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've looked all around and I've YET to find a DECENT freeware panel or virtual cockpit that I can put in the 748F that I fly (i'll have to dig for the link later lol).
the one I have uses the default 747 panel which hey whatever, it works...but I would actually like to find a decent VC. GRANTED, I normally fly in the 2d panel but eh VC is nice now and then for when you got a nice sunrise or sunset ahead of you
