So, anyway to make ATC call you as a Airline?

It seems to be a bit hit a miss with the planes i've downloaded, i.e that some come with the callsign included in the package and some don't, in which case ATC just identify you with a number.

Have a look at this ➡

Liono

open the aircraft.cfg using notepad
change the atc_airline=Landmark
from landmark to whatever you airline you want.
If it doesn't recognise the airline then it will spell the airline name out letter by letter. ie
atc_airline=Speed Bird
will be correct for British airways and the contoller will sa SpeedBird
but if you put in
atc_airline=Speedbird
the the ATC will say sierra, papa,echo,echo,delta,bravo,india,romeo,delta
