Changing Aircraft indentification?

Is this what you want.How to Change Tail Number in Microsoft Flight SimulatorChanging your tail number is done in the exact same method. Simply go to the World Map screen and then click on the ‘Aircraft Selection’ option. Go to ‘ATC Options’ and choose the ‘Tail Number’ option.Not only can you change the tail number itself, but you can also toggle the option to show the tail number on the aircraft or not whenever you want from this settings menu.
