AVIATION & AERONAUTIC CALCULATOR
Magnetic Heading
A precise tool.
What is the Magnetic Heading & How does it work?
The magnetic heading is the direction of an aircraft’s nose relative to magnetic north, which can differ from true north due to the Earth’s magnetic field. This difference is known as magnetic variation.
To calculate the magnetic heading from the true heading, you need to add the magnetic variation to the true heading. The formula for this calculation is:
text{Magnetic Heading} = text{True Heading} + text{Magnetic Variation}

Frequently Asked Questions
What is the difference between true heading and magnetic heading?
True heading is the direction relative to true north, while magnetic heading is the direction relative to magnetic north. The difference is called magnetic variation.
How do I calculate magnetic heading from true heading?
Add the magnetic variation to the true heading to get the magnetic heading.
Why is there a difference between true and magnetic headings?
The Earth’s magnetic field causes a difference between true north (geographic north) and magnetic north, resulting in magnetic variation.
Can you explain what magnetic variation is?
Magnetic variation is the angle between true north and magnetic north at a specific location. It varies depending on where you are on Earth.
How do I find my magnetic variation?
You can find your magnetic variation by checking aviation charts, using an online database like NOAA’s, or consulting aeronautical publications.
Is magnetic heading always different from true heading?
No, in some locations where magnetic north and true north align, the magnetic heading will be the same as the true heading.
How important is it to use magnetic heading for navigation?
It’s crucial for accurate navigation, especially during long flights or when flying over areas with significant magnetic variation.
