    Correction to oroboros' comment:

    This formula converts True Course to Compass Course. Magnetic course is the middle step (TV*M*DC)

    (T)rue course +/- magnetic(V)ariation = (M)agnetic course

    then

    (M)agnetic course +/- compass(D)eviation = (C)ompass course

    Thanks for your correction; only saw it for the first time today! As a retired USAF and airline pilot (10 years, this month) this formula is a hazy recollection from USAF pilot training a lot of years ago. I've had the luxury of black boxes for my entire career after that and have never done any small aircraft flying outside that career, so thanks, again, for your clarification.
