Multiple Choice

A radar display with North always at the top is best described as what type of display?

Keeping geographic north at the top creates a North-Up radar display. In this setup, the top of the screen always represents north, giving you a fixed geographic frame of reference for bearings and directions. This makes it easy to relate targets to compass directions and chart data, regardless of your ship’s heading. It’s different from a stabilized display, which rotates with your heading so north isn’t fixed at the top, and from true motion or relative motion displays, which describe how targets move on the screen rather than how the screen itself is oriented.
