I've been doing VOR and ILS approaches for some time and come across errors which make it harder to fly these approaches. 

 

-1. Discrepancies between the VOR course and heading required to stay on course.  For example take the VOR B approach at KPAE - to keep on the 160 degree course inbound to the runway a heading of 160 degrees would be required in zero wind conditions, but this does not work.  It turns out only a heading of 163 degrees keeps the needle centered.  This may not seem like a lot but it does add to the workload and is annoying!

-2 Discrepancies between FSX's ILS final approach heading to fly (that you see when you hover the mouse over the ILS feather on the map) and heading required to stay on course, again in zero wind conditions.  For example take the ILS or LOC RWY 16R approach at KPAE.  FSX says a final approach heading of 159 degrees is required , but to keep the localiser needle centered requires a heading of 162 degrees!

 

Help really appreciated

 

Thanks.

That's all normal

Other than checking to make sure you are not flying a heading of ~340 degrees, forget the heading and center the needles.
