Interesting discussion re. the value of sim and "just a game" etc. My background is as a Grade 1 flight instructor, bush pilot, survey pilot and airline pilot. 30+ years experience and literally hundreds of Level D simulator check flights both as instructor and in the "hot-seat" left and right, operating deHavillands, Boeings and Airbus. Level D has always been considered by regulatory authorities as being of equal or better value than the "real" thing, so there's really not much to discuss there. Very first landing i did in a "real" 737, 777 and A330 was with a planeload of passengers and this is now entirely common for the industry, as we have suspended completely with "base-training" in a real aircraft, where we used to "drill holes in the sky" with an empty airplane.
As for the value of "home-sim'ing it is more complicated. From the early days, simming on a home computer held a value, but only in certain aspects of learning to fly. For IFR procedures, NDB-approaches, ILS's and holds it was great, because you could build an understanding of concepts and developing your instrument scan. For basic flight training, be it fixed wing or rotary it only held very limited value, as the inability to look around, building a "bigger" picture and developing situational awareness just wasn't there. Aircraft performance modelling was rudimentary and while I have always dabbled in home-simming, it was very much on 'n off. Enter Virtual Reality and voila - it's a massive game-changer! With VR, I have become completely proficient in flying a helicopter, through trial and error, and I can confidently state that I would be able to perform basic flight maneuvers in a variety of helicopters, including hovering in confined spaces, vertical referencing and auto-rotations etc. in a "real" helicopter. I still have ZERO flight time in rotary wing and I shall be the first to recognise the value of a good instructor, but the thing is - that with unrestricted access to a decent home set-up, it is entirely possible to get proficient in basic handling. I am not at all suggesting that I am "SAFE" to take a chopper up by myself without dual instructions from a qualified rotary wing instructor, but my hand-eye-foot coordination is well and truly sorted and i certainly would save money on rental and should be at standard with minimum time, if I go ahead and get a rotary wing conversion on my license. With the frame-rates available in Aerofly FS2 and the fidelity of the R22, using VR and small cheap motion platforms, there has been a complete paradigm shift, and I'm convinced that the training industry and eventually the regulators will catch onto this. It's most certainly not "just a game" anymore (even though it's a heck of a lot of fun!!!)
