How to determine magnetic variation in aviation?
You can determine the magnetic variation from a sectional map. True Course: The aircraft’s course over the ground relative to true north. True course is measured with a navigation plotter and a sectional map. True Heading: True course corrected for wind. You might be interested: FAQ: What Is Ifr In Aviation?

What is true course in aviation?
True Course: The aircraft’s course over the ground relative to true north. True course is measured with a navigation plotter and a sectional map. True Heading: True course corrected for wind. You might be interested: FAQ: What Is Ifr In Aviation? Do aircraft use magnetic or true north?
How do you fly a magnetic course of 180 degrees?
If a pilot wants to fly a true course of south (180°), the variation must be added to this, resulting in a magnetic course of 190° to fly. Flying in the Los Angeles, California area, the variation is 14° east. To fly a true course of 180° there, the pilot would have to subtract the variation and fly a magnetic course of 166°.
Is cross-country flying impacted by True vs magnetic headings?
Additionally, it’s not only cross-country flying that is impacted by true vs. magnetic headings, but the winds themselves can be reported in true and magnetic headings depending on where and how they are reported. See our article on “Are Winds Reported in True or Magnetic Headings?”
What is the difference between true course and 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.

The magnets are mounted to a float.
What is magnetic heading in aviation?
What is Magnetic Heading in Aviation? Magnetic heading is the direction the aircraft is pointing, given by reference to a magnetic compass. The magnetic compass will always be aligned with the north magnetic pole. It is important to note that it is not the same as the geographic North pole!

So your true course is 40 degrees.
What is the difference between compass course and magnetic course?
Compass course: (cc or CTS) the course which is corrected for both variation and deviation. Magnetic course: (mc) the course which is only corrected for variation. cc + var + dev = tc: this equation shows the connection between the compass course, its errors and the true course.
What is magnetic course in navigation?
Definition of magnetic course : the course on which an airplane is intended to be flown that is measured from magnetic north and that is the true course as laid out on the chart.
Are runways true or magnetic?
No. All runways are numbered based on the magnetic azimuth (compass bearing) in which a runway is oriented. There are 360 degrees on a compass rose.
Do pilots use magnetic or true north?
Pilots navigate using magnetic headings, but directions on a sectional chart are in reference to true north. The angle between true and magnetic north is called variation. Understanding the difference between true and magnetic headings is important for flight planning.
Is VOR magnetic or true?
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.
What is the difference between heading and course?
In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered. The course is to be distinguished from the heading, which is the compass direction in which the craft's bow or nose is pointed.
What is compass course?
Definition of compass course : the course with respect to true north in which a ship or an aircraft is intended to travel.
Are runways magnetic or true?
No. All runways are numbered based on the magnetic azimuth (compass bearing) in which a runway is oriented. There are 360 degrees on a compass rose.
Do pilots use magnetic or true north?
Pilots navigate using magnetic headings, but directions on a sectional chart are in reference to true north. The angle between true and magnetic north is called variation. Understanding the difference between true and magnetic headings is important for flight planning.
How does the magnetic compass work aviation?
Vertical card compasses use eddy current damping, essentially a magnet energized through a small conductor that creates an opposing force. The magnetic compass has been used in navigation for more than 1,000 years, and in aviation since at least 1909.
Does aviation use true or magnetic north?
Aviation sectional charts use true north for their orientation. The second north—magnetic north—is the location of the molten core of the Earth, which is constantly (and quite rapidly) moving.
