How to change your TAIL REGISTRATION and CALLSIGN

I may have found something for this.

look for this folder
E:\MSFS2020\Official\OneStore\[aircraft you want to fly]\SimObjects\Airplanes\[whatever plane]\ (May be different on Steam, I have GamePass version)

Mine for the 152 is: E:\MSFS2020\Official\OneStore\asobo-aircraft-c152\SimObjects\Airplanes\Asobo_C152

Open file aircraft.cfg

Look for line

atc_id = "ASXGS" ; tail number

near the bottom

Change the ASXGS to whatever you want.

Save.

Reload plane (?)(or sim?)

Make a backup of this file or folder just in case. I won’t be responsible for you having to reinstall 91GB :wink:

That might keep it from changing back.
