Another question could be, Is it easier or more difficult? Meaning that if some systems, ordinance lethality, ordinance accuracy and others have been toned to be less effective or simply there are some systems that are missing (which probably make things easier for the pilot) then this :
Matt Wagner: After working on the software A-10C for a couple of years I had the opportunity to sit in the USAF full dome A-10C cockpit simulator. Based on our software, I was able to start up the aircraft, taxi, take off, navigate, kill the target, and land without a problem. I see no reason why one of our DCS: A-10C Warthog customers could not do the same.
Not only is probably very true but maybe also some situatuions are also easier to handle for a RL A10C pilot. Off course we have to keep in account that DCS world Manpads, Infantry etc.. dont move, run away or hide, apparty from weather, winds etc.. etc..
