Boeing does not design or build the engines, so unrelated in my view. Yes, 3WE, agree with the perceived stall confusion. Maybe they thought they'd entered the MCAS alternate universe and trusted the system over their primary senses. Again, it's hard to imagine the scensory overload when stall warni...

Unlike almost every other accident, there is a conspicuos absence of 'a missile and explosion' witness statement at the beginning of the flight where problems started. It still seems unusual for all those marks to be in one direction, but that is no reason to hang on to a completely unsupported the...

Unlike almost every other accident, there is a conspicuos absence of 'a missile and explosion' at the beginning of the flight were problems started. It still seems unusual for all those marks to be in one direction, but that is no reason to hang on to a completely unsupported theory after recorders ...

It goes without saying that I was completely wrong in my observations and interpretation of that damaged fuz section. Sorry if that mislead anyone. I'm still very interested to find out how the punctures came about during the impact, but I don't do ignorant conspiracy theory games so will wait for t...

I sent the crew a note with ITS's number if they have a problem.
Must have worked since I've arrived safely in Chile.

Just hand out parachutes until they can get some duct tape on the sensors. That way you can just point it to its destination and save on pilot training.

There is another incident that may have a small bearing on MCAS. How does it handle at the limits of CG position? Let's say for some bizarre reason the aircraft is loaded at the fed CG limit (16% ish depending on act wgt) But because of notional weights the fat dudes and heavier bags were up front o...

I believe the MCAS links to the system that automatically adjusts stab angle, which if subject to runaway is beyond the authority of the elevator to overcome, If it were linked to the balance tab, it would provide strong forces to the stick enough to counter the effects of the big engines and placem...

That's a very good response Gabriel. Agree with everything. A little addition to the 737 system: There is also a balance tab as well as stab angle adjustment. When I give a pilot a CG calculation, the loadsheet will also give the corresponding stab angle for departure. The balance tabs balance the f...

Indeed. A flattish surface moving through a fluid with an AOA is all you need to generate lift. All the other features are just there in order to improve the lift to drag ratio. :? Nicely put. Flow lines on a drawing or even in a smoke line wind tunnel make it look like the air is being squeezed to...

I'm not in the habit of changing the views of others, but describing my view for you to compare to yours. So let's now look at the air in 2 dimensions: vertical and horizontal. You are describing vertical acceleration as a cause of lift when actually it is a consequence of it. Newtonian physics allo...

"Accelerating air downwards" Whenever explaining lift to people, I try to discern whether their brains are wired to understand a Bernoulli type explanation or a Newtonian one You seem to have a Newtonian brain that is trying to grasp at Bernoulli. To understand lift, we must train the brai...

I'm nowhere up to speed on this, but it all seems to come down to 'did he or didn't he' ? Some cargo pilots have brought up the trim/maintenance issues from a while back regarding the 767, but I haven't seen any further reference. The statements from NTSB do not mention stab or trim changes, just el...

The devil is in the detail

As an analogy: I have an old RC transmitter where I know the functions so well, I can easily use mixing and rates to literally tune an aircraft's performance and control response to fly and feel just the way I prefer, but the 35Mgz frequency was prone to interference and some models were lost. The c...

Of course you understand that the intention was a bullir proof design that matched the flyability and safety record of the 777. The internal arguments between strapping on more complexity in the guise of simplicity vs creating a dedicated airframe must have caused a few fists to come down sharply on...

MCAS - Maneuvering Characteristics Augmentation System Why? When designing the 737MAX, Boeing saw a need and filled it in the cheapest way they could: bigger engines and better avionics on a trusted airframe. A tried and tested way to upgrade an airframe to be competitive and desirable to the airlin...

It's a classic case of creating an unrecoverable problem in the process of fixing one. But obviously not nearly as simple as that. Let's look at this from 2 perspectives: 1. The accountant. They think and operate in the long term interest of the company, oblivous to sentiment and morals, their work ...

Not the best example I could find but watch the section in the middle where they use pulses of smoke in slow mo.

I'll let you absorb that and then try explain to me what you think you are seeing and how that creates lift.

In this case, to function well extended and fit the scale profile when retracted.

Better than explaining Bernoulli/Euler equations or trying to dumb it down for human consumption, I'll try to find a video clip that the brain can digest and explain from there.

I've identified this as the 'i' 'o' of the logo starboard side forward of the engines, so unlikely to be from uncontained engine failure. All punctures are from out to in. The regularly spaced scrapes on the lower left don't match the excavator bucket forks. The top edges of the window frames can be...

What do you make of this panel? Not extracted from the crater due to lack of scorch or mud marks, found within yards of the main wreckage. IMG_2856.JPG Note the puncture marks and spread. Then compare to MH17 I've not seen this on any other aircraft remains. Even PA103 and TWA800 showed out to in fr...
