Is it possible to please update the parking codes on the AFCAD in regards to Terminal 2? At the moment, the parking codes are all AALX.
There's no Terminal 2 at KDFW, since terminals are named A, B, C, D and E. If you meant Terminal B, according to the DFW website:
https://www.dfwairport.com/guide/Terminal B is used by American Eagle, and this is why all parking spots are flagged with AALX in the scenery, and Terminal A is used by American Airline, and of course all the parking spots there are flagged with AAL in the scenery.
At the moment, Terminal 2 is dead!
It's not supposed to be dead but, instead, full of American Eagle airplanes. Provided, of course, your AI product DOES have American Eagle models and they are properly flagged with AALX themselves in their atc_parking_codes parameters.
