Thoughts on the Boeing tragedies. technically.

This is false.
ACM has never been aerobatics (or vice versa) although each may include elements of the other.

There isn't one.

im not up on aeronautic engineering
i think there is likely something wrong with boeing.

the fact the usa didnt ground the planes is telling.

it is almost unheard of to have mixed grounding messages around the world.

No, Boeing is a really great company, but flight. even space flight has to be done right before you take of.
Some planes are uncontrollable, no matter what you do, the two tragedies were caused by loss of control, these pilots did not want to die ( some of them do,of course, sadly). so: was it a control issue, an aerodynamic issue? sad, that flying has to become scary again.

my comment may be confusing
i am not saying Boeing is a bad company.

 

Yes, it is a great company , but flying over bad terrain. close to the equator. The tragedies have that in common too.
Flying further North, Canada's WestJet, having nothing but 737s of various vintages in their fleet, will keep flying them.
PS. It can not have anything to do with temperature, even over the equator, airliners operate at - 50 Celsius. chilled intake air.

i read somewhere they are going to make false read/error sensors compulsory in all the models now.

i have heard from very well informed technical people that air current anomalies can take place which can cause big issues.
they are very rare but if in the right place at the precise moment they have the potential to slam the aircraft back on the ground on its early take off or under heavy lift early take off.
if one of these rare weather events happens in exactly the right place at precisely the right moment there is almost nothing the pilots can do.

statistically i guess they are more likely to get hit by bird strike

and it doesn't really matter what type of plane it is in such an occurrence except maybe for some super powerful jet fighter taking off at full-power or something similar where the thrust to weight ratio is massive.

 

Even then, for example, an Air France Airbus over the Atlantic, the equator, between Brazil and Paris, crashed, because the outside sensors had been taped over for maintenance and covers not taken off before take-of.
nobody, crew or computer knew what was happening out there with the air flow, fed wrong readings.

 

Another theory has emerged why the pilots were not able, even after shutting down the auto pilots to wrestle the nose up enough to avoid disaster is. that:
The aerodynamic forces in the dives where such, that the operating systems on the elevators could not overcome the load, called "blowback" ?

 

having no previous comprehension of this science i am googling and gradually trying to grasp the nature of the science being discussed.

what i have is an intuitive feeling of fly-by-wire margins being too small removing any recovery margin for such events.

 

Same in my case, having "seat of the pants " levitating, "eye ball engineering" experience only. In an experiment, you change one one item at a time only. and here with the Max, aerodynamics and control were both new.

 

Here is a puzzling comment from an article in the Guardian:
New engines

"The LEAP engines are designed for greater range and efficiency - but are heavier and need to be fixed further forward on the wing" as written by Gwyn Topham.
If they are heavier than the previous ones, , and in front of the wing, The center of lift, being in the 1/3 of the chord. would a heavier engine not have to be installed closer, back toward the cg?
It could not be a Boeing error, but a Guardian writer's. or m mine?

 

Quoted from New Scientist article March 25,:"- A part recovered from the Ethiopian Airlines flight indicated that the jet’s horizontal tail was in an unusual position, pointing to MCAS as a possible cause -" It does not say which the unusual position was. elevator up or down. If it was still was pushing the plane down into a dive, with sufficient heights, the p;ane would have reached inverted flight like the Alaska Air flight 261 DC9, which had a stuck elevator too, but because of lubrication problems.
It was the planes that failed their pilots.
It points to a similar cause as Air France Airbus flight 447, in 2009. where stall sensors were sending wrong signal, they had been covered. Sharp eyed old fashioned captain's walk-around pre-flight might have helped to discover it.
It might not been a faulty external sensors. pitot tubes, but the computer, the software.

 

Feds said it would take 1.3 billion dollars for Nasa to have the expertise to do all the due diligence that corporations provide. understandably.
How would you train examiners to do that. this is not checking the cables on a home build, flying to Oshkosh.

 

could nasa license their personal choice of people from all airline producers to act as independent evaluators at a profitable price to all air lines ?
sure they could.

The profit they make could go into a fund to pay for complicated air accident investigations globally as an independent learning institution that publicly publishes its findings.
Global analysis and advice for better aviation safety etc etc...

there are plenty of ways it can work.

 

good point. Deep expertise in all of this is rare, and it has to be used to do the work, but then also to critique, find flaws, a potential conflict of interest for industry workers.

 

if nasa could simply pick the staff from the private companys and then allow the staff to privately contract back to the companys for assigned specialist work.

however...
the alt-right & (usa liberals & liberal conservatives)conservatives would see this government group of intellectuals as a threat to their egos so would seek to destroy them. as they always do to intellectuals. The Republican party would be constantly attacking them and trying to destroy them.

 

well, reminds me of R Reagan firing all the striking air traffic controllers.
Read on another news service that the anti stall feature kicked in automatically, beyond the pilot's control.
makes you even scared to get into our self driving, driver monitoring cars of the future. Older used models will be in high demand by freedom lovers.

 

auto crash kicked in

"Reagan " was an actor
note all the hate from the republican party towards Hollywood and actors.

evenly & constantly distributed fear paranoia and hate distributed by the republican party...

self driving 2nd amendment cars lol
self driving patriot act of the 2nd amendment lol

"you appear to be a minority which is currently outside the required costing for government enforced private compulsory insurance, please step out of the drivers seat and let a rich white person drive, or insert your credit card & remain inside the vehicle while the doors are locked"

rich republican party members with paid up fees paying live pay-per-mile who go where they are told to go as tourists.

 

we are talking Boeing here, Seattle, Microsoft, Starbucks, nuclear submarine base.
