Derived Data - SetDrift - Drift Calculation, Magnetic vs true
I have pulled this out of a discussion in the KIP area but:
looks like the Drift calc uses 'Math.cos(courseOverGroundTrue - headingMagnetic)' to get the angle, shouldn't they both be True, like 'Math.cos(courseOverGroundTrue - (headingMagnetic + magneticVariation))'?
