Even though im not a developer, i am trying to move up to a leadership position in my company. Anyme i see a video from Nick, I either save to to my watch later or watch it on the spot. He does such a great job telling stories and tying into how to lead.
Oh hell yes another talk by Nick! I've been too long. I love his presentations and I can't believe the UA-cam algo isn't serving this to people. Millions of views on the skunkworks, none on this. I hope it changes.
Mr Means I flew the “weird” Avro RJ/146 you mentioned at the beginning of the talk I would pleased to tell you why it has 4 engines Now fly the Max. Could talk about it with also All the Best, Johm
I was told (when I was small) that it was to pass noise requirements at regional airports, was there any truth in that? I was also told that is was because they couldn't fit six on, so...
I recently found Nick’s Lead Dev talks and was wondering when Lead Dev is. I see this is 2022, are the talks released online a year after the conference?
First, they spin so fast that you would probably break your hand if you tried to physically stop them, and/or the clutches on the handles would slip. The best way to handle a trim runaway like that is to turn off the trim power switches, then re-trim with the handles manually. One of the items that Mr. Means did not mention as it was not central to the theme of the talk, is that Boeing had (and has) a procedure if the trim gets stuck at one end of its travel or the other. The pilots "porpoise" the aircraft in a vertical sinusoidal arc, because at the reversal point of the arc (top), the aerodynamic load on the tail is nullified, freeing the manual trim enough to get a few turns. Once this is done a few times, the air load on the tail lessens enough to continue to trim manually. But this requires specific training and an understanding of what has happened to the aircraft. Unfortunately, the crews either did not have the time and altitude to recognize and implement the procedure, or they did not have the training to do so, or both.
You missed the single biggest factor, was not the FAA, was not Boeing, these cheap and corrupt airlines in Ethiopia and Indonesia used a replacement parts from the WRONG TYPE OF AIRCRAFT, they use replacement parts from 737 NG!! that they bought in the black-market for $200. In any system if you use the wrong replacement part is obviously going to fail and on top of that the 0 hrs. of training for both crews, despite the maintenance screw up, they just needed to do a simple MANUAL trim the most basic skill of any 737 pilot. And just to correct you, the crew from Ethiopian airlines had plenty of altitude they were never too low, and you never do a trim against the air pressure, you have to release the yoke first to do a trim, again the most basic skill, but they don't know this because they had 0 hrs. of training. The Media, layers and politicians knew where the money was. They were not going to sue Lion air or Ethiopian airlines that was not profitable. Plus, blaming Boeing made for a better story.
This does not make sense. The Indonesian one was around 2 months old. There are no critical components which need to be changed on a 2 month old airplane. I doubt if there are any components at all which need a replacement after already 2 months in service. And even if it were the case that components needed replacement and both planes used the wrong replacement parts, then it would have been clear that Boeing did not had to change and improve anything on the aircraft as the reason of the crashes would be contributed to fitting wrong parts never warranted by Boeing. So if these parts were the issue, then why did Boeing need to make changes? Secondly, it is apparent that the Indonesian crew at least had plenty of flight hours on similar types in their pockets. If it is a basic skill, then it should be similar on all 737's (or perhaps even on Airbus)? And of course there is no such thing as flying an airplane with 0 hours of training.
@@santibanks Exactly you got it!! doesn't make sense, but the FACT remains that they went to Florida to buy 2-year-old used parts, the FBI raided this shop and shut it down, so this is an irrefutable FACT not my opinion, they replaced it with a 2-year-old part from the wrong airplane a 787 NG. The airline admitted this!! That Should've been case closed in any investigation without the politicians and lawyers involved. And furthermore, the airplane was under warranty so they could have gotten the parts free from Boeing in less than 24hrs. There never was anything wrong with the AOA sensor vane. But when you consider that the original AOA part is worth in the black-market $20,000 and you replaced it with one worth $200 just like the FBI found out, does it make sense now? in these poor corrupted countries, you can live for one year or buy a house with a profit of $18,800 usd. Or the cheap airlines just wanted to save the money. What is the reason this happened only in the two most corrupt nations on earth Ethiopia and Indonesia? This 737max had 8000 commercial flights in the US, Canada, Europe and China before the crash with not a single glitch. Boeing made the changes just to satisfy the politicians and the $$layers$$ and the newly appointed chief(hack) of the FAA appointed by the same corrupt politicians. After millions of test flight hours, they just came up with very minor changes, put on big ass switches so dummy pilots could notice them and demanded the obvious, that airlines train their pilots. And yes, there is such a thing as flying the airplane with 0 hrs of 737-SIMULATOR training, none of the 4 pilots that crashed had any, zero, nada, zip of 737-SIMULATOR training. The airlines admitted this!! Another case closed against the airlines. They had training in other types of aircraft but not on this one. One of the captains that crashed came directly from an Airbus to a 737 with 0 hrs. of training in a 737-SIMULATOR! Just criminal. There is nothing similar between an Airbus and a 737, you need to have completely different training, everybody outside Indonesia and Ethiopia knows this. Another FACT, admitted by the airline one of the pilots had only 230hrs total in his life, 2 months before the crash he was flying Cessnas. And in contrast one of the crews that had at least some hrs. of 737-Simulator training and knew the most basic skill of a 737-pilot, that was trimming the aircraft manually not against the airflow, managed to land safely on the previous flight before the crash with no big issues in the same aircraft that crashed later. They did this even with the WRONG PART installed, proving without a doubt that the aircraft despite the MAINTENANCE screw up had enough redundancy and was safe. You just need to do the obvious, install the correct parts and train your pilots properly.
@@santibanks It's not my theory just the facts, admitted by the airlines themselves, about not training their pilots, it is in the official report, and the FBI findings about them buying used parts in the black-market for $200, also in the official report. All this is factual not a theory. I'll say those are very credible sources instead of the fake news media.
In a well designed system, the failure of a single component should not lead to a inevitable chain of events that ends in catastrophic failure. Swiss cheese theory says that at multiple points the plane should have been saved, but wasn't due to other contributing factors. You can't lay all the blame on a single defective part.
I listen to every talk by Nick Means. His ability to break down problems through the lens of his interest in aviation. Leads to great lessons.
I listen to all of his leaddev talks atleast twice a year. He is such a good storyteller and aviation is of course amazing.
Even though im not a developer, i am trying to move up to a leadership position in my company. Anyme i see a video from Nick, I either save to to my watch later or watch it on the spot. He does such a great job telling stories and tying into how to lead.
Man, so glad to have a new talk from Nick. I absolutely love listening to all of his talks and how he ties them back into tech management.
Wonderful presentation again Mr. Means
And here we go again, Door blowing out of planes....
Oh hell yes another talk by Nick! I've been too long. I love his presentations and I can't believe the UA-cam algo isn't serving this to people. Millions of views on the skunkworks, none on this. I hope it changes.
Mr Means
I flew the “weird” Avro RJ/146 you mentioned at the beginning of the talk
I would pleased to tell you why it has 4 engines
Now fly the Max. Could talk about it with also
All the Best,
Johm
any chance you will share for the rest of us? i wanna know cuz it looks kinda goofy in a loveable way!
I was told (when I was small) that it was to pass noise requirements at regional airports, was there any truth in that? I was also told that is was because they couldn't fit six on, so...
MAXimum enjoyment.
And now the doors are falling off.
Unfortunately he might be eating those words at the end of this talk now. I laughed at the end thinking this did not age well.
I recently found Nick’s Lead Dev talks and was wondering when Lead Dev is. I see this is 2022, are the talks released online a year after the conference?
Any Boeing experts around? What would happen if one of the pilots clamped down on the trim wheels and stopped MCAS from spinning them forward?

This aged poorly
