Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

If indeed it is an MCAS induced crash then the primary responsibility is Ethiopian’s training. I think we can presume that 737 drives have heard about the JT accident and MCAS. But even with the JT case, there was discussion about how easy or not the fight agains the airplane is. People make it sou...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

I downloaded the data from the blog and I would say it is an MCAS case.

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

The retraction of the flaps is mainly related to the airspeed. The last data recorded by FR24 shows a ground speed in excess of 380 kts (and it was still a head wind component, since it was still flying in the same heading as it had taken off). Even considering the 8500 ft altitude, the flaps must ...
