P2:

I don't know about anyone else but the Bailey rant is getting a bit repetitive, let's just hope his Jiminy Cricket 'Mick' comes out to play, his commentary is much more informative & thought provoking...

It sure is getting repetitive...turning into a tit-for-tat exchange. I think it's also worth noting that it's industry, not an individual, that confers the title of 'expert.'  

From my vantage point, 'Mick' & 'Andrew' appear to have a professional grasp of the issues surrounding the disappearance of MH370, & subsequent search for the aircraft.

BB:

The results led me to totally disagree with the flight path assumed by the ATSB’s modelling, which used only an engineering simulator.

To suggest that a manufacturer's engineering flight simulator is somehow inferior, is mistaken. Validation data generated by engineering flight simulators is used to prove that flight training simulator performance corresponds to that of the aircraft.  

Andrew:

What he fails to mention is that the aircraft manufacturer’s engineering simulator is actually far more capable than full flight simulators used for pilot training.

Andrew is correct. Manufacturer's engineering flight simulators are heavily used throughout aircraft development. They are primarily used to verify that flight deck design is fully optimized. This includes the 'human-machine' interface. Engineering flight simulators are also utilized for testing & verifying new software & software updates that run on-board systems.

It's also worth noting that the Boeing Commercial Airplane team brings significant expertise to the table. The combined product knowledge & experience of aircraft performance engineering, Flight Operations Safety pilots, Flight Training pilots, and Fight Test pilots is second to none.

At the end of the day, I try to remember: it's better to admit you don't know something, ask a question, and learn something new than it is to pretend you know everything and remain ignorant.
