ATC_ID field wrong in aircraft.cfg

[Muad'dib]

Hello,

As I use fleet package with BATC injector there have been found an issue by BATC developer team about the ATC_ID in some of the fleet package aircraft.cfg files.

It should have the register of the according livery/model but instead there are random things
like "737 or A32X" which makes the BATC injector not working properly.

Please check and fix in the next update.
