This diagram is your navigation cheat sheet!
It shows the transformation between:
True (based on the geographic North Pole)
Magnetic (based on the Earth’s magnetic field)
Compass (influenced by aircraft systems)
Use these conversion layers:
TC → MC → CC (Course)
TH → MH → CH (Heading)
TT → MT → CT (Track)And don’t forget the angles:
VAR = Magnetic Variation
DEV = Compass Deviation
WCA = Wind Correction Angle
DA = Drift Angle
Mastering this concept is vital for precise navigation and ATPL success
