We learned long ago that the leading cause of airplane accidents was pilot error. A human made a mistake and the plane crashed. So we started trying to figure out how to eliminate human error. In the process, we have learned the wrong lessons. As usual for humanity.

There are so many examples of a fine pilot managing to pull off a “miracle” landing after an incident. Saving most if not all the lives of the passengers. Yet, those stories are getting fewer and farther between because one truth is coming home to roost. The effort to remove Human Error from the equation, has removed humans from the equation. The old school stick and rudder pilot who manages the emergency and saves the lives is essentially gone from our cockpits. Now, it is systems managers, IT professionals who hopefully understand the computer that is actually flying the plane.

Prosecutors, Transportation Department Scrutinize Development of Boeing’s 737 MAX

Prosecutors want to know how the 737 Max was approved. Well. It was designed and built, and approved the way it was for a simple reason. The airplane manufacturer is supposed to make planes that almost fly themselves. In the old days, if you had a pilot with 10,000 hours of flight time, you had a lot of experience in those hands. Today, that pilot with 10k hours has perhaps a couple hundred actually flying a plane, the rest is sitting there theoretically monitoring the computer. When an emergency happens, the pilot screws up, despite all the experience, because that experience is a lie. They don’t have 10k hours flying. They have a couple hundred hours flying a plane, the rest might as well be time commuting.

Accident after accident, event after event has shown this to be true. The Asiana Airline crash into San Francisco. The Pilots were not supposed to fly the plane by hand ever according to the airline. So they screwed up, and crashed. The Air France crash in the Atlantic. The pilots encountered the one in a million event and couldn’t fly the plane.

The problem with automation is that the humans become dependent. They expect it to work. They expect it to work and when it fails, they are at a loss as to what is supposed to happen.

Yes the automation does reduce the number of “human error” accidents, but it also guarantees that nearly any failure of the automation, will result in an accident where human error is a major contributing factor. Because the individuals sitting in the cockpit are not pilots, they are computer technicians who are just the most forward sitting passengers on the aircraft.

We’ve learned the wrong lesson. Instead of realizing that training and more training is the answer, we decided to eliminate the human error, by eliminating the human. Boeing is not more or less responsible than any other company. They just went with the same trend that everyone else has, because that is what the customer, and the people expect. We believe we can make the automation perfect, and in doing so, make the accidents stop. We are not perfect beings and anything we make, will never be perfect. Airbus has also had automation issues, as have pretty much all the manufacturers. Automation is supposed to ease the load on the pilot, allowing them to be more aware of the big picture. Instead, it is used to make the humans superfluous. And we don’t train things we don’t need, or people we don’t need. This is the result.
 
....yes---since most are pilot error-
..on 2 well known crashes the pitot tubes provided wrong airspeed--so when the plane was stalling, the pilots did not ''know'' it--even though the STALL warning went off numerous times--also both pilots had control of the aircraft at the same time in the Air France crash
Air France Flight 447 - Wikipedia
that adhesive tape had been accidentally left over some or all of the static ports
Aeroperú Flight 603 - Wikipedia
..so Boeing tries to get rid of the stalls--which was not the problem
my question is did the plane manufacturers fix the pitot tube/etc problems?

The Pitot tubes were already slated for replacement when the Air France accident happened. A newer one with improved heating elements to reduce/eliminate the chance of icing of the tubes at high altitude.

The problem is that the pilot expects the computer to fly the plane. When the computer fails, as in Air France 447, the pilot’s first actions, the vital first few moments, or minutes, is spent trying to get the computer back on the job. The pilot isn’t a pilot in that case, but a poorly trained technical support individual.

Air Transat Flight 236 - Wikipedia

That incident is a good example. You had two really good pilots in the cockpit. Yet their first actions were to manage the computer, instead of doing what any pilot would have done in bygone years. The fuel was leaking out. The alarm sounded telling them of unequal amounts of fuel in the wings. The pilots checked the book, and found the answer was to equalize the amounts of fuel. More precious gas left the wing as the alarm sounded again. By now, they are starting to wonder, but they equalize the fuel again. The book didn’t have a paragraph telling them to wonder where the fuel was going. By the time they did, they ended up gliding in to a landing. The pilots were to be congratulated for managing an emergency unpowered landing. But they were also blamed for not suspecting a fuel leak until it was far too late.

The incident could have been avoided by the time the first fuel inequality alarm went off. The Pilots could have done some math, and come up with the truth that they were losing fuel at a rate of one gallon per second. They could have shut down engine one, and made it to a much safer single engine landing. A lot of luck meant that they had an airport in range when they ran out of fuel. That luck did not mean they were good pilots, it just meant they were sufficient. Their initial action was to trust the plane and the manual, and not wonder why the alarms went off, because they weren’t told to wonder why by the book.

Anytime something happens with equipment I am operating, something I haven’t seen before, or very often, I wonder why. I keep an eye on it, and check to see what is really going on. I refuse to kill someone or injure them by accident.

15:59:58 F/O God, look at that thing. That don't seem right, does it? Uh, that's not right
16:00:09 CA Yes it is, there's eighty
the FO is talking about the engine readings being wrong--yes?? and they were not, I thought
