I'm afraid that is not correct.
The person saying that was the Captain, not the PIC. The captain was resting at the beginning of the trouble. At most, his lack of rest could have impaired his ability when he finally got back to the cockpit.

But, and that's perhaps more important, I don't think the translation is correct, as already posted in the TL thread:

« Cette nuit, j'ai pas assez dormi »
« une heure, c'était pas assez tout ŕ l'heure »

« I didn't sleep enough last night »
« one hour was not enough earlier »

The second part ("one hour") refers to a nap IMO.
The judicial report CVR transcript shows 2" between the 2 sentences, it even write them on 2 separate lines in the transcript.

AZR, thanks for that point.

Across a translation, there is ample room for doubt inhow one understands that remark.

If one's body clock was a bit off, one's rest might be disturbed.
There are other reasons for not getting a full night's sleep, none of which the Captain's remarks refer to. Nor did he amplify. I don't doubt that in his career, he'd flown a flight or two when his sleep had been interrupted the night before. See CONFiture's point ...

If I go to bed to get six or seven hours of sleep, but on a particular evening toss and turn and get interrupted or poor sleep, versus getting uninterrupted sleep, will I just throw up my hands and not make my take off time?

I doubt it.

Whether or not the Captain was alert, or if he was shaking off the effects of a tired body remains a point of speculation. I don't think we can ever know, unless someone comes up with credible evidence. Sharp or not so sharp, he entered the problem playing a game of catch up. There was a finite window of time where remedy was going to be possible, and in that amount of time he was unable to unravel the knot. The two already in the seats put him in an extremely diffucult position. Not sure how many other captains would have saved it, and others not.

We can speculate all we like, we still won't know.

This isn't a TV script, this is real life. Sometimes even hindsight is partially obscured by clouds.

Rapoport's so called report is total bunk. The crew did not complete the Unreliable Airspeed Dril which is a memory item and instructs the crew to turn off the A/P, F/D and A/T. I wont waste my time with the other nonsense.
People who do not have an ATPL and who do not fly the Airbus should keep their petty thoughts to themselves.

Hi

« I didn't sleep enough last night »
« one hour was not enough earlier »

The second part ("one hour") refers to a nap IMO.
The judicial report CVR transcript shows 2" between the 2 sentences, it even write them on 2 separate lines in the transcript.
Thank you for having specified this.
A nap? why not.
Therefore, beacause both sentences are separated, maybe it is possible to think that « one hour was not enough earlier » made reference to the interval of time to get ready (eyes wide open) between the alarm clock ring and the shuttle departure?

We can speculate all we like, we still won't know.

Latest system enhancement to the BUSS is that FPV is available when BUSS is active.
Well what do you know, an IR FPV...

To echo what CONF said, A33Zab's posts are very informative, as usual.

This isn't a TV script, this is real life.
Otherwise you would look for the pilot in the hotel lobby wearing sunglasses and whistling '...ain't feelin' too good myself'.

Grrr

They won't show it to me because of my location (The United States of Bloody America).

I concur, not available to Americans because Airbus, Air France and the pitot tube manufacturers have decided they are not at fault and Americans will dispute it. I am sure it is a totally unbiased report, don't you?

Since we can't see it here in the US my guess is they threw the crew under the bus and blamed them for not following UAS procedures. Is this true?

Well, heck, there are plenty of licensing reasons why we often can't watch content from other countries (am I right, Canada?), and MSNBC has undergone a lot of contractual changes recently, with NBC divorcing from Micro$oft. So, I really doubt that it's a content issue.

At least one version of that "60 Minutes: Australia" 447 video is on youtube - watchable in the USA.

It'll be a Copyright issue!

I'm sure that Channel 9 Australia have plans to sell to other networks, so why not protect distribution on the web.

All 3 parts are viewable via the web in Australia and New Zealand.

The short excerpt (above) seems to be relatively even-handed, no?

The video is not available at the moment, don't know why.
Flight 447: The air safety investigation

I watched it live in Sydney on the free to air 9 network last night.
It was pretty useless. Nothing new at all. Don't loose any sleep over it.

So did I and I was awake half the night wondering why the PF chose to pull back on the side stick after the AP disconnected and apparently kept the back pressure on the side stick pretty much all the way down to the point of no recovery.

It also brought home to me that in the middle of the pitch black night in the middle of nowhere you are absolutely reliant on your instruments, and why did none of them notice the pitch-up attitude on the AH and do what any student air cadet glider pilot should have done instinctively, i.e. lower the nose?

The fact neither pilot could see the other pilot's sidestick position is also a huge concern. I won't revisit the customary "wouldn't happen on a non FBW brand of aircraft" discussion but it would perhaps have helped had PNF been able to discern the PF stick input.

Maybe PF was too occupied fighting the roll oscillation to notice what he was doing with the pitch?

Until you are sitting in the seat under identical conditions, you do not know how well you would have handled the sensory overload. There are load shedding strategies for handling sensory overload, but they need to be trained and developed.

Has training improved that much in the intervening almost 4 years that everyone feels they could handle that scenario should it happen to them?

For those who cant see the You Tube, try installing hola.org which should by pass content restrictions. I saw the 60 Minutes and they crucified the PF but there was little mention of Airbus design issues. Just a brief mention that the other 2 pilots couldnt see PF side stick movements and the stall warning eventually stopped when attitude became unbelievable. No mention of the THS being on or close to its backstop position or lack of AoA instrumentation.

And guess what was causing the roll , the PF, so why not just pull up because the airbus can't stall in normal law so that is why you don't need experienced pilots to fly an airbus. Only this time it slipped into a law that had no stall protection so everybody died. This is the future so get used to it. Hopefully it won't reach the USA.
