Re: Boeing 737MAX Grounded Worldwide Q3 2019

Hence why SteinarN referred to it as elevator "worth". In other words, MCAS put in enough stabilizer trim that a pilot would need to put in 71% elevator travel to counteract. I think. (I'm not a pilot thank God) Exactly. But my numbers is some pure guesswork, some is more educated values ...

Re: Boeing 737MAX Grounded Worldwide Q3 2019

So, we see, with these numbers, that we put in a positive 25.6 percent elevator travel going from 10 degrees to 14 degrees AOA, but at the same time MCAS puts in AND negative 71 percent worth of elevator travel MCAS works through the trimmable horizontal stabilizer, not the elevators. Hence why Ste...

Re: Boeing 737MAX Grounded Worldwide Q3 2019

I have tried to make some thought experiments. We know MCAS at low speed was supposed to administer up to 2.5 units AND trim. We dont know from which value of AOA that AND trim was supposed to be started. We know stall begins at approximately 14 degrees AOA and is well developed at 15 degrees AOA. W...
