In _____ resolution, the radar can cause interference with FAA ground radars. Operators shall not use _____ resolution while the aircraft is overland and towards land if within 70 NM due to national telecommunications and information administration restrictions. The radar software is designed to prevent this selection in these areas as long as the radar maps are loaded.

• A. 1/2 Meter
• B. 1/4 Meter
• C. 1 Meter
• D. 2 Meter

Answer: (A)

The question tests understanding of regulatory limits on radar map resolution to prevent interference with FAA ground radars. Within 70 nautical miles of land, NTIA restrictions limit the use of high-detail radar mapping, and the system is designed to automatically block that option when radar maps are loaded so you stay compliant.

The reason the correct choice is the 1/2 meter resolution is that this level of detail is the one specifically associated with the interference risk described in the rule. The radar software prevents selecting that resolution in overland directions within 70 NM, provided the radar maps are loaded, to avoid disrupting ground radar operations.

The other resolutions are either coarser or finer than this specific restricted setting, and the statement points to 1/2 meter as the resolution tied to the restriction in this context.
