Go into the aircraft.cfg file and and find the line "atc_id=" for the aircraft whose tail number you wish to edit. Simply type in the tail number you wish to use. So the line would look something like this, atc_id=N1234AB.
When you load up FSX, select the aircraft and click Details. Check to make sure the tail number you chose is listed for the aircraft.
