Which statement recognizes Heading-up orientation?

• A. North-up rotates with the ship's heading.
• B. Course-up rotates with the ship's heading.
• C. Heading-up rotates with the ship's heading.
• D. All orientations rotate with the ship's heading.

Answer: (C)

Heading-up orientation keeps the display tied to the vessel’s actual heading, so as the ship turns, the image rotates to keep the ship’s heading at the top of the screen. This means the top of the display always points in the ship’s heading direction, which is exactly what heading-up describes. That’s why the statement about heading-up rotating with the ship’s heading is the best fit.

In contrast, north-up fixes true north at the top regardless of how the ship is pointing, so it does not rotate with the ship’s heading. Course-up rotates with the ship’s course over ground, which can differ from the ship’s heading due to drift from wind or current. Saying all orientations rotate with the ship’s heading would incorrectly imply north-up also rotates, which it does not.
