- The course deviation indicator (CDI) is found in most training aircraft.
- It consists of an omnibearing selector (OBS), sometimes referred to as the course selector; a CDI needle (left-right needle); and a TO/ FROM indicator.
- The course selector is an azimuth dial that can be rotated to select a desired radial or to determine the radial over which the aircraft is flying.
