Dear friends and followers, welcome back to my channel!
In today's video we'll be looking at the famous Boeing 737 MAX. What caused the grounding of this plane? What did Boeing do to get her certified? I'll give you a better understanding of the MCAS system. The easiest explanation on how the system works by using a bicycle! I'll briefly mention the Angle of Attack vane that caused the problems with the MCAS! Is it safe to fly this beautiful airplane again?
Thank you very much for your time! I hope you enjoy this video!
Wishing you all the best!
Your "Captain" Joe

Not just Boeing's greed. The FAA certified the A/C and yet has their sweaty fist out for $2B to pad their posh budget. Government fines do nothing to reimburse the crash victims. That requires a costly lawsuit... and it's future ticket buyers who will actually pay for all of it.

Actually, a greater focus on long-term greed would have ensured that such a murderously incompetent attempt at saving short-term money would not have been implemented. Clearly the outcome was not financially beneficial for Boeing. This has the hallmarks of woke engineering, and diversity hiring. I'd bet if you dug further into it that's what the facts would show.

I got a question and yes it might be and obvious one.... or not. Here it goes. Why didn't Boeing make the 737-MAX a rear engined plane? I get it they wanted to roll it out ASAP but the need for MCAS came from the fact that they needed a system to pitch the nose down. Those LEAP engines needed to be moved further forward throwing off the plane's Center of Gravity. I understand that creating rear engined plane would mean the wing would have had to be moved backwards since you'd have all that weight in rear. Also there's the time needed to design, and test a new T-tail - or "update" that used by the 727. At this point, you'd pretty much have a new plane altogether. However, how much of a change would it have been? How "MUCH" longer would the development and certification process have taken? Would it have been enough to justify a clean sheet design? The benefit I see is they would have been able to use the leap engines without worrying about ground clearance. Keeping the plane low to the ground meant that loading the plane would be the same as it is with the current 737 models. However, now they'd have to "reach up" to get to those engines. Would this have messed up the economics of operating such a plane to the point that it would drive away the LCC's?

Failure to include the changes in flight characteristics and MCAS system in the MAX training is absolutely criminal. The executives who greenlit this (and/or pressed for this) should be in jail.

Still the same design, still a computer making up for the design flaw with some tweaks in software and couple of new sensors. Boeing has some serious ego issues scrapping the design and designing a new aircraft that can accommodate the new larger engines but as somebody said money is more important than lives. This happens when you let corporates decide rather than engineer's.

The Max Program was really an admission the 737 Airframe had reached the end of the development curve, Boeing simply put money before safety and good design it's a shameful stain on what was once a great company.

Means that the MCAS software system has been repaired? Was the jet engine position also changed to be higher than before? Besides that, I think it really needs to be given training about that to pilots who will fly the new 737 Max? and it really needs to be explained to the public not to worry about getting on this plane

There has been a big cultural change in Boeing, away from being engineering driven and towards management / profit driven, here more more explaination: ltwindow.info/market/fXu1jdGdyNCXd6s/vaizdo-ra-as.html As a pretty good engineer, my prediction is that there will be more profits for wallstreet, but also accidents and more and more loss of reputation.

The MCAS device/design/idea/modification became faulty precisely at the point in programming and design when BOEING ERRONEOUSLY put in the manual control input override in it. THAT's the entire salient problem. The pilot by design and default is ALWAYS supposed to be able to provide the ULTIMATE control inputs in ALL BOEING planes prior to MCAS and inability to override the autopilot/trim doomed these aircraft in both specific cases WHEN the pilots simply were not able to fly the bird manually as WAS the pre-MCAS norm or understood, built-in safety standard worldwide. The solution remains in KEEPING BOEING's hallmark in avionics design that gives pilots absolute power to control their aircraft, in case of catastrophic and suspected avionics failure or misdetection in navigation or flight. But further the other design modifications that were made seem just as rushed, e.g., the short landing gear and modified engine cowlings seem to be shortsighted or beyond the design limits somehow of a craft that size, operating as it does/is expected to. I'm a total 737 MAX fan in EVERY way otherwise and it IS a dream machine - like all the great one's: B-29, F4U Corsair, Lancaster - dream come true . . . once ya ge the few bugs outta of 'em. Then comes PAYDAY.

Laminar flow is not required for a wing to generate lift. For safe flight, the wing does need a sufficient pressure gradient. A stall is not a loss of laminor flow, but an adverse pressure gradient, causing a backflow & exponential reduction of lift. Even a stalled aircraft does not drop straight down, but it does create a situation where the lift generated during a stall is unable to counter the weight of the aircraft. It also means that any control device affected by the adverse pressure gradient (for instance the ailerons on the wing) will experience a drastic reduction in control authority. This post is intended as constructive criticism & is in no part intended to undemine the otherwise excellent work done on this channel. cheers!

Prieš 13 dienų
just a note that an adverse pressure gradient has to exist over part of the upper surface of a wing - a stall occurs when flow separates because that adverse pressure gradient is too large

Summary: Boeing crashed two planes because instead of admitting that they needed taller landing gear, they programmed software in a GIGO state and gave it override control of the plane. And TOLD NO ONE. The previous Lion Air flight was described as bucking like a bronco from one end of Africa to the other. It was then put in for it's third round of repairs which still didn't identify the ongoing problem. Ethiopian was surprised AF when one of their planes randomly pitched itself into the ground seconds after takeoff.

The decades old competition between Boeing and Airbus has two sides. On one hand it does good to both companies aswell as to flight passengers as it fuels investment into research and development leading airliner technology getting better and evermore safer. Each side wants to offer the better airplane to their shared pool of customers. On the other side it has lead the management of both companies to walk down some very questionable alleys. Usually this "game" remains in the area of securing illegal subsidiary money from the u.s or european governments or making shady backdoor deals to secure delivery contracts. But what happened with the MAX has certainly crossed the line. Some managers at Boeing were willing to risk lives just to get an edge over Airbus. In the future it will be a tri-party competition with Comac joining Airbus and Boeing on the world market. We will see how hard the game will become then.

I will be avoiding this model in the future. It's not just MCAS; it's the unstable engine layout that requires it. This plane needs to be removed from service permanently.
Appable
Prieš 13 dienų
@Byron Jones MCAS doesn't do anything with elevator control, it modifies the stabilizer trim (in the same way that STS does, and using the same hardware as the electric trim system). 737 MAX is not unstable in the sense of fighter aircraft, by the way. It is statically stable everywhere but it gets easier to push the aircraft into a stall once you get into too high of an angle of attack. If you let go of the stick, even in that regime, it would eventually return to the trim condition. As mentioned though, MCAS as a concept is not a problem. Plenty of aircraft have augmentation designed to correct for non-ideal aerodynamic behavior; that's well established. Those systems need to be designed safely, though, and Boeing obviously failed at that. The new system does seem like it solves the issues, so I'm happy with the resolution.
Byron Jones
Prieš 14 dienų
@Kalle K it absolutely has the ability to control the inputs from the pilot. If it didn't the accidents wouldn't have occurred. So yes, it is absolutely, positively, a "stick pusher".
Kalle K
Prieš 14 dienų
@Byron Jones Wrong again. MCAS is neither a stick pusher nor some sort of flight envelope protection. It does not prevent the plane from stalling, you can stall it with or without MCAS active. Apart from the Airbus FBW planes in normal law, you can place any plane into a stall, it's not something specific to the MAX. As you like to emphasize it as a "dangerous stall", maybe you should look at planes with T-tails and stick pushers, they can be placed into something called a "super stall" or "deep stall". The MAX doesn't stall like that.
Kalle K
Prieš 14 dienų
@Byron Jones Never did I say that MCAS wasn't the cause (it was, otherwise it wouldn't have had to be redesigned). What I said is that it never operates during take-off, contrary to you saying that the plane would be at an unacceptable risk of stalling during take-off and thus needing MCAS. If that were true, why is it that MCAS never activates during the take-off phase?
Byron Jones
Prieš 16 dienų
@Frank Silvers I never said that there are no safe aircraft with unstable flight characteristics. There have been such for decades. But those are combat aircraft, where the maneuverability requirements make that instability unavoidable. But that simply doesn't apply to commercial passenger aircraft. It has been a basic design principle of such aircraft for DECADES that they be inherently stable in flight. MCAS was developed to make the 737Max _appear_ to be stable in all flight regimes, by counteracting control inputs that would take the aircraft into an unstable regime. Without MCAS, the plane can be placed into a dangerous stall. As long as MCAS is working, the plane is safe. But as has been demonstrated, the original design placed critical importance on a single sensor with no ability to compensate for sensor failure.

@CaptainJoe, your comparison with the bag on the luggage rack is not right. The pitch up momentum is mainly caused because of the aerodynamic characteristics due to the position of the engines. The thrust vector is roughly on the same spot as on the cfm56 on the NG. Therefore the pitch momentum, M = F x R, is roughly the same.

Boeing's fine won't replace the lives that were needlessly lost. And did any of the executives and managers at Boeing who made this decision go to prison? Nope. It's ok if people die, we don't matter anyway - not to corporations. Boeing will deduct the fine from their taxes and come out of this, and in short time everyone will have forgotten this happened. And then they'll do it again.

Ah, the proverbial "corporate greed." From now on, no complaining about high ticket prices and low wages. Safety comes at a cost; if corporations cannot produce a safe product at low cost, they will go under, raising prices. Again, safety will eventually cost you. Corporate greed is your greed also.
