Hi Umberto,
I'm sorry for replying in a thread inactive for more than a year, but I thought it would be simpler this way.
I bought GSX on February 4 and I'd like to inform that I am having the "catering vehicles are on their way" stuck message issue with the latest Aerosoft Airbus (tested with A319 and A320) on default and 3rd party airports. It does NOT happen when all service doors are active, in which case both trucks appear, do their job and the service completes. But I chose to remove the front service door, for I believe that would be more realistic for the type of operations I usually simulate. That's when the mini van appears and the issue occurs.
The workaround solution of setting the height of the door to 10m worked for me, but I thought it could be helpful to inform that apparently this is not an exclusive Dash 8 issue.
Congratulations on a great product!
Regards,
Bruno.
