On a north-up stabilized radar display, the top of the screen always represents:

- DThe course made good
Explanation
North-up uses a gyro input so the top of the display is always true north; the heading marker rotates as the ship yaws. Head-up puts the heading at the top, and course-up freezes the set course at the top.
