Off track heading correction technique
Many thanks for the replies.
I should have made the title of the question as above.
Currently for nav I use 10 degree fan lines and quarter etc. fixed waypoints along my route. If a correction os required I estimate the angle and double it to give heading correction required (if at quarter I'll be back on track at half).
I may be mistaken but I heard the inverse fraction method referred to hdg correction (I use it for revised ETAs). So at the quarter waypoint if I was 5 degrees off-track I'd apply 4x5 20 degs of hdg correction. This can't be correct as it would imply less of a correction at the 3/4 point.
Another method in a textbook confirms my thoughts as it applies factors of 1.5, 2, & 3 and the 1/4,1/2, & 3/4 points respectively.
I was just wondering if anyone used it the inverse fractrion method for hdg correction, as I can't see how it will work.
