1. Yes. Flap 45 is the normal landing config.

2. I don't remember any special limitations.

3. So no.

4. Of course.

5. Other alternative landing config is Flap 22. Only used in LV Ops.

Captain not acting in accordance with his job description. Nuff said.

As surprising as it may sound, I agree with you … at least in part … actually the first 2 parts!

It seems to me that the regulatory authorities around the world all pretty much insist that a pilot fly the airplane the way the manufacturer’s procedures describe … and, at least in the US, the Flight Operations Evaluation Board and the Flight Standardization Board evaluates the manufacturer’s procedures to see if any adjustments might be necessary – this includes approaches and landings. This being the case, what kind of effect do you think this circumstance will or should have on the FAA, as you describe in the 3rd part of your justification for this being a good event?

It would appear - as I see it - that there was no vilolation of SOP or limitations.

In the adsence of an atmospheric issue (Windshear, thermal, etc) , it seems that this can be chaulked up to an "Ooops" on the crews behalf.

I'll wait over here while the jury deliberates.

ps: Can I assume that the LV ops requirement of flaps 22 is to satisfy go-around climb performance?

Good question and please bear in mind that I am SLF so am probably speaking through my hat!

Having heard a lot about the laissez-faire attitude of many CAAs [a French noun meaning a policy of non-interference, especially abstention by governments from interfering in the workings of the free market] I wondered if the FAA might be shocked into trying to implement their own rules more strongly. If air crew, ATC and others involved, felt that someone was going to kick their backside - then rules might be followed.

I realise, of course, that the chances of this happening are effectively zero. I know that CAAs around the world have not got the money and people to even begin to hold the tiger by the tail. In this specific case, I hope that all the staff of the carrier will have got a very nasty shock and that the crew will be made an exhibition. The FAA ought to be jumping on them to see why their Cpt failed and what other procedures of theirs might be failing. They won't of course and I know that this ideal is from an old fashioned world!

So, apart from my wishful thinking about the FAA, this carrier is luckier than they deserve and all their pax can travel in the knowledge that this carrier is now SAFER than it was before.

Truthfully I'm not 100% sure why it was flap 22 for the CAT II landings, but yes, G/A perf must have been a part of it. Flap 45 just added a lot of drag.

While these guys didn't breach a SOP with their very high bodyangle on touchdown, that is not really the point.

There is no SOP, for example, that says you mustn't land upside down either.

Daft New Year's Question....

Should we still call the 145 a Barbie Jet, now that Ken is flying the big'un?

Actually it depends on the operator, as stated previously:

My company now states Flap 22 as the preferred landing configuration in all conditions, not just LVPs, by which I think you mean a CAT II approach. Flap 45 reserved for those who have not yet been trained in Flap 22 / don't like it / performance limiting...etc

Well, I wouldn’t be so sure of that outcome. While I’m sure to many observers it seems like the National Aviation Authority (NAA) for a particular country either does too much or not enough on any given situation … probably the curse of all regulators. But here, I think I’m on fairly solid ground saying that the regulator in any state would look at this type of occurrence as something that warrants additional scrutiny. As this occurred in the US, this incident (perhaps “accident” depending on the dollar value of any damage) will likely have the FAA focusing a lot of interest in not only the training background of the pilots involved (notice the plural) but on their respective operating backgrounds as well. Additionally, I would be quite surprised to learn that there was not a review of what that specific airline trains their pilots regarding flare and flare attitude and what, if anything, these pilots are told regarding any differences with less or more flaps during final through the flare and touchdown. Additionally, I wouldn’t be at all surprised to learn there was an “informal” discussion encouraged between the assigned Principal Operations Inspector (POI) and each respective US certificated airline regarding the same training issues. The FAA Flight Standards personnel are mostly pretty competent chaps who know that an airplane lands most safely and surely from a level flight attitude – which, while varying from airplane to airplane, almost never exceeds 4 to 6 degrees of positive pitch attitude for any airplane. I certainly wouldn’t want to be the next US airline training manager to have a pilot flare an airplane to 13 degrees of pitch attitude (17 degrees AoA) and then allow the airplane to settle on its tail!

Quite an excellent point, I do agree.

Well, all the planes I have flown so far came with books mentioning the landing technique. It also contaied a graph showing bank and pitch limitations and the combination thereof...

I would very much take this one as a nonadherence to SOP - I forget the official classification, wether it was H1 or H2 or whatever, but the definition said something like "intentional breach of SOPs".

Bit harsh to hang the guy because of a couple of sentences in written form, especially not knowing the context in which it was said.

If Flap45 landings are normal then it appears to me this FO might be guilty of no more than a bad landing. Not everyone's a test pilot. Seems like he flared high, then held it off trying to make a good landing instead of putting it down regardless.

"Seems" - from what's written there. Maybe you are in possession of more facts? Or did I miss something?
Well, some here don’t believe it’s too harsh to acknowledge what happened. What happened was that the aircraft landed and then struck the tail … or … it landed on its tail (the facts will be obtained after reading the FDR), and there was substantial damage to the aircraft … to the extent that the NTSB has classified this as an aircraft accident rather than an aircraft incident.

The F/O was operating the aircraft … of that there is little doubt. The Captain is in charge of what goes on in his aircraft … of that there is little doubt as well. According to the information available, the F/O made the incredible statement to the NTSB, that he briefed on the fact that his landing technique was not in accordance with standard procedures. That isn’t speculation – that is what the F/O said. On that basis alone, the questions being asked are the basic questions that should be asked at some point - at least in my opinion. 1) Why did the Captain not question the F/O as to what it was he was describing that was considered “non-standard” before allowing him to fly the landing approach? 2) Why did the F/O think it was acceptable to hold the aircraft off the runway until the stick shaker sounded? 3) Why did the Captain not take the aircraft away from the F/O at the first sign that he was raising the nose beyond that which is necessary to safely land the airplane?

YoDawg, all the information available to me is what I posted from the Herald at the start of the thread. Of course I don't know everything and can only judge from these few lines.
You might feel this is inappropriate, and you may be right. But then we couldn't discuss anything on here.
I did ask, and am doing it again at this point, for anyone who knows more of this incident to share the information, I am highly interessted.

I do uphold my opinion though, this kind of announced "I'll show you something" is not acceptable and had demanded oposition from the other side of the cockpit, no matter who says sucha thing.
My company pays me to fly safe, safe and also safe, and if I have some time left over, they are happy to see me be on time and give the passengers a comfortable ride!

Final Report

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The flying pilot's excessive angle of attack during the landing flare resulting in abnormal runway contact.
from: DFW08CA215

Flap 22 for CAT II is so that in the few seconds after becoming visual at 100' the change into attitude for touchdown or flare is less and if you are on speed you can pretty much fly to the runway as it is. Also, helps with less sink on flap retraction in the go-around.
