Boeing down in India

Yes there is a back up power source.

But the guy is full of shit, the Spar valves aren't spring operated, they are motor operated.
If they were spring operated they wouldn't need backup power supply.

8:22 of the video, this guy is making claims based on 2nd hand knowledge and Googles AI search.
The automatic shutting off of fuel supply during power failure is obviously stupid and Boeing does not design the system to do that.

The 787 is a wonder of electrictricky and software, there was a tonne of issues with software when it first came out, there would be new software to load almost everyday for the first year or so of service. Many of the new electrical things that used to be Bleed air powered have proven to be less reliable than Bleed systems, and much of the electical system can, and does give grief.

BUT, the FADEC/EECs on the engines are old technology that has been around since the 80s, simple stuff like fuel systems, spar valves, heat exchangers, hydraulic pumps, electrical generators, etc are all just updates on older technology. In many cases new cars have far more electrical wizardry that a 787 does.

Most of these video on YouTube are by completely clueless people usign 2nd hand information, or a Pilot who has read the FCOM and spoken to some engineer/mechanic (who himself probably can't remember exactly how the system works from their training 10 years ago).
I've not watched much of Stig Aviations videos, but from what I have watched he has made some errors in the information he has given, so even there none of the info on YouTube is 100% accurate.
There’s this one guy on Instagram who only flies Microsoft flight simulator, putting videos out on this shit. He doesn’t even have a pilots license and he admits it but he’s commenting on this stuff. It’s wild

I think every forum I have been on for a length of time I found a poser wannabe typing from mommies basement

I had thought about doing some sort of YouTube thing around aircraft engineering in the past but decided against it for a few reasons:

A, it's a clear breach of my works social media policy
B, I'd have to interact regularly with the weirdest spotters
C, People at work will think I'm a looser
D, I'll think I'm a looser
E, I just want to do my job and go home

I guess there would be some benefit to people who genuinely know what they are talking about giving out info, but I'd just be downed out by the click bait types.

Just not worth the effort.

There’s plenty of people out there doing it and there’s a couple that are actually fairly decent and then there’s the other that are just trying to capitalize on the attention. We’ve got a bunch of my airline and we just fucking rag on them all the time.
 
Just saw a quick blurb on some youtube and the last transmission that went out was something to the effect the "we are not making takeoff power" or something like that.

Makes me wonder it they chose the wrong de-rate and maybe the wrong flex temp?
As in selecting TO2 instead of TO and maybe it was a TOGA but they used local temp as FLEX temp.
Just a random thought.

When in doubt go to TOGA

Flex temp.

Does that limit power based off EGT?
 
Can actually increase thrust in some cases.. I’m old enough to have 750 hours on the KC-135A with water injection for takeoff! LoL
Water injection is the earliest form of nitrous oxide. It dates back to WWII, the Germans were testing it in their fighter planes during the war. Water being misted into the air intake in a controlled amount just takes up space since water is not compressible it simply increases the compression ratio in combustion chamber. On a gas engine extra fuel has to be injected along with it or you get a very lean condition quickly. Water that enters an engine that is mixed with the fuel is dangerous because the amount it not controlled. and can cause the same high compression conditions and engine failure if it gets to a hydraulic lock condition in the combustion chamber. The turbine engines can ingest an insane amount of water before it causes an issue. Internal combustion gas or diesel not so much.

The other part of water injection is it cools the combustion chamber to reduce pre-ignition and detonation. You can then advance the timing.
 
FW-190's and I believe a few other airframes where modified with N02. It was to get up to altitude so they could intercept the bombers in the thin air. Because their compressors could no longer keep up.

The whole move towards WM injection in war birds was because they didn't want the added drag of larger inter/aftercoolers.

Also WM can be injected in multiple different areas, each one doing something a little different. Pre, Post compressor or direct injection.
 
Improper flex/derate could explain what appeared to be rotation at the very end of the runway, given the massive cloud of dust immediately after lift off.

We had a couple airplanes almost not clear the fence at a certain well known short runway airport. They never got to commanded/requested takeoff thrust. It wasnt a systems issue(the airplane data was correct), it was a dumb chimp at the controls issue combined with our dumb ass auto-throttle takeoff procedure that doesnt comply with the Boeing FCTM. We keep having issues with people not getting to the programmed N1 and they always blame the auto throttles. Ive brought up numerous times if we changed our stupid ass procedure to mirror the Boeing way it would solve like 99% of our issues. I wont say 100% because I will be proven wrong, but in 10 years of "set takeoff power" and using Boeings method, guess what, ive never NOT hit the requested/commanded N1... never. Well one time when one of the auto throttles didnt move when I hit TOGA, but that was a broke autothrottle issue.

Burbank is a bitch.

Makes me wonder if the crew failed to set the power before 80kts and when the auto-throttles go into HOLD mode.

no clue... as you know in the airline industry you never get the whole story. you just get a reminder to "adhere to policy/procedure" and then a blurb of what said policy/procedure is. I have questioned our procedures team on this and received a grand total of nothing back.
 
Some more outstanding commentary.

Despite being completely wrong before, "where there's smoke, there's fire" so it must be a software glitch.
Just ignore the fact the smoke wasn't actually real, and the small pieces of evidence he has doesn't really prove anything other than software/complex systems have had issues in the past.

 
Which really makes you wonder why no preliminary statement on what happened from either party......
Probably because the only people that care about it are YouTubers and armchair experts.

Airlines and people who need to know will have already been told if there is anything to be done, or the FAA/EASA/Other CAA will have released emergency ADs if it were necessary.

Has anyone mentioned that Boeing and Air India have real time data and already know what systems and equipment were activated or disabled
No, because the people commenting on this issue don't actually know anything.

Airlines get sent alerts from Boeing/Airbus/GE/PW/etc all the time if they notice an issue in service.

Chances are they have a good idea of what's already happened, they just haven't told the content creators yet.
 
Surely the families of the 242 people on board and the 30 or so killed on the ground haven’t forgotten.
Of course not, but what good is preliminary report going to do for them?

They need a huge amount of support, but a statement from Boeing with a few data points that creates a new media fire storm isn't going to help them.

Especially when in all likelihood it was human error or malpractice that was the cause.

Peace of mind to know why.

I personally think the airline missed something, assuming the prior flight the passengers who mentioned an electric issue are legit and it seeming like the rat was out with an obvious lack of thrust. Given that the 787 have been a very good aircraft, I think India Air fucked up some where, maintenance, pilots or a combination of both.

India ain't the US, not sure what kind of control over information they have.

I'm guessing the Indian's asked the NTSB to take the lead. Boeing is a party to the investigation. Boeing cant say shit as a party to the investigation lest they be kicked off the investigation...

So you wont hear a peep from Boeing on this...
