Maggie's Farm

We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.

Trim tabs


Boats and airplanes have trim tabs.  How they work is a bit complicated, but they make operating a machine much easier. 


This is about trim tabs and the Boeing 737 Max problems, "This aircraft should not have been built":

The 737 up to the max has a great safety record. Not sure what this guy is babbling on about. Second, I know 2 pilots that love the max and think it is safe but they are also great pilots flying for an american airline. I agree Boeing messed up on the design but a few quick fixes and this plane should be good to go. They should make the next one a little bit wider IMO.

Very interesting. Thanks!

I don't have confirmation of this, but a fiance of a family member is a pilot, ex-military, who now flies for an airline with lots of 737's. He told me over a beer that this MCAS control system that is at the center of the controversy can actually be disabled by throwing a switch once it starts to act up. The case of the foreign pilots fighting the system into the ground, as described in the video, happened because they hadn't been adequately briefed to anticipate the problem, understand what was happening, and then overriding the system by disengaging it.

Boeing has lost its way in my opinion, as many industries have, by moving management away from the production line and the influence of their engineers, giving the reins over to the bean counters who ride according to the targets on the quarterly report.

Trim tabs work for the same reason that air doesn't just blow out the front of jet engines.

Leverage.

See http://archive.is/vYmHZ, an archived article written by William Langewiesche, for insight into flight training by some foreign airlines. And no, I don’t have Boeing stock, but I wonder if the guy who posted the video has Airbus stock. Langewiesche is a well-informed pilot and a great writer.

There's a question that nobody is asking: How many commercial jets do we really need? Since the 747 revolutionized international air travel decades ago, almost every place in the world has been over-run with tourists. As an example, Mount Everest now looks like a garbage dump, populated with hundreds of climbers. You can be sure that other places will be destroyed in the future by "eco-tourism". The Galapagos, New Guinea, Ecuador, etc. I think that we need to take a look at how tourism adversely effects foreign people, and natural areas. Maybe it's time to reduce global tourism. People can be left to live in peace, and all of our natural areas can be given time to recover.

I'd rather fly on a 737MAX with American pilots than ANY plane flown by 3rd world trained pilots.

With others I agree, wouldn’t happen to a US pilot. In any case uncle sugar always has a couple of contracts to through Mamma B just in case. That case is here already. WuHan19.
