Read some stuff - Boeing was wrong in not informing of the problem. I spoke with a couple of Boeing test pilots who told me The B knew about the problem using only one attitude vane but that wasn’t all.
An attitude vane? Is that one of those tubes that stick out from the front?
...attitude vane...
You mean AOA vane?
We know Boeing test pilots, we live on an airport and have neighbors who fly 737s; my brother has been a Captain for Southwest about 20 years. None of them have characterized the issue the way that you have.
The thing that no one seems to mentioned in this or most other threads is what vertical trim is actually used for in an airplane. It is for the convenience of the pilots. When you take off you set the trim for your climb out speed. Then you trim for the speed that you want to use to get to your cruising altitude. Then you trim for cruising speed. You use your throttle for gaining or losing altitude. When you arrive at your destination you start trim your speed back using your vertical stabilizer trim for approach, downwind, base, and final. Is a pattern starting to become obvious to anyone here?
Your vertical stabilizer trim is used for speed control, so that you are not constantly having to maintain forward or backward pressure on your control yoke to maintain the speed that you want to fly at. When you have electrically assisted trim there has always been the possibility of runaway trim where the motor starts running one direction or the other and doesn't stop. That is why every electrically assisted trim control has cutout switches next to the trim wheel or wheels. Our airplane also has trim that is used to keep The wings level as you use fuel out of the wing tanks. We have one airplane that has no trim control at all.
The analysis here by non-pilots who have informed themselves by reading and watching mainstream media accounts and then looking up further information on the internet is typically so silly that it is worse the old Emily Latella bit by Gilda Radner when she was on Saturday Night Live. It is a perfect example of how people with no understanding of the basics of flight and flying an aircraft can come to conclusions that have no validity at all.
I assume that with your monicker that you have some association with flying. If so you should be able to conclude that this entire episode is mostly a sham. It is a shakedown on Boeing that threatens to make them less competitive in the aviation marketplace. It is a sham to excuse 3rd world airlines and 3rd world pilots for their incompetence and responsibility. They don't have deep pockets, so the lawyers don't want to blame them. because we have a pack of ambulance chasers hoping always to line their pockets from other people's tragedy. The ones who will pay are people who use the airlines. I suspect that the left wants to exploit this sham to try and get people to fly less, because that is one of the tenants of the global warming scam.
Every 737 pilot I have talked to said that malfunctions happen and reacting to them correctly is what they are being paid to do.
