Thanks. My experience is Aviation Week is a much more reliable source on technical topics.
It's a hard switch for good reason. I hate "soft" switches that supposedly disable microphones. Phooey on that.
BTW, on my hotrod I installed a hard switch to shut off the fuel pump, as well as an oil pressure switch that would shut it off. I have a g-switch to cut it off, too, but haven't gotten around to installing it.
There it is! Knew it was in SeattleTimes somewhere!
And lookout for the part about disabling cutoff switches, I think Dominic might have written that better, because I think he's talking about a safety function that was removed specifically for the MAX where hauling back hard on the yoke would stop trim commands in progress on NG airframes? MCAS required that that functionality not be ported forward to the MAX.
This isn't disabling those cutouts though. Those are literally, like you said, a hard switch.
>According to a second FAA source, it was the AEG pilot, representing a typical U.S. airline captain, who failed to recover the jet.
There's the bit about the civilian test pilot.
