The course of an aircraft with respect to the true North is 120, its course with respect to the magnetic North is 122. Determine the magnetic variation at this location (in degrees).

Answer 1

To determine the magnetic variation at this location, we need to find the difference between the course with respect to true North and the course with respect to magnetic North.

Magnetic variation = True course - Magnetic course

Magnetic variation = 120 - 122 = -2 degrees

Therefore, the magnetic variation at this location is -2 degrees.
