Plus one other.....
Boeing procedure stated in the manual, they claimed they didn’t have to document separately for MCAS failure because it’s treated identically as a subset of Trim Stab failure.
But, Ops procedure should be tested in the simulator, like everything. And news just in, is that if Boeing had done so, the software is now known to hang!
And Boeing didn’t originally test the fix they just spun because there are only two Max simulators in the US.
So we have just effectively discovered Boeing *definitely* haven’t actually tested *any* of the manuals emergency procedures on the Max simulator!
Never mind MCAS, this planes operating procedure is essentially untested. All of it.
I thought it couldn’t get worse for Boeing, but this is!
