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

Unfortunately Boeing has had too many fuck ups in recent years for me to accept any of their statements. During my time in the U.S. Army as an Aircraft Structure Repairer, Boeing released a new Apache Gunship. They were plagued with problems and killed a few crews. Thankfully my unit had not yet received one of these new birds, but I am still upset that they died over rotor head related issues. (Apaches have had similar issues in the past, but were mostly fixed in the Delta models.) After "fixing" the issues AGAIN... Our sister Battalion's fleet was grounded once again due to persistent electrical problems outside of the norms. I refuse to fly on another Boeing other than the CH-47 Chinook.

I consider it both a catastrophe and a symptom of our time that computers are programmed to think they are smarter than the people who operate them. It reminds me of my windows PC. "You don't have permission to access this folder". WTF, I own you, you st*pid machine! I paid money for you, so you don't tell me which folders I am allowed to access! Furthermore, Boeing violated a basic principle of aviation: the pilot, NOT the software, has to have the final decision.

Correct. The MAX version numbers don't end in "...hundred", they're the -7, -8, -9 and -10 (of which currently only the -8 and -9 are flying). 737-600 through -900 are the NGs.

I always prefer to pay more for peace of mind and comfort. I don't like flying but I have no choice. I will go out of my may to avoid flying on a Max, you will never see me on that deathtrap, no matter the time, missed appointments or extra cost. Trust in the airline and manufacturer is what keeps me calm and comfortable during a flight. Last couple of (long haul) flights I chose Singapore airlines because of their A350. It was a less convenient time and airport for me, but KLM had a Boeing on their route, better times, less money but I won't fly them. Before I will be flying Boeing they need to prove that safety comes over money again. Knowing they, as an aircract manufacturer, chose money over safety results in me losing all confidence and not flying them the next years.

Why don't you show again the diagram presented of the Boeing 737 800 at time 6'00" again with the new 737 max later? ? ? You would make it that way easier to understand... why don't you show the lever arm of the 737 max resulting by putting the engine in front of the wing instead of below as with the B737 800. Good day.

I do feel as you do that The Boeing Company has done huge harm to itself which may take some time to put right.

Will you please do a video explaining the full story of DHL 611 Uberlingen Mid Air collision. At lot of people blame the Skywise company for putting the air traffic controller under stress but now I was reading that ATC is trained to deal with that and it was negligence of Peter Nielsen for prioritizing an Airbus rather than ensuring his air space was clear of any conflict.

Deathtrap, it's 40 years old. It is not designed for the engines fancase size. Board of directors were thinking about their yearly bonuses not about anyone's lives. The most important characteristic you want in a cargo hauler?> STABILITY! If you need 2 computers to keep your airframe stable IT BETTER SAY F-22 OR F-35 ON IT'S SIDE. The MC-21-300 in the airframe Boeing should have built.

B-737 MAX is still unbalance because of the placement of the engines. Why don't just Boeing company add some ballast weight to recalibrate the centre of gravity? I know it would affect the engine performance but still better than MCAS I suppose.
Kalle K
Kalle K پیش 4 روز
It's done on every flight. The ballast is called "passengers, cargo, fuel". They all shift the CG around. But even without pax, cargo and fuel the CG has to be within its limits. An unbalanced plane wouldn't be allowed to fly.

It starts with the same old wrong story that has been around for ages. They even compare the MAX to the original 737, however the engines were already moved forward on the 737 classic starting with the -300 in 1984. The CFM56 couldn't be mounted the same way as the JT8D. The animation is also wrong, MCAS doesn't deflect the elevators, it moves the whole horizontal stabilizer. But she also said that MCAS has been fixed. About the quality control I don't know, but it would affect other models, like the 787 for example, and wouldn't be limited to the 737 MAX.

The Irony is that the 737-Max is PERFECTLY SAFE to fly without MCAS. The pitch up behavior is no worse than with jets like the 757. If the 737-Max was a new airplane the MCAS is a totally unnecessary system; it would be perfectly fine as it was. MCAS was there exclusively to make the 737-Max mimic the flight characteristics of the previous 737-NG family almost exactly. This was important to reduce retraining of the crew from the previous generation to the Max generation and make it more attractive to existing 737 operators.

If there is one industry I trust to design, test, build and operate airliners with Passenger Safety as Priority One--it is companies exemplified by Boeing, and the dedication of Airline Crews flying with the major airlines. If exemplary airline crews and accident investigators like Captains Sullenberger & Skiles may be encouraged to regularly contribute their leadership and experience to corporate decision-making from this point, airplane orders may increase, and public trust in an historically trustworthy industry will return.

You didn't mention - did Boeing add a redundant AoA sensor and input to the MCAS, along with some way to alert the flight deck about a sensor disagreement if it occurred? And I wonder if maybe Boeing ought to take a good hard look at what's become of their corporate culture and move the corporate offices back to Seattle, where the hands-dirty people can have better access and input to the pencil-pushers?
Kalle K
Kalle K پیش 5 روز
They reprogrammed MCAS to take inputs from both AoA sensors at all times. No sensor was added, the 737 MAX (all 737s in fact) has always had two. The bug causing the AoA Disagreement alert not to be displayed has also been taken care of, it's working again on all 737 MAXes just like it did on the NG.

Airbus had a similar incident with Qantas 72. Faulty AOA data got fed to the flight computer, the Airbus automation commanded a 10 degrees pitch down multiple times despite the flight characteristics being fine and not need any of the protection modes. AFSB findings led to Airbus modifying their software to prevent bad AOA data causing an event like that again, but the cause of the AOA data being bad in the first place was never found. Scary sometimes, no matter how sophisticated the software automation is now, there's always an edge case somewhere. Granted MCAS on 737 MAX had many more factors and deception and corporate greed is right up there. RIP to those who were victims of Boeing's failures.

It's doesn't make me sad... It makes me angry. Boeing had always been known for building planes with superior pilot feedback and flyability. They sold a product that undermined that, AND DIDN'T TELL ANYONE, just to make a profit faster. I'm sure the CEO and his team will at BEST get Golden Parachutes, but they DESERVE a sentence of a decade of community service on minimum wage.

One wonders how test pilots missed this. One also wonders how the systems on the plane didn’t sound the alarm on sensor values that would obviously conflict with actual operating parameters. Also, given the A320’s well known propensity for presenting pilots with confusing data that required them to recalculate or override something, wouldn’t pilots be reporting such things as having to manually trim a computer-controlled aircraft? Not laying blame, just wondering.

What was most poignant about this whole affair (at least to me) was that at the same time shitty electronics and even shittier programming caused so much deaths in the MAX, Boeing *also* fucked up their code and electronics on their Starliner test flight. I really hope that heads did roll in their management for those fuck-ups and, more importantly, that they - and all their competitors! - learn from it.

Airbus is pumping them out as fast as they can but if you go buy an A320 you'll still be in a waiting list. Also If your already in line for the 737 and your tooled up for the 737 line up it's quicker and less expensive to stay with the 737 platform

Why didnt the pilots just disable the entire MCAS system when they realized it was malfunctioning? wasnt that an option of the boeing??? did they not know how to operate the features of the aircraft???
Stop Telling Me What To Write
Was not a defeatable system -"computer knows best"... Boeing purposely skipped mcas training because that would indicate major system change and therefore requiring a lengthy recertification (and times is $$$); gamble ended up costing more time and $$$ though...and bunch of dead people.
