scbriml - Where are the crashes over here ? The shear number of flight hours should suggest at least 4 crashes / crash landings etc . But there are none so please explain . Our opionion is the 737 max should have been grounded where the 2 airlines were not all over the world. You said - Do you and your friends know how many times US MAX pilots have faced the same issues that Lion and Ethiopian faced? the difference is they are still walking and talking . In our opionion those 2 flights were 70 percent pilot error , 20 percent airline maintenance error aand 10 percent aircraft. What worlds aviation aurthorities ? Everyone on the 2 investigation boards worked for government agencies here and over there.
Well you still have not explained the huge i mean huge difference in flight hours with no crashes to the 2 over there. Those 2 airlines combined did not have even one third the flight hours on the 737 max that others have with no crashes.
I'll try and explain the huge difference in flight hours if it will help. The Air safety databases say the MAX fleet made c. 650 000 flights worldwide before the grounding. http://www.airsafe.com/events/models/rate_mod.htm
You think that 40 000 of those flights were in the USA - i.e. about 6% of flights.
Ertro posted where the delivered MAX's have gone - c. 16% of the delivered fleet going to US airlines
Either way, the HUGE difference in flight hours you refer to is biased the other way, i.e. outside the USA.
Can you point to a US case where the AOA sensor has failed as it did on the Lionair and Ethiopian flights?
It is entirely plausible that no such failure had occurred in the USA up to that point, so no US pilot has been exposed to it.
It is equally inevitable that at some point it would occur in the USA, given the failure rate stats for an AOA sensor.
And given that the STUPID
architecture was not only dependent upon that single sensor, but was also INSANELY
designed to ACTIVATE
when the sensor failed - AGAIN AND AGAIN AND AGAIN
...it is entirely plausible that the outcome might have been exactly the same - US pilot or no US pilot.
That one bolded sentence above is why a lot of posters who are bigger fans of Boeing than I am are frustrated by what they have done.
No sane engineer alive today would consider that a rational solution for a safety system.
I might suggest that you and your friends might want to work your way past the defensive jingoism and take an objective look at the statistics, and the circumstances, before adopting the role of representatives of the "injured" party.
If it helps massage that nationalism somewhat, the thing that makes this really hurt is the world class safety record of every other Boeing model flying today - in the hands of the same pilots and maintenance teams, it has to be said.
Boeing DO know how to do this.
They just failed in this instance - with catastrophic consequences.
