Who does the maths?
Course Reversal Add 2 subtract 2 or subtract 2 add 2 for course reversal. Ex: If you are on a heading of 060 you +2 & -2 = 240 Ex: If you are on a heading of 340 you -2 & +2 = 160 A little common sense and it always works.
I found this on a link from this forum and I just cant make any sense of it at all any ideas ?
