A ship's true course is determined by the direction from the ship to the geographic north pole (also called true north). Navigation charts andthe compass are labeled with true north, but setting a ship's course is not merely a matter of steering in relation to the north pole.
True course: the course corrected for compass errors and plotted in the chart, tc and is equal to Course Over Ground (COG) or Course Made Good (CMG) . 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.
obviousYou say of course to suggest that something is normal, obvious, or well-known, and should therefore not surprise the person you are talking to. [spoken]

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.Jan 9, 2020
GPS naturally works in True coordinates. But to provide 'backward compatibility' it also calculates Magnetic track. To do that, the avionics must maintain a current database of magnetic variation across the globe. Furthermore, remember that GPS cannot really measure the heading, it can only measure the track.Jul 12, 2019
You use of course as a polite way of giving permission. "Can I just say something about the game on Saturday?"—"Yes, of course you can." You use of course in order to emphasize a statement that you are making, especially when you are agreeing or disagreeing with someone.

The difference between the two depends on wind. A true heading or course is corrected for magnetic variation; a magnetic heading or course is not. Track and course are often used interchangeably, but technically a "course" refers to what you intend to do while a "track" refers to what you actually do.Jan 17, 2019
DrPappy Pre-takeoff checklist Sounds like Foreflight is giving you the actual magnetic course and the Sectional(and IFR chart) is giving what you would set on the OBS to fly from that VOR. The current magnetic declination in that area is 4 degrees East. The VOR is set at 8 degrees East.Jan 15, 2015
Airport runways are perhaps the most visible example of a navigation aid updated to match shifts in Earth's magnetic field. By FAA rules, runways are numbered according to the points on a compass, from 1–36, reflecting the magnetic compass reading to the nearest 10 degrees and dropping the last digit.Nov 20, 2017
