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).
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.
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.
The magnetic variation is the angle between true North and magnetic North at a specific location. It changes depending on the location and year.
In this case, the course with respect to true North is given as 120 degrees, and the course with respect to magnetic North is given as 122 degrees.
To find the magnetic variation, we 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
= 122 degrees - 120 degrees
= 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 the magnetic North at that location.
In this case, you are given the course of the aircraft with respect to both the true North and the magnetic North. The difference between these two courses will give you the magnetic variation.
The formula to calculate the magnetic variation is:
Magnetic Variation = Course with respect to True North - Course with respect to Magnetic North
Using the given values, we can substitute them into the formula:
Magnetic Variation = 120 - 122 = -2
Therefore, the magnetic variation at this location is -2 degrees.
