What will happen to the bearing pointer on the MFD if there is a signal loss?

• A. The respective pointer will be removed from view
• B. It will lock to the last known bearing
• C. It will switch to GPS mode
• D. It will display a dashed line

Answer: (A)

When the navigation signal is lost, the MFD removes the bearing pointer because the data driving that pointer is no longer valid. The pointer only appears when a live, trustworthy input is available, so blanking it prevents you from acting on stale or misleading information. It won’t stay on the last known bearing, won’t automatically switch to GPS for that bearing, and won’t show a dashed line as a substitute—those options would imply there’s usable data or a different display mode, which isn’t the case during a signal loss. Once the signal is reacquired or an alternative source is engaged, the bearing pointer will reappear and provide current guidance.
