The Horizontal Situation Indicator (HSI) combines which two functions?

Explanation:
The Horizontal Situation Indicator combines heading information with navigation course information in one view. It shows your current magnetic heading on a rotating compass card and, superimposed on that, the course deviation indicator that tells you how far off you are from the selected VOR/localizer course. The CDI deflects left or right to guide you back to the desired track, while the heading shows where you’re pointing. This integrated display lets you intercept and track a course efficiently without switching between separate instruments. The other options pair instruments that don’t provide both heading and course deviation in one instrument.
