The course of an aircraft with respect to the true North is 120 degree, its course with respect to the magnetic North is 122 degree. Determine the magnetic variation at this location (in degrees).
To determine the magnetic variation, we need to find the difference between the true North and the magnetic North at this location.
The magnetic variation can be calculated by subtracting the course with respect to the magnetic North from the course with respect to the true North:
Magnetic Variation = True North Course - Magnetic North Course
Given:
True North Course = 120 degrees
Magnetic North Course = 122 degrees
Magnetic Variation = 120 - 122
Magnetic Variation = -2 degrees
Therefore, the magnetic variation at this location is -2 degrees.
To determine the magnetic variation at a specific location, you need to find the difference between the true North and magnetic North. This difference is known as the magnetic variation or declination.
In this case, the course of the aircraft with respect to true North is given as 120 degrees, and its course with respect to magnetic North is given as 122 degrees. The difference between these two courses represents the magnetic variation at that location.
To calculate the magnetic variation, subtract the course with respect to true North from the course with respect to magnetic North:
Magnetic Variation = Course with respect to magnetic North - Course with respect to true North
Magnetic Variation = 122 degrees - 120 degrees
Magnetic Variation = 2 degrees
Therefore, the magnetic variation at this location is 2 degrees.
The magnetic variation at a location is the angular difference between the true North and the magnetic North at that location. To determine the magnetic variation, we need to subtract the course with respect to the true North from the course with respect to the magnetic North.
Magnetic Variation = Course with respect to Magnetic North - Course with respect to True North
Magnetic Variation = 122 degrees - 120 degrees = 2 degrees
Therefore, the magnetic variation at this location is 2 degrees.
