What should you do if your current range scale is too large, resulting in less detail?

• A. Switch to a smaller scale to show more detail.
• B. Increase radar power.
• C. Change to a larger range scale for more area.
• D. Turn off radar.

Answer: (A)

When you want more detail on the radar screen, you need to adjust the range so the picture is magnified. The range scale determines how far out the display covers. If the scale is too large, you’re showing a lot of area, so each target takes up fewer pixels and fine detail is lost. By selecting a smaller range scale, you limit the display to a closer span. That concentrates the screen real estate on the near area, making targets and features appear larger and more defined.

Increasing radar power won’t inherently zoom the display or add detail in the near field, it mainly extends detection range and signal strength. Switching to a larger range scale would show more area but reduce detail, not improve it. Turning off radar would remove the display altogether. So the best step to gain more detail when the current range is too large is to switch to a smaller scale.
