- An instrument which senses airplane movement and displays heading based on a 360° azimuth, with the final zero omitted.

- Contexto
- In coordinated flight, the heading indicator gives an indirect indication of the helicopter ’s bank attitude. When a helicopter is banked, it turns. When the lateral axis of the helicopter is level, it flies straight. Therefore, in coordinated flight, when the heading indicator shows a constant heading, the helicopter is level laterally.
