CORRECT!

1). The magnetic heading is 350° and the relative bearing to a radiobeacon is 240°. What would be the magnetic bearing TO that radiobeacon?

a). 050°.
b). 230°.
c). 295°.
The answer is:
b). 230°.

The simple way to figure out the correct answer to Automatic Direction Finder (ADF) / Non-Directional Beacon (NDB) problems is to use the following formula:

Magnetic Heading (MH) + Relative Bearing (RB) = Magnetic Bearing (MB).
[Most of us learned the mnemonic 'Mary Had Roast Beef, Mary Barfed' to help to remember the formula!]

Look at a compass rose and find the 350° mark, then count 240° clockwise around the face of the compass. You should arrive at the 230° indicator.

Applying this formula allows us to figure out the correct answer to test questions, but it obviously leaves us with an incomplete understanding of ADF / NDB navigation. The relative bearing simply represents the number of degrees of heading change required to place the aircraft on the given magnetic bearing TO the station.

In future Aviation Quizzes, we will delve into the intricacies of NDB navigation, explaining how to go about intercepting a given magnetic bearing to the station. But, alas, this is subject matter better presented in a quiz based on the FAA Instrument rating, so it will have to wait...
