During GPS signal loss, how does the bearing pointer on the MFD respond?

• A. It remains visible
• B. The bearing pointer is removed from view
• C. It switches to a dashed line
• D. It displays last known bearing

Answer: (B)

When GPS data is no longer available, the bearing pointer is removed from view. This pointer depends on live GPS information to show the direction to a waypoint or destination. If GPS data is lost, the bearing would be invalid or misleading, so the system hides it to prevent pilots from acting on inaccurate information. You would rely on other navigation sources (like VOR, VOR/DME, or dead reckoning) until GPS is restored. The display doesn’t keep showing a last known bearing or switch to a dashed line in this design, because that could imply ongoing accuracy when the data isn’t valid.
