None .... because I prefer to make my own aircraft list and my own flight plans for general aviation and military. I once "edited" the downloaded flight plans from TT, but that was a fools errand because there are so many, so now i have TT's flight plans for the big boys but with my downloaded passenger jets...not default. papa-metro usaf 1953-57
you can count anyone which is complete (all flightplans and aircrafts installed)! my skies are getting so busy, really cool....the only disadvantage is the massive drop in FPS when approaching even a middle-sized airport...and yes, I prefer to stay away from places like heathrow!
