Weather radar can display in all ND modes except the ____ mode.

Weather radar can display in all ND modes except the ____ mode.

• A. Auto
• B. Plan
• C. Map
• D. Weather

Answer: (B)

Weather radar is an extra data layer for the Navigation Display that can be shown in modes used for actual navigation and weather awareness. Plan mode is dedicated to preflight and en-route planning, focusing on the route, waypoints, distances, and ETAs. Mixing in real-time radar data would clutter the planning view and could confuse planning decisions, so the radar overlay isn’t available in this mode. In the other ND modes, the radar can be displayed to give the crew current weather information while navigating. Auto, Map, and Weather modes all support showing the radar imagery alongside navigation data, helping pilots assess weather while following the route.
