Hi all,
I'm just working my way through BT's Navigation Workbook.
I'm calculating my True, Magnetic and Compass Directions.
With a few of the calculations I've been out by a degree on the compass directions and I can't seem to find the hard and fast rule.

I'm pretty sure that CASA's marking system would allocate full marks for that answer. Sensible margins are applied to CASA's 'perfect' answer. It's likely that the variation between magnetic and compass direction is not perfectly linear anyway.
