    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,
