AVIATION & AERONAUTIC CALCULATOR
True Heading
A precise tool.
What is the True Heading & How does it work?
The true heading of an aircraft is the direction in which it is pointing relative to true north. This is different from the magnetic heading, which is based on magnetic north.
To calculate the true heading from the magnetic heading and the magnetic declination, you can use the following formula:
text{True Heading} = text{Magnetic Heading} + text{Declination}
TH = True Heading, MH = Magnetic Heading, D = Declination

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 based on magnetic north.
How do I calculate true heading from magnetic heading?
Add the magnetic declination to the magnetic heading to get the true heading.
Why is it important to know the true heading of an aircraft?
Knowing the true heading ensures accurate navigation and helps avoid errors caused by magnetic variation.
Can you explain what magnetic declination is?
Magnetic declination is the angle between true north and magnetic north at a specific location.
How often should I update my magnetic declination value?
It’s recommended to use the most current declination values, which can change over time due to geomagnetic shifts.
What happens if I don’t account for magnetic declination in navigation?
Failing to account for magnetic declination can lead to navigational errors and off-course flying.
Can this calculator be used for any type of aircraft?
Yes, this calculator is applicable to all types of aircraft that rely on heading information for navigation.
