A radar display which is oriented so that north is always at the top of the screen is called a(n) __________.

A radar display that maintains a constant orientation with north always at the top of the screen is known as a stabilized display. This ensures that regardless of the vessel’s heading or movement, the display remains fixed, allowing for easier interpretation of navigational information and situational awareness. This configuration is particularly useful in situations where the user must consistently reference geographic features or other vessels, making it easier to identify and assess relative positions and movements.

In contrast, relative displays would show the vessel's position at the center and rotate the display as the vessel turns, which can be less intuitive when trying to relate to stationary landmarks. Composite displays might integrate various types of data but do not inherently refer to the specific orientation where north is stable at the top. Unstabilized displays, on the other hand, do not maintain any fixed orientation, which adds complexity to navigation and requires the navigator to constantly adjust their understanding based on the vessel’s movements. Thus, the term "stabilized display" accurately describes the functionality of a radar display oriented with north at the top.
