Basically barely got off the ground then look like its trying to land in this video.

Specualtion that they pulled flaps up instead of gear up and basically didn't have enough lift so it looks like a gentle stall right into a built up area.

Looks to be flaps up, slats/ nose flaps down and gear down which is very odd.

Thats a second phase of flight.

I wonder if he selected gear up which would be an expected movement.

Then his hand came down to the engine run switches and selected off.

Never heard a RAT coming out in real life. They do put them out during an air test sometimes.

I am not commenting on the alarms and indications turning off a functioning engine because I don't know. We get one for OEP (one engine performance) when the N1 goes below 25%.

And Sully said he had never heard the 2 engines failed warning before on the A320 so it's not just me. If a check airman that spends half his time in the simulator hasn't heard it before then a line pilot has even less chance.

Or from what I understand, the PM has his hands on the throttle levers until V1 in case you abort take off then just moved his hands down but not in until they were airborne then operated the switches?

I've seen a picture from the report (Fig 12) which shows the gear switch was in the down position.

I think we're never going to know exactly what happened to any degree of certainty, only probable cause.

Depends some companies including mine it's the captain that has them until V1 who ever is flying.

They were selected up before the engines shut down as the bogies had moved for retraction.

I suspect the final report will have more details.

We don't go near those switches after start until shut down. There is no reason to even as a pen holder.

Air France 447 and other incidents demonstrated that fly-by-wire (or whatever we call it) planes don't always do what the crew command. I don't like anything that removes full authority from the pilot to do what they are trained for, so to respond to unexpected complex situations. In a case like this though, turning off both engine fuel cutoffs at such a critical time should probably not be allowed by the FADEC, assuming it really is FULL AUTHORITY DIGITAL ENGINE CONTROLLER. Maybe that falls under the category of trying to make something fool-proof, of which there is no such thing. I guess you have to expect things to operate within the envelope that they are designed for, not against suicidal pilots (I don't mean to malign the Air India pilot yet, so I'll just stick with the German Wings incident for the case of that argument for now).

I see that is your 9,999th post. Let's see you do that 10K!!
