thus my statement that it's better to wait regardless how long it takes, the truth and the facts will be explained, stop trying to master the topic, you once again  are wrong and you can't admit it, stop the specultion, let the professional s do their job and after you can make you case if you do have a case to make

Wrong? Are you saying the RAT wasn't deployed because MSM haven't picked up on this yet. Have you watch the videos I linked. My guess is you haven't.

  • He's not assuming the RAT was deployed. He's showing it. If you've got nothing worthwhile to say say nothing.

    I'll wait for the report. Because I'm not a pilot. Because I'm not an aviation expert Because I'm not an investigator. Good bye

    Even he's a pilot - leave it to the report which will be filed by official investigators. Anything else I'd just guessing.

Air India plane crash: Asari’s video clue points to equipment-linked emergency, possible power backup deployment; Flight Data Recorder holds key

While aviation experts did speculate whether the APU (Auxiliary Power Unit) or RAT (Ram Air Turbine)—both emergency power sources on the aircraft—were deployed, the clearer video sourced directly from Ansari’s phone seems to suggest that the RAT was down. That ties in with what the sole survivor testified to—a loud bang accompanied by the light going out, and then a green light coming in the cabin. And the captain’s mayday call.

Now, a dual engine failure is the rarest-of-rare event. But if the RAT deployed, it means there was a grave emergency—either a total electrical failure, a debilitating hydraulic failure, or a dual-engine failure, or a combination of these or more factors. Given the appearance of not sufficient lift and loss of thrust, the dual-engine failure theory, which many experts earlier said was not probable but still theoretically possible, could now well be a leading question for investigators to look into.

Slats

 

Slats or flaps. You still can't see them.

As stated not easy to see flaps set at 5 and of course impossible of course to see leading edge slats.

The leading edge slats appeared  to be deployed on a couple of the post crash VDOs I saw.

Se my post above  -  agree about the flaps and VDO quality.

"Mayday" "Thrust not Achieved" "Mayday" Pilot's transmission. Dual engine failure after rotation? Seeming more and more likely. What caused it is now the question.

you really are desperate to make a point with 34 posts so far and yet NONE with plausible reliable evidence, it's just a say so nothing else, you keep mumbling and nothing, rien, nada, niente, zero, zitch trying to make God knows what, give it a rest, enjoy life

I'm simply posting what's happening and what's happening is there's been a huge move away from pilot error or flaps not being set for take off to dual engine failure. Reliable evidence you say. Well there's evidence the flaps were set for takeoff (wreckage), there's evidence the RAT was deployed, the landing gear obviously had not retracted and then there's this from the pilot: "Thrust not achieved… falling… Mayday! Mayday! Mayday!" The question that will be answered by the crash investigation is what caused the dual engine failure IF it turns out that this was the case. 

 

lots of pilots or former pilots making their guesses as to what happened.  I do believe that the black boxes will provide a better and complete explanation of what happened.

Of course and the DVR has been found intact. This, if the video has not been corrupted, may for the 1st time show actual video of an air disaster from the aspect of the plane itself. The fact is though that there's now a high likelihood from what's been seen that there was a dual engine failure. To keep saying wait for the black box investigation although valid ignores what is now being deduced from available evidence. What of course isn't known is why?

Recap the two pilots in video still don't know the cause of the alleged dual engine failure.  Because of the angle of tilt on the landing gear it is alleged the gear selector was in the up position.  At the low altitude and speed the RAT would generate very minimum power.   It is alleged the pilots did their best with full throttle but there was no thrust.

 

We will basically have to wait for fuel test, check if fuel selector switches are intact and what position they are in and many other factors.

 

Tragic incident. Hearts and prayers to families.

Other major factor being electrical or hydraulic or both.

Unsure if this is the flaps in retracted position or possibly above is the extended flap and below aileron...

Sure looks like they've been set for take off.

so it's RAT as you originally claimed  and you are up to 38 posts on the same speculation, well done

like they kept saying, both engines failing is rare but they that area is well known for numerous bird strikes according to the news there.

Bird strikds ruled out. No birds seen there would have to be a lpt of them no bits of birds found and also wpuld have to be a double engine bird strike taking out both engines simultaneously and no smokes of flame out from the engines.

How would you HEAR the RAT from that distance away, over the sound of the engines, if they were both running of course.

The RAT blades are driven by the windmill effect of the forward airspeed. The tips of the blades of the RAT are at or near supersonic speed producing a distinctive high-piched sound at a frequency which can be heard over the drone of the aircraft's engine fans.

Exactly. As heard in the video. Sadly some see fit to comment without educating themselves first even when the information is provided.

First I've heard of all these birds and strikes.

Dual engine failure. Speculation sure but speculation based on available evidence. Flaps set at 5 as it seems from the wreckage. RAT deployed as clearly heard in the video. No audible sound of the jet engines spooling up. Mayday saying "no thrust, falling". No evidence of bird strikes taking out both engines. Undercarriage showing that it possibly started to retract but stopped. None of this is speculative. It's there to see. Only speculation now would be IMHO what took out both engines simultaneously. Some are saying fuel contamination, some saying vapor lock but this is truly the bit no one knows. Total electrical failure would be high up the list and would account for the RAT being deployed and both engines failing.

A qualified commercial airline captain at that and the RAT deploys in the event of a dual engine failure. On the recording of the crash, the Dreamliner sounder like a WW2 Spitfire, which was the sound of the RAT propeller turning.

The RAT was deployed. There is no doubt about this. Electrical failure, hydraulic failure or both leading to both engines shutting down simultaneously or some other reason that both engines would shut down would result in the RAT being automatically deployed.

immediately after the first reports of the crash, the news broadcasts included that fact.  I lived in S. Asia too for a couple of years ante birds, called Kites (not sure of the spelling) were always flying around.  They would even attack people on balconies or on the roof of their bldgs.

Indeed bird strikes were considered very early on. Now ruled out. Reasons I have previously stated. There would have to have been a lot of birds. This wasn't seen. It would have to be a double engine simultaneous strike taking out both engines. There was no smoke, sparks or flames from either engine which is normally seen with bird strikes. Basically the bird strike theory has been ruled out simply by viewing the two available videos.

Like I mentioned earlier, the black box has been found so we should be able to get a better understanding of what occurred versus lots of theories though some possibly valid.

Would the RAT do any good in 10 seconds?
