Which selectors allow displaying VOR or ADF bearing on the ND (except PLAN mode)?

• A. ADF-VOR selectors
• B. ND mode selector
• C. CRS selector
• D. PFD mode

Answer: (A)

The ability to show VOR or ADF bearing on the navigation display is controlled by the ADF-VOR selectors. When you tune or select a VOR or ADF on those selectors, the ND is wired to display the bearing to that station, giving you the VOR/ADF bearing on the display in modes other than PLAN. The other selectors don’t enable that bearing display: the ND mode selector only changes how the map is presented (MAP, ARC, ROSE, etc.), the CRS selector sets a reference course for navigation cues but doesn’t activate VOR/ADF bearing display, and the PFD mode affects the primary flight display, not the ND bearing pointers.
