I’ve seen similar roll movements but never that kind of pitch movement.I don't think a pilot would be shaking the yoke that much even in turbulence. Isn't that much over control input hard on the control linkage?
Yes they do, although technology is such that they could run without them. It will be a long time before the unions and the government allow trains to run without someone on board.Does the rail industry still employ locomotive engineers in train cabs?

Halfway through our flight, the remote operator on the ground told Olson that the navigation system guiding the aircraft was slightly off. It was likely why the aircraft wasn't exactly lined up with the runway centerline on takeoff.
It wasn't life or death but system reset was recommended and Olson was forced to take manual control for a few minutes while it was reset. It was a chance for Olson to familiarize himself with flying the self-flying plane.
It may be the future but I don’t think it happens in my lifetime.
... Someone in finance will have decided to save money, the same computer and network will fly the plane and do the in-flight entertainment.
Who said anything about Hollywood? Think Colonial.good luck getting such an architecture certified.
Fortunately, there are times when hollywood doesn't match reality.
Anytime you see cockpit shots of the Caravan flying. 19 seconds in is the first example.At what point in the video is that?
Think DO-178, with which the oil and gas industry does not comply.Who said anything about Hollywood? Think Colonial.

...and IFE has already brought down at least one piloted airplane.
Someone is going to think that's what I was referring to.Yep.
Colonial didn't have to have the system get any airworthiness certification.
You guys are too trusting. Companies will cost costs where they can. Boeing 737Max, anyone? There's a whole thread on that, somewhere on PoA.Think DO-178, with which the oil and gas industry does not comply.

...not by a long shot, but I do understand what design, validation, and vertification of flight critical software entail. I don't think the same can be said about a lot of people insisting it is doomed to fail.You guys are too trusting.
... The standard is that they must not get it wrong.

I agree that this is an informal goal for flight critical software. It has never been the standard for pilots and pilot training, and we all accept that without blinking.I've said it many times - the standard is not that they can get it right. The standard is that they must not get it wrong.
Based on the 737 MAX fiasco, is FAA certification really all that high a bar?good luck getting such an architecture certified.

Take a look at CFR14 part 25, DO-178, DO-160, etc...Based on the 737 MAX fiasco, if FAA certification really all that high a bar?

If it does not become the formal goal, they will fall short of the required safety standard.
There are certainly thing software can do better, but if the software fails in simple things, it is unacceptable. Say for example, ordering nose down trim that results in a crash in VFR conditions because it doesn’t recognize a failed sensor.
I will repeat, the software must not get it wrong. It must be capable of detecting errant data and resolve what’s correct, and do it with less sensory input than a human has. It must not follow a single or even multiple data point into a crash.
Unfortunately, you weren't one of the people at Boeing, as I'm sure it would have been done correctly. I'm not being sarcastic, and I'm not being patronizing. I won't even pretend to know anything about flight critical software....not by a long shot, but I do understand what design, validation, and vertification of flight critical software entail. I don't think the same can be said about a lot of people insisting it is doomed to fail.

Could be, but if that doesn't doom them, my bet is that weather will....Stupid management tricks will doom autonomous planes, not the technology.
Your desired "formal goal" is not actually the formal safety standard for airworthiness.
look at the latest revisions to AC 25.1309; AC 23.1309; AC 20-115
the difference between strategic and tactical.
I believe the goal is loosely encoded in the AC under failure modes. The system designers must be depended upon to catch every interaction and determine the correct severity. That is requiring them to not be wrong without stating it as a principal.
I wish all of the FAA had that mentality.Not quite - the standard is that the probability of getting it wrong is acceptably low.
Note that zero is simply not possible.
no, the difference between good enough and perfect.
I guess I'm getting hung up your use of "every" and "all" and "perfect"... your use of absolute terms.
so it’s ok if system designers let some data interactions go through without understanding them? I meant, if it is only a few interactions, there can’t be a safety risk, right?
perfect IS the goal when it comes to not failing because to say otherwise is acceptance of automated failure.
well, perfect is the "goal", but perfect is not the requirement.
What is the acceptable probability of a failure leading to a catastrophic loss of an aircraft and all souls on board? (I think you can find that in AC 25.1309 and/or 23.1309 - it's been a few years since I've looked at them - after all, I AM retired)
