Boeing's 737Max has been released for pax service after the longest grounding in US history.
Is it safe now?
Would you fly on it?
Why?

Yeah, I tend to agree. After years of working on Boeing's, I trust 'em. I'm still baffled as to why they never put some redundancy into the MCAS in the first place...Yes. I would fly on one. Why? Boeng says it's fixed. Even before the grounding, they were flown 1000s of hours in service. Now they are improved .

Maneuvering Characteristics Augmentation System. It's a fancy name for a control law that prevents stalls. Boeing was adamant in claiming it wasn't a stall prevention system. Their reason for that was it would create more regulatory hoops to jump through. We can boil the whole thing down to Boeing sold the airplane claiming no additional training for pilots current in older 737's. That was a strong selling point to the airlines. Adding the MCAS was necessary because flight testing showed some undesirable pitch characteristics... not dangerous, just undesirable. Calling it an additional system would have required additional pilot training. That would have killed their sales pitch of no additional crew training so they just called it a control law enhancement that was run in the background and required no additional training. The fatal flaw was the lack of redundancy... it only had 1 sensor to monitor AOA (pitch angle relative to airflow). If that (falsely) detected too high an AOA, it pushed the nose down. Since crews were never trained on it, hell, they didn't even know it existed, they didn't know how to override it.MCAS ????
Actually Doug, they could override it before and could have prevented both crashes.... but you can't override a system you don't even know is there. And that's the mind blowing part of all of this. All else being equal, a few hours of simulator training and we wouldn't be talking about it.... the crashes never would have happened.I was reading the pilots couldn't override the system before where as now the pilots can.
Overriding it would have involved simply deactivating the electric trim motor on theSorry, i read this as the pilots could not over ride MCAS system. The system overrode the pilots controls, or is this article wrong......

The new software now requires inputs from two sensors in order to activate the software. Boeing says the software also does not override the pilot's controls like it did in the past.

.... I guess you could really just boil it down to Marketing taking precedent over Operations.
Yep. Love it or hate it.. capitalism in action. Someone has to mind the bottom line. The problem comes in when theirs is the loudest voice.Sadly decisions driven by the bottom line....all to common and generally bad outcomes
If you fly first class it's a lot more enjoyable.Frankly, I hate flying. Not for fear of it, I just hate the whole experience, the airports, the crowds, shuttle buses, security checks, luggage carousels and worst of all, being crammed in like sardines in those too tiny seats with the back of the seat in front of you right in your face and the interminable waits on the tarmac to take off, the last flight I took, we waited longer to take off than the flight lasted! I honestly cannot imagine ever getting on another plane. I’d rather spend three days driving to get somewhere.
I think I’m turning into a curmudgeon.
