Re: Boeing 737MAX Grounded Worldwide Q2 2019

The 9 seconds because the stabilizer can only move so fast. It took 9 seconds to move the amount that was determined was needed under a worst case scenario (I'm guessing low speed where the stab has less authority). The pilots aren't normally intended to turn it off. I understand the 9 seconds. But...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

I'm seeing all this Sully stuff floating around everywhere now. I realize he has a long history as a pilot with time in the military, 30 years as a pilot for US Airways, and obviously the "Miracle on the Hudson" but does he have any history or experience flying 737s or did they just plop ...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Did anyone you ever have a need to write lots of posts calling for better pilot training around the world for pilots UNTIL Max crashed ? Be honest ? Remind us again of the Airbus A330 design issues in the Air France fatal crash. Or the calls for better training (not me but people made them) after t...

https://www.bloomberg.com/news/articles/2019-06-14/boeing-updates-older-737-simulators-in-wake-of-fatal-max-crashes Confirmed NG simulator did not accurately reflect manual trim wheel forces.

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Can anyone confirm when MCAS was implemented. I got the idea the light control forces were noticed during flight testing. This is a bit late in the day. It leaves only one option. A software fix. Any structural or aero fix would have taken years to do. As for the higher mounted engine causing more ...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

It's about the lift the MAX's nacelles generate at high angle of attack due to complex airflow between nacelle, pylon and wing, rather than "engine too big". Obviously. But this is pedantry. The only reason the MAX has a tendancy to pitch town due to the high aoa is because they wanted to...

Ralph Nader Says Boeing 737 Max Is Flawed and Should Never Fly Again Consumer advocate Ralph Nader said the larger engines mounted to the Boeing 737 Max represented a design flaw and called for the plane to be permanently grounded. https://www.bloomberg.com/news/articles/2019-06-04/nader-says-boein...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Engineers are responsible for their design. Negligence has put engineers into prison before. Why should aircraft engineers get a special dispensation? Anyway we are not only talking about engineers. In what country have engineers gone to prison and what did they do? I am an engineer in the USA and ...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

In his interview today all he could say was the Max will be flying again by the end of the year That's twice this week he's given that as his answer when asked when the plane will be in the air again The end of the year? Another 6 months of grounding and roughly 6bn in damages to Boeing? He should ...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Mullenburg is on CNBC again right now - saying certification flight could be soon - then it needs to be approved by the regulators - has said sorry about 10x. He didn't give a definite time line - I got the impression still a few months. Did he say anything about world wide training standards or di...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

The people in this thread laying blame onto the pilots, should take a step back and have a long, hard look at the international safety standards for catastrophical failures. Which is less than one in a billion per flight hour. I will brake that number down to make it more specific. We had almost 40...
