Sorry, if this has been asked before, but as I still have to read about 1000 pages of the manuals, I thought it would be quicker to get an answer here. As I understand the MD-11 was delivered with three engine variants: Pratt & Whitney PW4460 (266.9kN / 60,000lb), PW4462 (276kN / 62,000lb) and General Electric CF6-80C2D1F (273.6kN / 61,500lb). So, if I want to use the most powerful engines, which liveries do I have to use. Of course it is easy to discard all GE - powered aircraft/liveries BUT which airlines used the PW4462 engines?Richard

O.K....in the meantime I found out myself: as there is only ONE airfile in the PMDG-folder, the different engine-versions are all the same anyway!
