The HSI provides a basic horizontal view of the aircraft's navigation picture by displaying bearing and distance to a navigation aid, magnetic heading, track/ track deviation and course/course deviation.
 
The HSI is located in the Forward Centre Console.
 
Vertex Count: 56.879
Poly Count: 55.885
 
The model was made, textured, rigged and animated in Blender 2.79

Note: because of the instrument's complexity, it has a high level of poly counts. It's worth noting that I have tried to keep it as low as possible but yet maintaining all it's features, components and indicator's fidelity and realism.
