I noticed that a lot of airports in the X-Plane DB are quite far out.
Even some major airports like Sion were out by ~ 3 km.

What I do find interesting is that the quality of the data seems to change for 
every country.
South Eastern France's data was horrid, so was Switzerland's however Italy's 
data was almost spot on more than 90% of the time.
Maybe someone corrected the data for Italy already or maybe it came from a 
different source.

Also it appears that a lot of the data was pure guess work in a lot of cases.
I saw plenty of runways that were more than 20 degrees out, runways that were 
more than 50% too short, wrong runway id's, wrong surface types, etc.
Ever seen a military airport with a single 500m long grass runway that they 
use for F18's, Mirages, etc?   :)
