Multiple Choice

In the mnemonic, what term corresponds to Magnetic Heading?

The question tests remembering four ways we express a vessel’s heading and which term in the mnemonic represents Magnetic Heading. The mnemonic sequence is Gyro heading, True heading, Compass heading, Magnetic heading. The final item, represented by Magnetic Heading, is exactly the heading relative to magnetic north. A magnetic compass indicates this value, and you can convert it to true heading by applying variation and deviation as needed. The other terms refer to the other reference frames: the gyro heading comes from the gyro compass (closer to true north), the true heading is relative to true north, and the compass heading is the magnetic compass reading (relative to magnetic north).
