Which of the following describes True Motion mode?

• A. The own ship stays in the center, other contacts move in relation to own ship
• B. The own ship will move across the screen as it is actually moving
• C. A user-directed graphical line tool to indicate or measure a bearing on the radar display
• D. A user-directed graphical circle tool to indicate or measure a range on the radar display

Answer: (B)

True Motion mode shows targets moving with their actual motion relative to the earth, so the own ship is not fixed on the display. Instead, the own ship symbol moves across the screen in accordance with its real movement. This allows you to see true speeds and directions of other vessels, helping to assess collision risk and relative motion in a way that reflects actual movement of the ships, rather than imagining the own ship is stationary.

In contrast, relative motion keeps your own ship fixed at the center and makes all other targets drift around it as if the ship were stationary. The other options describe measurement tools (bearing or range) rather than motion modes, so they don’t describe True Motion.
