Which mode provides similar information as the ARC mode, but is displayed on a full compass rose?

• A. Nav
• B. ARC
• C. PLAN
• D. ROSE

Answer: (B)

The main idea here is how the Navigation Display can present orientation and navigation data. ARC mode shows a circular map centered on the aircraft with a local arc view of the surroundings. It gives you the same kind of route and bearing information, but limited to a portion of the circle. ROSE mode does the same job of conveying that navigation data, but it places everything on a full compass rose around the aircraft, giving you a 360-degree reference and clear bearings relative to north. That full rose makes it easier to read headings and verify direction at a glance, which is why it’s the mode that corresponds to having ARC information displayed on a complete compass rose. NAV and PLAN display different perspectives: NAV is a standard map view of the route, while PLAN is a plan/overview view for planning, not the 360-degree rose orientation.
