'Damn it, we're going to crash, it can't be true!'

[B17NNS]

AF447 transcript of the CVR released.

http://www.dailymail.co.uk/news/article-2048654/Da...

Marc Dubois (captain): 'Get your wings horizontal.'

David Robert (pilot): 'Level your wings.'

Pierre-Cedric Bonin (pilot): 'That's what I'm trying to do... What the... how is it we are going down like this?'

Robert: 'See what you can do with the commands up there, the primaries and so on…Climb climb, climb, climb.'

Bonin: 'But I have been pulling back on the stick all the way for a while.'

Dubois: 'No, no, no, don't climb.'

Robert: 'Ok give me control, give me control.'

Dubois: 'Watch out you are pulling up.'

Robert: 'Am I?'

Bonin: 'Well you should, we are at 4,000.'

As they approach the water, the on-board computer is heard to announce: 'Sink rate. Pull up, pull up, pull up.'

To which Captain Dubois reacts with the words: 'Go on: pull.'

Bonin: 'We're pulling, pulling, pulling, pulling.'

The crew never discuss the possibility that they are about to crash, instead concentrating on trying to right the plane throughout the final four minutes.

Dubois: 'Ten degrees pitch.'

Robert: 'Go back up!…Go back up!…Go back up!… Go back up!'

Bonin: 'But I’ve been going down at maximum level for a while.'

Dubois: 'No, No, No!… Don’t go up !… No, No!'

Bonin: 'Go down, then!'

Robert: 'Damn it! We’re going to crash. It can’t be true!'

Bonin: 'But what’s happening?!'

The recording stops.

just out of hibernation?

[Ross1988]

Pretty sure I read this a while back.

The main problem was the lack of communication, both verbally and mechanically. As in, when one of the pilots was using his control column to try and control the aircraft, he was pulling back. Which ,from what I have read, is not the correct thing to do. This input was not transferred to the other control column, which the second pilot may of been able to notice and correct.

This is what I have made of it anyway.

Horrible way to go. RIP.

[B17NNS]

Sorry, only just read it.

Yeah them pesky sidesticks got them again

I always find these transcripts chilling - more so the actual audio recording. Particularly Delta 191 for some reason.

Instead of rolling your eyes at me, care to offer an opinion? I did say that, that was my take on it, not gospel.

I'm happy to stand corrected or bow down to a greater knowledge. Was just offering my opinion. The transcripts don't highlight the fact the control columns were independent of each other.

Not sure where you got side sticks from. I'm tired and may not of proof read my post/s correctly.

Airbus side sticks. Operate independently of each other. That little red button serves as an autopilot disconnect and when A/P is off, holding that down give priority control to that side (effectively locking out the other stick).

[Ross1988]

This was what I was alluding too, I just confused control columns with sidesticks.

Thanks for the clarification.

If I recall correctly the key issue (amongst others) was that they never identified that the aircraft had stalled. Sidestick not a factor.

Identifying a stall is pretty basic stuff - likely to be rooted in (probably complicated) training / currency weaknesses..

Big long thread on it here.
Seem to remember the link in the OP being a pretty effective explanation.
And I think it was that thread that mentioned a book called The Naked Pilot - good shout whoever that was.

Well ok, they sum inputs, poor post on my part, thanks for the spot!

There is a diagram of the mechanical side of the sidestick operation/design knocking about, including the dampers and counterweights, I'll see if I can dig it out...

bump!

[HowlerMonkey]

The carriers training only in "zero altitude loss recovery" might be partly to blame.

[Chuck328]

Never seen that one before. i'll take that image and file it with all the other odds and sods that you pick up over the years.

Thanks for that Mo.
