Yes. But the level of information also is (unfortunately) often laced with misinformation, it being the year 2025.

That's good advice.

This is a common complaint here at PPRuNe, has been since it began. (And I empathize with your position).
One of the best things that our Professional and Knowledgeable members can to is point out errors (or nonsense) as it is encountered, or report posts that are well beyond the pale.
The Mod/Admin team has already engaged in substantial clean up.

General point:

It is not uncommon that on social media, and in the press, we see sciolists pop up when a plane crash occurs.
What is a sciolist?
A person who pretends to be knowledgeable and well informed.
We used to have a warning about that stickied on a few of our forums.

Please, for all of our readers, keep that in mind as you try to separate the wheat from the chaff during this discussion.

Would any of our 787 qualified pilots care to comment on this as it relates, or doesn't relate, to the aircraft's brief flight shown on the CCTV video?

Thanks to @tdracer for the informed speculation.

The flight from today is in red with a larger marker. As you can see, it appears to be in the same position in space as every other flight this week at the same point in time (with all the caveats above). It did, however, have a ground speed approx. 10knts less than any other flight this week. Is that significant? I don't know. It certainly isn't airspeed anyway, so may not mean much.
I will suggest that you relabel your red pin as 12th June rather than 12th July.
(Interesting picture that you painted, in comparing to similar events using a similar data baseline).

Loss of lift. VNAV engages at 400 ft and targets airspeed in MCP.

PPRuNe, mate, and that gating has long since ended - since about when Danny sold the site.
I empathize with your frustration, and you have no idea how much has already been scrubbed.
There are some wise engineers, ATC pros, and GE/RR experts who are not pilots but who do post here, and whom we'll not bar from discussion.
Do you understand why?
(Yes, we also have examples of Sturgeon's Law in action as well).

The junk-posters would be wise (though when hell freezes over) to recall that the people who care the most about getting the right answers through the investigation are the . . . . professional pilots.
I got the reference and laughed, because I read that book.
The PPs prefer radio comms that are more signal than noise, so of course objections will be raised when the noise level increases.

I have discussed this with some of the mod and admin team.
For the time being such speculation isn't just premature, it is potentially slanderous to our colleagues who died in this crash.

I understand why some wish to air that inference. Please show our deceased colleagues your ability to exercise patience.

If evidence of such comes to light then obviously the state of play changes.

If you compare this crash to the one recently in China (that a few of you have referred to), in that case there was a flight path trajectory that really stood out. In this case, there is no such flight path trajectory that leaps out at you as being wildly out of the norm. The apparent loss of power in this case, that has been discussed at great length, has been shown to have a variety of possible initiating causes or event chains. In time other information may come to light that reveals an as- yet-unguessed anomaly that none of the brain trust of PPRuNe has come up with.


Again , inference is not evidence.
Then there's the other advice I am often given:
It is usually best not to attribute to malice that which can be attributed to simple error.

Thank you all in advance.
Let's keep it professional.

Reading a few posts about an APU-to-pack takeoff, or a packs off takeoff on a 787, because of the hot weather, makes me shake my head.
There is no bleed air on the 787. A packs off takeoff, or an apu to pack takeoff, is never done. There isn’t a procedure in the fcom to describe it. It is also pointless. The packs are electrical.

BOTH engines are reported to have shut down, so whatever happened is a system common to both engines.
Presumed or reported? If the latter, by whom?
I do not intend to single you out, but I want to illustrate something with this response.

A lot of discussion on this thread has pointed toward two engines failing - or losing power - for a variety of reasons.
PPRuNe members are analysing and discussing this tragedy.
When a credible report comes out that says
"Based on FDR data, the two donks quit at {such and such a time} and {x event} associated with this indicates that they {failed or shut down} by time {XX:XX:XX}"
you, or we, can say that engines were shut down or failed.

Using unconfirmed news reports, social media, or PPruNe analysis as a basis of "fact" is hazardous.
A number of posters succumbed to this: see the obsession over white and green lights at the exit door (near seat 11A) as but one example.

As an aside: your EFATO story might be of interest on the Mil Av forum.

In that poster's defense, you will find that they joined PPRuNe in 2002, and their original profile entry was 767.
The upgrade to 777 between then and now is within reason.
Beyond that.


With that lighthearted diversion completed, back to the bickering.

(I raise this point based on what's in the profile).
Would that change your desire to engage in a bit of eye gouging of over that particuar detail?

Full disclosure: most of the posts you have offered in this long and painful thread have hit the "makes sense" threshold with me.

But you and I have not read the same thread.
I have had to read all of it.
You've only been exposed to some of it.

I am about out of patience with the mutual eye gouging bit (most of which has been scrubbed) but at the moment thread closure isn't in the offing.
SP closed it when it had run amok.
If it does so again, it will be doubtless be closed for a breather.
That's for the Mod/Admin team to assess.

I feel a lot of love in this room.

Two things that it is hard to get information about, but that aviation industry professionals all have concerns about as expressed in the previous thread:
1. Unscheduled Maintenance
2. Scheduled Maintenance

(1) Based on a passenger's comments on line, a variety of things - passenger side - weren't working as expected. How many other things that "needed attention" could be worked on in the interval between arrival from the previous flight and the takeoff that ended up in the tragic crash?

(2) Based on some discussions by our posters of some known issues with software that have a time tag on them, interest has been displayed in whether or not those ADs and "known issues" had been taken care of by Air India.

Good questions, for the investigators, but hard to answer on PPRuNe at this point since there has probably been a hard lock down by Air India on their maintenance records. They have an investigation ongoing.

The kind of information that people were/are asking about may or may not be leaked. In some previous accidents there have been some cases of that info coming to light outside of official protocols.

But expecting that may be a step too far.

I am sure that the investigators will ask those kinds of questions, and if we are patient those kinds of questions will eventually be answered.

Thank you all for your continued interest. Let's keep it Professional.

Any further splitting of hairs as regards the words of the sole survivor will be viewed with disfavor.
That horse is long dead, and is now top quality industrial adhesive.
Please refer further queries to the above post. ( And the one further up with a best effort translation by appruser ).

I agree. You'll note that I left the quoted post being objected to in the answering post; people can still take a look at the speculation therein.
How many of us, over the years, have seen a case of 'fast hands', and had to catch it, or correct it before things went pear shaped?
In jet aircraft how many systems related dual engine flameouts have occurred at low altitude ? Excluding FOD — birds and ice (which presumably aren’t a factor here) how many systems caused dual engine flameouts have occurred ?

As opposed to how many engine failures, thrust losses, or shutdowns have been caused by crew members grabbing at improper levers under stress or setting wrong data (I’ll include Air Florida in that).

Not meant to be self - indicting by any means but if one is looking at probabilities and far-fetched scenarios you can’t exclude crew actions as a part of that .
I don't think anyone intends to do that.
I felt that the (valid) objection was to the problem of stating as a fact that which is an estimate or a guess.

I checked the official site and found nothing. I went to his link and got a 404 result.
