Yip, fair point. I’m completely happy to be wrong on this message exchange issue. It just wouldn’t surprise me if,when we know more, it is not quite as it seems. Potentially he had told the regulator that MCAS only kicks in at the higher Mach numbers ( because he thought it did) and he was worried because he had told them something that wasn’t accurate. That doesn’t necessarily mean that the MCAS was firing up at 4000 feet level and 230 kts.......that would be truely concerning I agree.
It may be the case that I simply can’t imagine so many individuals staying silent as the plane goes through final certification so I’m scrambling for alternatives, or, that we have been presented with half a story and the full story will look different.
I’ll be interested to find out which it is.
