You'd have to laugh if it wasn't so serious.
But that's what these tests are for.
And who did the sim tests? Was it the FAA or was it Boeing? If it was Boeing you'd think that this would have been kept internal and just quietly fixed as part of the software testing?
SparkyFX:
This mentions government pilots.
Microprocessor... could be anything.
floobydust:
If the flight control computer crashed, it might be an older CPU out of RAM... due to new features. Fault tolerant, redundant processor systems take years to engineer and test and we all know the 737 max. is a rush job.
When Muilenburg announced the MCAS fix is using three timers i.e. triple-redundant S/W I had to cringe because this is so stupid.
Boeing couldn't even deal with two sensors, let alone three timers. It's a noob fix, those have psychological value but no real value adding safety.
I'm sure there's an AoA sensor failure that can cut in and out at a rate that new MCAS will screw up on.
I can't see the planes being up in the air this year.
BBBbbb:
I do hope BA got a hell of a discount on the recent order of 200pcs of these things...
