Re: Boeing 737MAX Grounded Worldwide Q2 2019

As predicted. Boeing and the FAA are already well established bedfellows, so it'll get rubber stamped and back in US service pretty quickly. The rest of the world however will be placing greater value on people's lives and will be scrutinizing the MAX much more than Boeing (since the FAA delegates)...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

It was the job of Boeing and the FAA to explain the working of MCAS and how one has to react in detail, BEFORE the first accident. It was the job of Boeing to include MCAS into the 737MAX simulator design. It is was the job of the FAA and Boeing to design robust training routines for MCAS. In this ...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

The evolution of airspeed is a result of the nose down trim MCAS action Wrong. It is the result of a crew in an horrible situation who didn't monitor their speed, care or know to turn off the auto-throttle. Boeing can thrive on this gross negligence. Thrust has far less influence on speed than pitc...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

You are making blind assumptions, both those pilots had in total 10k hours of flying time between them (over a year in the air). What experience do you have ? About 90K hours of Part 25 airplane design & performance, safety and certification experience. While I agree that Boeing had a major rol...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Your valid procedure, I assume the runaway trim procedure, seems to be a simple joke. Auto throttle off, electrical trim off gives you an unflyable frame, because manual trim will not work without the roller coaster maneuver and for that you need plenty of height above ground. Failure with training...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

Again just pitching general references with zero specific is totally pointless. There are all specific to the 737-8/9 MAX grounding and the analysis to understand what happened at Boeing and the FAA. If you are unable to analyse not even a single information on those list of documents, nor in any o...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

There never was trained in that situation. As an amateur, thanks to AF447, I learnt 10 years ago that in doubt of reliable speed, thrust should be set at 80% (for an Airbus admittedly). ET302 was at 94%, seriously over speeding for that altitude and penalizing their ability to manually trim, ... an...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

I still don't get why a 'minor' system couldn't be fed with two sensors because of the fear of additional training. There is an equation done that need to be proved. I understand that MCAS was introduced that way, but the focus here is about 1 vs 2 sensors. Is there any regulatory stuff to support t...

Re: Boeing 737MAX Grounded Worldwide Q2 2019

The ET crew seems to have turned off the electric trim before counteracting MCAS due to a misunderstanding or misapplication of the procedure. Either way, since it was recoverable, and relatively simply so, MCAS is not the worst design in modern aviation. The tendency for some people to exaggerate ...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

From the best we can tell from the FDR and CVR, ET302 did attempt to trim the plane manually with the trim wheel, unsuccessfully. ... possibly because of overspeed? Were they aware that it couldn't be done at 300-350 knots (without the roller coaster option maybe) is a good question. Is it common k...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Newbie question here. I checked on google, trying to understand the purpose of trimming vs the nose-heavy nature of the 737 MAX. Why just pulling on the yoke wouldn't raise the nose via rear elevators? Sorry, it must be obvious for the pros.

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Than came the revelation about the certification and Boeing holding MCAS secret from the pilots. IMO that was criminal too. But did they really follow the procedures? MCAS won't kick in until fraps fully in. Why they chose to retract them quickly is matter of debate. Overspeed is a reason why trimm...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Is that correct that if the pilot would have extended the flaps minimally, the MCAS couldn't have kicked in? Some people just loves to push the r*ce button. Not the way to stay objective. It is a fact that those two crashes happened out of western world. Most the MAX flights happened in North Americ...
