Guidance Controller Course and Heading Controls
The course pointer and heading bug are controlled using the guidance
controller course (CRS) and heading (HDG) knobs, shown in figure
4--18. The heading knob controls the heading bug on both sides of the
cockpit (HSI/MFD). The onside course knob controls the onside course
pointer when the NAV (VOR/LOC) is the selected navigation source.
Additional information on the guidance controller is given in Section 6,
Flight Guidance System (FGS).
