I created a flightplan using TTools for an aircraft to leave Las Palmas (GCLP) to Manchester (EGCC), TTools accepted it and compiled it no problem.
I go to view the aircraft a GCLP and that airport isn't there in the drop down list, I go to Manchester a little before the arrival and sure enough I pick up the aircraft on approach, in TrafficToolBox it said it was from GCLP which is correct, so if TTools and TrafficToolBox accept it where is the airport in the sim?

I re-installed the scenery from Disk4 but still no GCLP is listed, in case you ask I don't have it as an addon scenery either so it isn't there, any ideas please, it might be something staring me in the face?

OK A simple question. Do you have all the regions installed in your sim?
The reason I say this is because it is in mine and it resides in the Africa region.

Steve you are a genius, that was it mate, thank you. I don't know how it de-activated may be something I did ages ago and forgot, any way it's there now, also I was thinking it came under Europe.

No problem. All you need now will be an afcad so you can see your AI traffic.
