If you measure an Azimuth of 213.2 with a magnetic compass, and the Magnetic Declination of your location is 7.2 degrees East, what is the True Azimuth (report in numerical DD format, with no units)
Question
If you measure an Azimuth of 213.2 with a magnetic compass, and the Magnetic Declination of your location is 7.2 degrees East, what is the True Azimuth (report in numerical DD format, with no units)
Solution
To calculate the True Azimuth, you need to adjust the Magnetic Azimuth by the Magnetic Declination.
Here are the steps:
- Identify the Magnetic Azimuth: 213.2 degrees
- Identify the Magnetic Declination: 7.2 degrees East
- Since the Magnetic Declination is East, you subtract it from the Magnetic Azimuth. If it was West, you would add it.
So, the calculation is:
213.2 degrees (Magnetic Azimuth) - 7.2 degrees (Magnetic Declination) = 206 degrees
So, the True Azimuth is 206 degrees.
