicating the attitude and flight-path angle vertically, the attitude in roll and preferably the heading attitude and heading track angle of a vehicle, preferably an air vehicle, which in addition to the inertial navigation (5) for determining said attitudes and angles comprises a transparent but partly reflecting plate (10), a so-called "combiner glass" glass for projecting a corresponding display together with at least one symbol (14) of the x-axis of the vehicle. Particularly characteristic is that the head-up-display is arranged to show the display (12) as at least a portion of the inside of a space-stable sphere with its center in said vehicle, the display being provided with latitude circles (15, 16, 19, 20) and preferably meridian markings (18).
