Hi Bertrand,
thanks for your examples and your error report. All these example are offset approaches, that means that the localizer antenna is not aligned with the center line.
When you look on the charts, you see this - look for “OFFSET LOC” and the offset under the ILS frequency.
Here LIRN 06 from your example:
Here also a question about LIRN 06 and the offset, directly here from the forum:
Hope that explains now, the offsets for you. It’s in all your examples the same reason. You use real world data in XP and MSFS … so, its no data issue.
Thank you
Richard
