What does Azimuth mean?

• A. The distance of an object from an observer
• B. The vertical angle of the aircraft relative to the horizon
• C. Angular position or bearing in a horizontal plane usually measured clockwise from true north
• D. The rate of change of bearing to a moving target

Answer: (C)

Azimuth is the horizontal angle that describes the direction to something in the plane parallel to the ground. It’s the bearing measured clockwise from true north, so 0 degrees is north, 90 is east, 180 is south, and 270 is west. This tells you where to look or point in the horizontal direction, independent of distance or height. In practice, some systems use magnetic north as the reference, so azimuth can be relative to magnetic north instead of true north; you’d convert between the two when needed.
