Or Boeing has the ONLY simulator with MCAS functions in Seattle?
The investigation will next head to Seattle and the 737-MAX engineering simulator where investigators will attempt to exercises to better understand what happened.
If Boeing didn't think it was important enough to mention MCAS in the QRH, why would they provide the code for it in a multi-million dollar simulator? Textron/TRU has 737 MAX Simulators in Miami as of 4/2017, but I would be shocked if they could replicate this flight. I don't think you get extra play time @ > $1,000/hour?
