cc + var + dev = tc: this equation shows the connection between the compass course, its errors and the true course. It can also be read as: tc − var = cc + dev.
True Course is the direction of travel of the vessel. Also, is the dihedral angle formed between the True Meridian Plane and the Longitudinal Centre Plane of the vessel. True Bearing is direction to object.
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.
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.
How to Find Variation with a Compass RoseFind the difference in years between 2012 and 1985. 2012 - 1985 = 27 (years).Multiply 27 (years) X 8' (decrease per year) = 216' or 3º 36'.Apply this to the variation shown. ... Round off the final number to the closest whole degree.

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 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.
