Software/firmware bug or common-mode hardware failure? Hard to tell without more information.

This just makes me want to puke. Too many opportunities to puke nowadays. This administration makes patriots effectively bulimics. Itâs gotten to the point that one has to ask âwho hasnât tried to buy influence?â
Thatâs why I was wondering why Trump said something about this. I stopped wondering, after I remembered Joshâs âTrump razorâ rule.
Well duh. Those things are just so darn complicated. Who knew?
Are you sure that his name isnât Dennis Boeing?
I know nothing but it sounds like a software issue. Trump in his clumsy politicking may have accidentally hit on something. Also I always wonder how much of this aircraft software is hackable by the black hats.
If it is a purely software-related issue, Boeing (and maybe the airlines) should have some sort of training/testing simulator that they can run it through to investigate. Though it obviously doesnât happen every time or more pilots would have noticed by now.
Yeah the speculation is all very premature, with so many factors involved. The new engines on the 737-MAX did force Boeing to move the wing to the rear to preserve the center of gravity, which in turn contributes to a tendency for the aircraft to pitch up in certain extreme flight regimes (and in turn led to the features like MACS intended to push the nose down again, if pilots didnât realize this was happening). Still, all anyone can definitively say is the MAXâs flight characteristics arenât quite like other 737âs, and that the pilots of both flights complained about keeping pitch on the fatal flights, or flight immediately prior. I canât blame aviation authorities for temporarily grounding the aircraft given that fact alone.
That said, for Boeingâs sake I do hope the two crashes are unrelated bad-luck or bad-maintenance situations, because it does seem like a pretty big coincidence otherwise.
It could take a year to get this sorted out and it might be a random thing in the end, or it might in fact be some sort of engineering problem. Nobody knowledgeable would want to do much guessing at this point. As always, Trump is a moron, and complicatedness is not the problem here. Modern engineering makes stuff much, much safer.
The rest of the world cares about itâs citizens, America, under trump, only gives a shit about the stock market and Boeingâs stock health. If a plane falls out of the sky, it is because if is fucking complicated. Capitalism is failing folks, and we are watching its death throes.
If the Boeing CEO lobbied Trump on this issue, we can rest assured his lobbying would be totally devoid of any complicated facts 'n stuff. Probably more like âMr. Trump, the Chinese and the French are trying to play you, and steal American jobs! If only someone was manly and strong enough to stand up to themâ (in my minds eye I can see Trump grabbing his lapels and puffing out his chest at that point⌠heâs so easy to play)
WellâŚthe 757 anywayâŚ

While not every design flaw -if itâs even that -can be caught in the testing phase, it seems to me, as a non-expert, that more diligence was necessary prior to allowing sales of a relatively new type of aircraft on a large scale. Itâs mind-boggling to me that even the pilots were caught off-guard regarding some of the attributes of this particular aircraft.
Much of the world has grounded these planes, at least for now, while we havenât. I fervently hope that the reasons we havenât are for the right reasons, but knowing Trump, I canât assume anything.
They do an incredible amount of testing and simulation when developing a new aircraft, but they canât be exhaustive. In addition, weight&balance calculations for aircraft are based in part on assumptions about the mass of passengers and baggage (afaik freight gets weighed and positioned exactly). The procedures for estimation have gotten better, but if you have a new aircraft where the center of gravity is already a bit hinky, itâs possible that the effects of any errors in calculating exact CG might be magnified in unanticipated ways.
No thanks
MCAS kicks in apparently only after the flaps are retracted - so about 1000-3000 ft above ground level. Thatâs somewhat reassuring since this problem wonât therefore happen too close to the ground and now every pilot knows you gotta turn off the electrical power to the stabilizer servos pronto if this happens. So it makes sense then that they arenât grounding them yet without more information. There is a quick way to defeat it.
That said, I wouldnât want to fly on one till the âblack-boxâ information is reviewed to determine what happened in Ethiopia. Some reports have the plane in flames or smoking as it went down which doesnât sound like a wayward stabilizer at all.
Somewhere in the code, thereâs a âfloatâ thatâs defined as a âdouble,â instead.
I do software development in my dotage, to keep myself off the streets. The well-known First Rule of Software: âThereâs always one more bug.â
