Does anyone know if current FSX addon aircraft can be ported to the new sim?

I haven't tried yet. The reason is that at the moment, the only aircraft available to fly in FSW, are single  engined, and twin engined, propeller aircraft, and I don't know what would happen if I tried adding a multi-engined jet from Captain Sim.

Hopefully, as FSW is updated, more aircraft, including jet airliners will become available, and then I will try adding a Captain Sim airliner (probably the 727, or 737).

Edited [timestamp=1496119357]: The folder structure of FSW is the same as FSX, so it might be easier than I originally thought to add a Captain Sim aircraft! I will try it once I get Windows 10 up to speed (I had to reinstall it last night after it messed up my compter, and denied me access to Windows 7). :(
