electronic attitude directional indicator, EADI
A multicolor cathode-ray-tube display of attitude (angle of an aircraft) information, roll and pitch, showing the aircraft's position in relation to the instrument landing system or a very high-frequency omnirange station.

The term omnirange refers to a radio aid to navigation which provides a direct indication of the magnetic bearing (omnibearing) of that station from any direction.
