Re: [MBZ] OT Boeing 737 Max 8 info
Heard this a.m. that they recovered the jack screw from the horizontal tail and it was trimmed to pitch the nose down. I don't agree with Grant that it is reasonable for pilots to know everything about their jet. In my experience, commercial pilots know the least, military pilots know nearly everything in the flight manual, and test pilots know a great deal more. But nobody really knows everything in the software. I recall an incident about 30 years ago where an F-16 began an uncommanded pitch oscillation (about +3g to -1g) for 10-20 secs that began during aggressive maneuvering. This oscillation stopped as suddenly and mysteriously as it began. That F-16 had a quad redundant digital flight control system and sensors and no faults were indicated. That means that all computers agreed on every calculation and the air data sensors agreed on every measurement throughout the anomaly. As far as I know, the cause was never found. I don't condemn all digital flight controls. I have seen F-16s land safely with entire control surfaces (rudder, aileron, one slab) gone. But risk tolerance in an ejection-seat jet can be a lot higher than a commercial airliner.

Re: [MBZ] OT Boeing 737 Max 8 info
If they get the flight data recorder it will have all kinds of settings and parameters recorded from which the engineers should be able to understand exactly what the airplane and pilots were doing. They can then run that through the simulators and see exactly what might have caused the problem. --FT On 3/13/19 11:51 AM, Andrew Strasfogel via Mercedes wrote: Big nagging question in my mind - how do they replicate the failure when testing?

Re: [MBZ] OT Boeing 737 Max 8 info
But, I read that this system was designed to avoid stall on takeoff which is not a good thing either. In fact it might have been in your earlier post. The new engines and the placement on the wing causes it to perform differently than previous 737s. Disable or leave it on.

Reminds me of the union shop I worked in the summer I was 18. The guys I worked with complained that they were inefficiently putting out crap, but didn't seem inclined to actually work harder, and I got leaned on a bit because I was putting out good parts too quickly until I slowed down. It was almost as bad as the Brit factory stories of the 1970's, the only thing missing was deliberate sabotage. (I guess it was more like the Soviet Union than England, nobody cared to do any more than they absolutely had to) Soon after, the company (Johnson Controls by then) told the union how far wages would have to go down to get the bottom line out of the red, and refused to negotiate any more than that for the new labor contract. The union went on strike, and Johnson closed the factory, because they were unwilling to run a factory with negative profit and the union was unwilling to do anything that would result in actual profit. I drove past it this afternoon, still empty. I think the 25th anniversary of the plant closing was this year.
