NavList:

Andres,

I would avoid using CC. This is used to indicate compass compensation or degaussing compensation. MT would be very confusing so drop that.

As per Bowditch when swinging the compass:

TC True Course
V Variation
MC Magnetic Course
D Deviation
CE Compass Error
CH Compass Heading
MH Magnetic Heading
TH True Heading
GE Gyro Error
Hpgc Heading per gyro compass

Chart plotting will be different to avoid clutter. It is understood that C = true course and S = speed in knots on a plot.

Thanks Greg,

for the variables used, please see screenshot: Magnetic compass
is it correct to use TC for true course, MT for magnetic, and CC for compass course?
and other variables.

best regards,
