What is the default page displayed on the GPS?

The correct answer is that the default page displayed on the GPS is the MAP. The MAP page provides a visual representation of the aircraft's position relative to surrounding terrain, waypoints, and airways. It serves as a crucial tool for navigation, allowing pilots to see their route, any nearby navigation aids, and any relevant airspace information.

While different pages like NAV 1, NAV 2, and FLIGHT PLAN may contain important navigational data, they are not the primary interface that pilots interact with immediately upon activation of the GPS. The MAP page is designed to be the most intuitive and user-friendly display, ensuring that pilots have quick access to essential navigation information as soon as the system is powered on.
