A Magnetic Bearing is a navigation tool used in maritime and shipping industries to determine a ship's direction relative to magnetic north. Think of it like a more advanced compass reading that helps navigation officers determine their position and plan routes at sea. It's different from a True Bearing because it refers to the angle between the ship's direction and magnetic north, rather than geographic north. When you see this term on a resume, it usually indicates that the candidate has experience with navigation equipment and understands maritime direction-finding techniques.

Q: Describe your experience training junior officers in navigation techniques.
Expected Answer: Should demonstrate leadership experience, ability to teach fundamental navigation concepts, and explain how they ensure safety standards are maintained while training others.
Q: How do you verify the accuracy of magnetic bearing readings?
Expected Answer: Should explain the process of cross-checking with other navigation tools, using multiple reference points, and regular equipment calibration procedures.
Q: What factors can affect magnetic bearing accuracy?
Expected Answer: Should mention environmental conditions, nearby metal objects, electronic interference, and explain how to compensate for these factors.
Q: What is the difference between magnetic bearing and true bearing?
Expected Answer: Should be able to explain that magnetic bearing is relative to magnetic north, while true bearing is relative to geographic north, and understand basic conversion between the two.
Q: How do you take a basic magnetic bearing reading?
