Hi Umberto,
Sorry, I have read a similar problem on the forum and solution but can't find the thread.
I landed at Diagoras Airport in Rhodes LGRP (Greek Airports Project addon) using CLS 767 and GSX only gave me parking options for nearby Maritsa Airport LGRD (default scenery).
I removed scenery indexes to build a new one and GSX gave me correct prking options at Diagoras, but after another flight is was reading the wrong AFCAD again (using Maritsa instead of Diagoras).
How do I turn off the AFCAD for Maritsa LGRD?
Sorry, I've read a similar problem and solution on the forum but can't find it.
Thanks!
