There're thousands of add-ons on the Web for the classic FSX and Prepar3D v1 to v3. Take off from anywhere in the world, flying some of the world’s most iconic aircraft to any one of 24,000 destinations.
I have this installed with my steam version of FSX, all of the 747-800 planes bounce on the tarmac/runways. The default 747's don't and the other 747 packs don't either. I'm running win 10, I-7 @3.2ghz, 16 gb ram, 1 tb hard drive, rtx 2070 8gb video card.
