Question 8-34D5
Element 8 (RADAR)Which of the following statements about “true bearing” is correct?
Explanation
A true bearing display, often found on radar or electronic chart systems, orientates the screen so that **True North is always at the top**. This provides a fixed, geographic reference for all measurements.
Therefore, statement B is correct: "True North is at the top of the screen and the heading flasher indicates the vessel’s course." The heading flasher is a line extending from the center of the display, indicating your vessel's current bow direction relative to True North.
* **A) The ship’s heading flasher is at the top of the screen.** This describes a "Head Up" display, where the vessel's bow is always pointing to the top, and the display rotates as the vessel turns. This is characteristic of *relative* bearing, not true bearing.
* **C) The true bearing of the nearest target is indicated.** While a true bearing display *can* indicate the true bearing of a target, this statement describes a specific measurement rather than the fundamental orientation of the display itself.
* **D) The relative bearing of the nearest target is indicated.** Relative bearings are measured relative to the ship's bow, which is not the defining characteristic of a true bearing display.
