Ha! I think you hit the nail on the head with your first sentence. Except it should be re-written to read: "Boeing may have the ONLY simulator with MCAS functions in Seattle".

I doubt that the...

There certainly are! The first was delivered to the Boeing Miami Flight Training Center in April 2017 and multiple simulators have followed around the world.

I think that is exactly the case. This MCAS system is something added for the MAX (but not documented...). There are lots and lots of NGs out there, and I think it safe to assume both Boeing and the...

Except the cause of the trim behavior (AOA sensor invalid) in this case wasn’t understood to affect the STS, or even that this was an AOA sensor related issue. The use of AOA within the STS system is...

I can’t seem to copy paste but above the post questions why safety has apparently improved so drastically...

Seems the NG is different

“Does the MAX use AoA data in any way differently to the NG?
If the use of AoA sensor data hasn't changed from the NG then this accident must truly be a black swan event”

Based on the Boeing and...

I've tried to point out that with the MAX, all Level D FFS simulators will be using a binary supplied by Boeing that encapsulates pretty much the entire simulation - this binary is essentially the...
