From the UFCP persistent display, which items can be viewed or changed?

• A. Barometric altimeter
• B. UHF communication frequency
• C. VHF communication frequency
• D. Both A and B

Answer: (D)

The UFCP persistent display is meant for quick access to a couple of critical items you’re likely to adjust during flight. It shows and lets you change the barometric altimeter setting (the QNH) because keeping the altitude reading accurate is essential and something pilots adjust as conditions change. It also allows viewing and changing the UHF radio frequency, which is a type of comms setting that may be updated for different missions or airspace requirements. The VHF frequency, while important, is typically controlled on a separate VHF radio interface rather than the UFCP persistent display, so it isn’t part of what you can view or change there. Therefore, the items you can view or change on the UFCP persistent display are the barometric altimeter setting and the UHF frequency.
