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) Más...Sort type: [Top] [Newest]
Imagine you are in a self driving car on autopilot, admiring the view, and the cars sensors and software determine that a rapid swerve to the left is needed and the car immediately and without warning does this. You crash into oncoming traffic. Imagine there is a button or switch that can disengage the swerve function. According to Boeing, this accident is the drivers fault because you did not active the switch rapidly enough to avoid the collision. Utter crap and rubbish. Boeing is at fault, it is NOT as they claim, a training issue. The aircraft and its design was totally at fault-period.
Yes! I'm sure the pilots of US-based Max 8 and 9s have been trained on the updated operating procedures for the Angle of Attack sensor causing a Runaway Stabilizer condition (Issued Dec.11).
But the public should not have to rely on a pilot knowing what to do when a known fatal flaw happens during flight. The public should expect that the manufacturer, with oversight by the FAA, will remove the flaw so that human emergency action is not necessary just to keep the aircraft in the air.

What of the Max 9's? My understanding was that they had the same Engine placement changes that required the Angle of Attack Sensor feed. Are the Max 9's still flying?
No...all MAX's have been grounded till further notice.
Then why is the pilot even there if the passengers do not relying on him / her know what to do. There is definitely a flaw but not necessarily fatal. I strongly believe that neither flight crew applied the tried and true procedure for runaway trim that has been standard on Boeing aircraft for decades.
I'm sorry if I wasn't clear. The pilot is certainly relied on. Flying an aircraft is by definition a Complex task, meaning that things happen that are not foreseen and that the pilot must deal with in real time. (see https://en.wikipedia.org/wiki/Cynefin_framework) But known flaws in the aircraft that threaten airworthiness except for emergency recognition and then specific action by the pilot should not be in that list
Unfortunately Allan it’s worse than that. A button doesn’t stop the problem and the autopilot is off when it happens. Would two crews, particularly a second one after getting a heads up, have rode planes into the ground if a button would have given them control at anytime? The stabilizer trim system which includes MCAS ihas a serious problem and crews do not understand it.
Very first sentence in the new Operating Procedure issued in the Airworthiness Directive following Lion suggests the autopilot is on:
"Disengage autopilot and control airplane pitch attitude with control column and main electric trim as required. "
Wow.

I am getting the impression that the AP is connected during the take-off roll at the discretion of the pilot in command. I have been retired from aviation for 23 years and this is the first time i've heard of this as being a common practice. Any pilot using an AP on take-off doesn't belong in a cockpit. I can now see why there are F.o.'s with 200 flight hours working for some carriers.
Yes, it's very clear that the autopilot has nothing or little to do with this issue.
