Compass Error 3 - Calculations
Let’s find the compass course to steer from a true course.
Our true course plotted on the chart is 050°T.
Variation is 10°W.
From true to magnetic add west.
050 + 10 = 060°M.
Deviation is 5°W.
From true to magnetic add west.
060 + 5 = 065°C.
Our course to steer on our compass is 065°C.
Make sure you write the ‘C’ so that we can tell it’s a compass course.
