good day to you, i recently update the Navdata for XP11 and have noted that St Athan airport is no longer under the ICAO EGSY ? instead its showing under EGDX ( this hasnt been used for some years now ) there is also no airport charts or the ILS for runway 25 ?
I fly here and will happily help as much as i can to get the data if you need it.
when i input the icao into avitab its says airport not found unless i use EGDX and that gives no charts what so ever ?
i know msfs has the ICAO incorrect for this field but XP11 has pretty much been EGSY since the Airport adopted it after sheffield closed.
I can select EGSY (and not EGDX) as location in X-Plane 11. When I request a change X-Plane 11 suggests I am at EGDX. So it seems an X-Plane scenery issue.
I would report this via the X-Plane Scenery Gateway. I did see addon sceneries there EGSY (one referred to both EGSY and EGSK) , but one might be a solution for you.
I do see Avitab has an issue with EGSY, maybe because of X-Plane 11 . I suggest you raise that in their forum.
