When a DME-equipped navigation facility is tuned, the DME distance to that facility is displayed in which of the following?

• A. The PFD source data block if the source is selected to VOR or LOC
• B. The bearing pointer data blocks on the PFD and NAV displays if VOR or LOC is the selected bearing source
• C. The DIST data field at the top of the NAV display
• D. Both A and B

Answer: (D)

DME distance readouts are shown in multiple places when a DME-equipped facility is tuned. If VOR or LOC is the active source, the DME distance to that facility appears in the PFD’s source data block. If VOR or LOC is also the selected bearing source, the bearing pointer data blocks on the PFD and NAV displays will also display that DME distance. Since both locations can show the DME distance, the best answer is that it appears in both.
