Boeing to warn 737 MAX operators of a potential instrument failure that could cause the jet to nose-dive
Last week's Lion Air crash in Indonesia has prompted Boeing to issue a safety warning to all airlines operating the 737 MAX, instructing pilots in what to do if a specific sensor failure arises. (www.seattletimes.com) Mais...

As I am seeing pilot training develop you see people who simply take off and land and leave cruise to button pushing. And most airlines have rules AGAINST hand flying until the very end or beginning of a flight.
You need to understand what you are seeing and act on it. Once you know. It’s triage. A sudden uncommanded descent means act now. Thinking is not called for. Which means be a good aviator not a pilot.
If the pilots did not have their belts fastened the uncommanded descent pulls them out of their seats knocking them unconscious which is fatal for everyone. Given the nonchalant attitude I see in aviation everywhere these days . . . Those five point harnesses are uncomfortable for a 10 hour day.
Look. No one knows anything yet. But those airplanes can and do phone home. The maintenance of the aircraft was known by Boeing.

You know. You were there.
Perhaps the rush to market mentality very prevalent in the auto industry, with only 2 a/c manufacturers trying to vie for the most booked orders, Boeing has a design deficiency. Add to that, the demand for qualified pilots of which may be an issue as well... then there are the pitot tubes which may be sadly overlooked on the pre-flight inspection. One has to wonder about the possibilities of any of these hiccups, but, the fact remains, 189 people perished.
Boeing pushed Max as a very passive and rushed response to the successful A320neo...
Lion Air suddenly booked because budget air travel in and around south east Asia is underdeveloped and they want swiftly to have a large market share...
And we all know, when you rush something...

From Boeing: The AOA is used to drive stall warning, stick shaker, stall margin info on airspeed indicators, pitch limit indicator.
It comes from this: (this file wont take photos). Anyway, an AOA Vane on the side of the A/C, just behind that is a transducer which changes analog movement to a to an electrical signal. That signal is fed to both Air Data Computers which drives all the above.
Failure of this unit (transducer) would create extremely dangerous conditions; stick shaker, stall horn (very loud), erratic airspeed, climb and dive, etc. Daytime VFR would be demanding (probably the source of the previous write-ups). Night IMC would most likely be fatal.
That A/C required a maintenance check flight.

If the automation clauses Uncommanded actions it needs to be marked inop until the cause is found. Do not throw parts at it. And why didn’t the pilots simply turn off the system?
Automation is literally going to be the death of us all.
