What is the difference between true and magnetic?
What’s up with Magnetic North vs True North? “ True north” is the northern axis of rotation of the Earth. It is the point where the lines of longitude converge on maps. “ Magnetic north” is the point on the Earth’s surface where its magnetic field points directly downwards.
Do aircraft use magnetic or true north?
Most large aircraft use inertial reference units and flight management systems that complete calculations using True North and add magnetic variation values from tables to display information to pilots.
What is the difference between true course and magnetic course?
Magnetic heading is your direction relative to magnetic north, read from your magnetic compass. True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.
Do you fly magnetic heading or magnetic course?
Magnetic Course: True course corrected for magnetic variation. Magnetic Heading: True heading corrected for magnetic variation. You can determine the magnetic variation from a sectional map. True Course: The aircraft’s course over the ground relative to true north.
Are VORS true or magnetic?
VOR degrees are magnetic, not true, so you can read your magnetic course for that location right from the VOR rose. Again, the difference between the true course you’ve drawn on your chart and the magnetic course that runs through the VOR rose is the magnetic variation.
Do magnets work underwater?
Water is almost completely non-magnetic, so magnets work underwater the same as they do in air or in a vacuum. Magnets underwater work like they do above ground—if they find something they’re attracted to, the force between them pulls them together.
Does GPS use true north or magnetic north?
The GPS receiver natively reads in true north, but can elegantly calculate magnetic north based on its true position and data tables; the unit can then calculate the current location and direction of the north magnetic pole and (potentially) any local variations, if the GPS is set to use magnetic compass readings.
What is magnetic heading?
Magnetic heading is your direction relative to magnetic north, read from your magnetic compass. True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart. There are some interesting reasons why these poles are not in ...
How does a compass work?
Without getting into exactly how a compass works, it’s basically like this: The compass contains certain metals (magnets) that are attracted to metals inside Earth’s crust and thus the magnetic compass orients itself to magnetic north. To find true north, you need to know the nearby variation.
What is true north?
True North is the North Pole. The maps used for navigating are oriented to the North Pole. A pilot can measure the direction between two points to create a “track” or “course” to fly in degrees true.
What is the North Pole?
The true north pole, also known as the celestial north pole, is the point on the Earth’s surface intersecting Earth’s rotational axis on the northern hemisphere (and the axis around which all stars appear to rotate).
What is true heading?
True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.

How is course similar to bearing?
Course. Course is very similar to bearing in that it’s the desired direction for your route of flight. If you are going directly from one airport to the other, your course and bearing will be the same along the route of flight. If you are flying from an airport to a VOR to another airport, your course will change in each leg, as will your bearing.
What is heading in airplanes?
This does not factor for wind, or the actual movement of the airplane across the ground. It only refers to what the compass reads based on where the nose is pointed.
What is the difference between a track and a heading?
Heading is the direction the airplane is pointed, whereas track is the actual direction of the airplane tracking across the ground. Bearing is the angle between any two points, whereas course is your intended path of travel to your destination. In the rest of this post we’ll elaborate on each of these points and then also provide ...
Why is bearing confusing?
Bearing can be confusing sometimes because has some overlap with course. Bearing is simply the angle or direction between two points. A practical application of this is in VOR navigation. It’s a common thing to hear someone say “we are bearing 090 from the station”.
What’s The Difference Betweentrue and Magnetic North?
Thesimple reason that we use both true and magnetic headings, is because we have two Norths: true north and magneticnorth. According to chapter eight of the Pilots Handbook of Aeronautical Knowledge (PHAK), “The Earth rotates about its geographic axis; maps and charts are drawn using meridians of longitude that pa…

Why The Difference Between trueand Magnetic Heading Matters
- In the grand scheme of the size of Earth, one can see that true north and magnetic north are relatively close. This is especially true from the perspective of those of us in the New World, but if you were sailing off the west coast of the British Isles, you might see up to a ten-degree difference between your compass and Polaris, and that’s significant over a distance of even a few hundred …
Magnetic North Has Moved Overtime
- Earth’s magnetic pole changes over time. According to surveys dating back to the past 130 years, magnetic north is moving closer and closer to true north. One PHAK explanation said this could be due “possibly to gyroscopic stabilizations of the convective flows within earth’s liquid inner layers. Again, for most of the U.S. the practical effects of observed shifts are minimal, but it has …
Why We Forget The Difference Intrue and Magnetic Headings
- Intoday’s world it’s becoming easier and easier to simply input an airport intoour GPS, and push “direct, enter, enter”without much thought. The worst part (for CFI’s teaching new private students)is it’s highly accurate. GPS units have the magnetic variationincluded in their database and, knowing its position, will apply theappropriate value to the true track it has calculated. AGP…
Conclusion
- Truenorth and magnetic north are two things that aren’t thought about with everydayflying, but they are the groundwork, the soil, the algorithm of the common GPSwhich helps us get from point A to point B most directly. Flyingin today’s world requires a tight-rope walk. A good pilot today should not onlyknow the intricacies of GPS or “glass panel” flying, but should also have theneces…
