IMHO, the whole issue of a further "simulation" is a complete waste of time and I believe it is simply an effort by the MoD/Govt to muddy the waters. Basically, we must be aware of the limitations of what they are attempting to do. It is the MoD trying to appear “rigorous” in its’ assessment of the case when it simply does not have the DATA to support such an assessment. In scientific terms, the whole thing is based on “fairy tales”, with so called Data being based on what people thought may be happening at the time; possibly that altitude, possibly that airspeed, possibly that Nr, possibly that AoB, possibly that AUW, possibly that OAT, …... Really, need I go on?. .. .It matters not one iota what software standard the FADEC is, or anything else, for that matter is in the simulation. The simple fact is, that to drive a simulator to accurately reconstruct events, you need algorithms which accurately represent the aircraft characteristics and then the accurate DATA to feed into those algorithms so the simulator can respond accordingly. We must give Boeing/MoD the benefit of the doubt as to the validity of the algorithms used. However, we all know that the aircraft was not fitted with a FDR or a CVR. So where is all this supposed Data coming from? Yep, “Common you Fairies!”, lets dream up some numbers to plug in. Now, just how scientific is that? It will be down to Boeing/MoD doing what they THINK happened on the day. The truth, as we all know, is no-one apart from the deceased (RIP) actually know what happened. Indeed, I believe that, towards the end, even they did not know what was actually happening. If they had, aside from a mega-deathwish theory, they would not have flown into the side of the Mull.. .. .So what can the so-called “simulation” achieve? At best, all they can do is to fly likely profiles under likely conditions and thrown in some possible malfunctions. A tad un-scientific if you ask me! Remember a year or so ago when “Horizon” (I believe) on UK TV went through some civil air crashes? There, actual data from the FDR was fed into the simulator, second by second, in real time, along with the CVR audio. Eerily, Boeing were able to “drive” their simulator using this real-time Data, recorded by the FDR, to drive the aircraft round the virtual sky exactly as the actual aircraft had done on the run-up to the crashes - right up to the moment the FDR stopped recording. I think what the MoD is hoping to do is convince us all that they have recreated the actual flight profile in the same way - but they can’t. Quite simply, they do not have the data to do it. No-one has – unless you believe in Fairies that is.. .. .Now, knowing the MoD and Government, that last point is probably not too far off the mark! <img border="0" title="" alt="[Razz]" src="tongue.gif" />
