jdToday I flew from aus to msy which i do quiet often. After I was given to approach cleared for ILS rwy10 Otto was flying. He gave the plane back over to me. Knowing that rc will not line you up with the runway I began watching my headings on rc. When 10 and KMSY was at 104 deg I set my heading to such. When it was time to line up for the localizer to take over and I was at FL18 I was watching my GPS and I ended up about 2 1/2 miles off. So this tells me that either rc was off on the heading or my panel was off. This also happened last night when I flew to KJAX. I also had to go missed. RC later did take me to a straight inbound heading whic lined up perfectly. I have to log to send if you need me too.

send it onhow were you at FL18?jd
