Trump Announces Ban of Boeing 737 MAX Flights
President Trump announced that the United States was grounding Boeing’s 737 Max aircraft, reversing an earlier decision by American regulators to keep the jets flying in the wake of a second deadly crash involving one of the jets in Ethiopia. (www.nytimes.com) Mais...Sort type: [Top] [Newest]
And yet another post that should be relegated to a political forum...
i am somewhat disgusted with both AA and Southwest who continued to fly these planes until they were grounded by executive order. American even made passengers who wanted to change plane types to pay the change fees. Do they have that little concern for their customers? I would have thought that the liability risk if something had happened to another plane could have bankrupted the company.
According to latest FA data, there are three 737 MAX flying right now....
A quick fix would be a flaps 1 position prior to takeoff as part of the checklist and then going to flaps zero at 2oo kts. I think that going from 15-25 degrees of flaps at takeoff could be causing this onset of stick pusher when the flaps go to zero in a stabilized nose-up attitude. I'm not a pilot but I am a professional spacecraft/aircraft simulator individual who spent 31 years at American's simulator department as a problem solver. I also was deep into the Boeing product line.
You're thinking there Ron. Generally if the aircraft does something unexpected right after performing some action, you should immediately undo that action. Supposedly the MCAS is disabled with flap deployment but may be sitting there with an erroneous input ready to start doing its thing upon flap retraction. If the crew brings the flaps up close to max speed for that setting and continues to accelerate past that speed they may be hesitant to put them back down and the problem grows.

Just read an interesting article explaining why the MCAS system is necessary on the Max. I'm not advocating this as the cause of the recent Ethiopian crash, just raising it as a possibly. The 737 was originally designed to be low to the ground to accommodate air stairs before the prolific use of jetways. In its efforts to make the 737 more fuel efficient, and to compete with Airbus, the designers had to modify the design to allow installation of the new large diameter engines while still maintaining a minimal ground clearance. This caused changes in the aerodynamics forcing the designers t implement this automated system which detects excessive pitch up and forces the nose back down. Apparently this MCAS malfunctioned on the Lion Air flight last year resulting in that crash.
I've said for years that it's time for Boeing to create a brand new single-aisle 737 replacement to compete with Airbus' A32X series. The new A321s are even viable replacements for the 757s. Instead all Boeing decides to do is make yet another "upgraded" 737 variant. Boeing needs to stop trying to do things on the cheap and get serious about creating 21st century aircraft that can outperform and outsell anything that heavily subsidized Airbus can put out. My advice would be to focus heavily on the new mid-sized 797 that they've proposed. Airline traffic is going to increase greatly in the future and even short domestic flights will need to use higher capacity aircraft in order to be efficient.
