Mag Course mismatches
How many direct magnetic courses can there be between two points? Sometimes the answer is three. How many can possibly be right? Actually, all of them.
I looked at the arrivals into Chicago O’Hare and noticed something peculiar. Both the BENKY ONE and BRADFORD FIVE arrivals have a transition route from Kirksville VOR (IRK) to LOAMY intersection. But the BENKY arrival shows a course of 068 degrees while the BRADFORD arrival shows 059. I put IRK direct to LOAMY in my GPS ... and got a third course of 064.
