Somewhere, sometime, somehow I entered a call sign for my various aircrafts and FSX ATC almost always identifies me as this set of letters & numbers, but for life of me I can't find where I entered this. I posted this question previously and was advised I can change this in each plane's detail dialogue, but when I select an aircraft and click their details the call sign that is being used IS NOT the one that's in the details dialogue! And what's really odd, on occasion ATC will use a different call sign, like UNITED 842 Heavy, and the next time in the same plane it will be my default string of "NCP459" or what have you. Help!Thanks in advance,Noel

You can change the callsign in the aircraft.cfg.

Have, you checked the flight numbers in the aircraft config file "atc_airline=southwest, atc_flight_number=316" are the lines I am refering too.

HI Noel; Open the aircraft.cfg: look for the [fltsim.xx] that you want to change: For GA aircraft - go down the parameters 'till you come to "atc_id=". There will the the alpha-numeric call sign in that spot, i.e. "atc_id=P8342" (no quote marks). You can change this to simply "8342" or "342" if you wish. For airline aircraft - as John says - if you put something in the "atc_flight_number=xxx" - it will use this number in its place, and the same with the "atc_airline=xxxx"The second piece you may need is in the [General] section; namely "atc_type=some name".This is where we can get rid of "Experimental" and replace it with "Supermarine", as I, like many flyers don't like my Spit to call me "Experimental"! So, having made those changes, when I fly the Spit - atc calls me "Supermarine 832" - just what I want! OK?( Hi John! Like the avatar? )

Great, I'll look there. Thank you kindly!I must say though, I do not recall ever going into these individually and changing them to my 'default' entry. Noel
