What are people going to fly instead? The regular 737? Have you seen the list of how many 737 crashes there have been? https://en.wikipedia.org/wiki/List_of_accidents_and_incident... Or maybe A320 https://en.wikipedia.org/wiki/List_of_accidents_and_incident...

> Through 2015, the Airbus A320 family has experienced 0.12 fatal hull-loss accidents for every million takeoffs, and 0.26 total hull-loss accidents for every million takeoffs; one of the lowest fatality rates of any airliner.[3]

I’d take an A320 over a 737 every day, the latter seems so cramped and a little older, to be honest. Or maybe me only experiencing them on Ryanair made me think that way.

Earlier quoted context omitted.

Just curious, what would it take for you to get on a 737-Max? European and American regulators have gone over it with a fine tooth comb at this point and allow it to fly. There is always gonna be people that will say the plane shouldn't fly. Arguably the amount of attention this plane has gotten will probably make it one of the safest in the industry going forward.

Is it not an intrinsically imbalanced aircraft?

No it is not. No regulators has yet been prepared to certify a fixed-wing aircraft that is intrinsically unstable, even after decades of proven fly-by-wire development.

The 737 Max has different yoke force during pitch-up than predecessor 737 models, such that at higher angles of attack it does not natively require increasing yoke force to continue to pitch up. That doesn't mean it would pitch up uncontrollably. MCAS was designed to provide pitch-down force in these high-AoA cases so that yoke forces would be equivalent to 737 NG models and minimal training would be necessary to fly both.

But its not?

But it is? I think the parent was talking about: >Travis is unequivocal in his assessment of the Boeing 737 MAX. “It’s a faulty airframe. You’ve got to fix the airframe [and] you can’t fix the airframe without moving the engines” back and away from their current position. >The root problem with the engine-forward design is “once this thing pitches up, it wants to keep pitching up,” said Travis. “That’s a big no-no,”…

FYI - Background on the guy being quoted

"Gregory Travis, a veteran software engineer and experienced, instrument-rated pilot who has flown aircraft simulators as large as the Boeing 757"

I know a few veteran software engineers that are instrument-rated and frankly I'm not sure I would listen to any of them over the FAA or aeronautical engineers. Probably good for some perspective, but not exactly a great source for determining if an airplane is "aerodynamically flawed by design".

I’m at a point where I just opt for carriers with Airbus fleets. I do not trust modern day American corporations nor the oversight bodies. There are too many financial incentives to cut corners.

For years after AF447 I was nervous flying airbus. In reality, it's extremely unlikely that you'll die flying.

(I'd be nervous flying a Max too, but it's not rational.)

737Max is certainly tainted now. But will that last forever? And do non-HN-aviation-geek consumers really care enough to check the model of the plane they'll be flying on, let alone make a flight decision based on the model? Certainly another crash could be devastating to the model. But was the 737Max a poorly designed death trap rushed to production or a super safe airplane with a single fatal flaw? Time will tell..…

Certianlly not just a single flaw. They found and fixed multiple other flaws while checking though everything for re-certification. In my opinion, the 737Max is probably one of the safest planes right now, simply because of the amount of scrutiny it's been though.

Unless, of course, it was fixed and scrutinised by organisations which still have the same systemic flaws as the first time around.

Until the sociotechnical systems that do the work change, they will keep overlooking problems and making similar mistakes, from a high-level perspective.

In my experience the non aviation geeks are also worried about 737 Max’s.

That’s validated by the fact that the involved companies are referring to it as the 737-8 instead, which will not fool anyone who knows anything about aviation and is geared entirely towards ordinary people.

Since the plane is aerodynamically flawed by design. I'll never step foot on one.

Aerospace controls engineer here - while the airframe might not be passively stable (as is common for civilian aircraft), dynamically unstable aircraft have been stabilized with control software since the 70s [0]. If you've flown on an MD-11, you've flown on an 'aerodynamically flawed' aircraft. Most real systems are dynamically unstable without some kind of controller (implying software) in the loop.

Both have many variants and many ages. It’s just Ryanair.

This has gone beyond aviation enthusiasts. I think you will find a not insignificant number of regular people who are skittish about flying on a Max.

Would love to know how many more clicks there are on flight details on booking websites once Max returns.
