The director of the French Investigation and Analysis Bureau (BEA) just spoke on one French TV – LCI highlighting the mismanagement of pilots following the Pitot tube defects is the main cause of the crash and added that the trainings of pilots were inappropriate to deal with this situation. I react that we as passengers are at risk and training in flight simulator cannot and will not be the same when in the air as in a flight simulator we can reset the system when a pilot fails.

Hmm - lets see the report in full first before we decide to re write the rule book or training manual I say.
In my experience, some people meet and deal with certain challenges or difficulties that most people will never ever come across. It is important that we learn from past events in a positive manner, but it must be measured in a rational way.

My first comment is that I don’t see where you are going with this. I think that it is good that simulators can be reset after a prang. If there were no flight simulators then the death toll would be higher in both passengers, aircrew and those on the ground, when anything from Cessna’s to Airbus 480’s start landing on you head.

Modern simulators have a valuable role to play in both aircrew AND ground maintenance training. The better the processing power of modern computers means more realistic training scenarios. Yes OK granted, in the end the real thing is the best and that cannot be replaced. But simulators are:

1. More cost effective.
2. Can be reset.
3. Environmentally more friendly.
4. Don’t need airspace, take off clearance, air traffic control, diversion airfields, emergency fire cover etc etc.

You are more likely to be killed on the Motorway on the way to the airport than in the flight out from or back to the airport.

Human factors is a big issue in aviation and it is taken very seriously. But, this tread has very little to do with IOSH. This is a health and safety forum, not PPRuNe.

Umm, I was also unclear about where it was heading as well. Human factors has always played a major part in aviation and ST's are a hugely valuable tool for crews and they have been around since the beginning of aviation in some shape or form. Of course one of their greatest assets is that they CAN be reset and the crews CAN learn and try again. The training may have been 'inappropriate' but I find it difficult to believe that he was suggesting the training should have been 'live' rather than 'simulated'! Getting it wrong in the sim seems infinitely better than the alternative! Better to fix the fault of course. PPRuNe might be more appropriate.

Well I had to look it up but now know that it stands for "The Professional Pilots Rumour Network."

I found this link to the French BEA site. If this is the accident referenced then this is useful reading?

http://www.bea.aero/en/e...af.447/flight.af.447.php

Given the accepted high level of competence in the aviation industry, especially in post incident investigations, and that an airplane is a place of work, it must be of interest to an H&S forum?

With 25 years spanner experience on aircraft (be it predominantly military) I agree with P48, there is some cross over’s to health and safety. Human factors (as already discussed), working at height (ground maintenance not flying at 40K feet), deep vein thrombosis, re-cycled breathing air, cosmic radiation……they are all hot topics which have direct or indirect links to health and safety. There are too many to list, but this post is leaning more to a flight safety issue.

Flight safety rules are very strict and basically have a slightly different ethos and culture. You can for example argue that in theory, there is no place in flight safety for the “so far as is reasonably practicable” approach. When flying as a passenger (self loading freight), it makes me laugh when people moan because we are delayed at the airport for “technical reasons.” To me that’s good news; the crew have done their pre-flights and found a problem which will be fixed now, not later.

The post needs to be taken away from flight safety and made health and safety relevant or the mods have the right to lock it.

I think the original poster is missing an important point. Flight simulators can be set to produce situations that one would never risk producing in real life. This allows pilots to experience a situation that they would hopefully never encounter but that, if it should occur, they have the knowledge and experience to deal with. Just imagine simulating a serious failure, e.g. both engines in a twin engined aircraft failing, or a full failure of important flight instruments in bad weather. Would you want this to be done in real flight or on a simulator? And if the pilot does get it wrong the mistake can be analysed so that both trainers/technicians and pilot learn. With a simulator you can try: "I wonder what happens if....?"

Betta, thanks for the clarification. While you were fixing them, I was, amongst other things, supplying the juice to keep them moving :-)
So I too have an understanding of the ethos and environment. Only ever co-piloted one on a simulator and almost managed to junk that within the first five minutes.

I don't, however, agree with you about the relevance. A discussion about how a simulator helps to train pilots is no different than a discussion about how advanced driving and the use of simulators helps drivers to gain without pain is it?
I do agree that the aviation technical detail etc is probably beyond the remit but the use of simulators / simulated exercises is important in many situations.
They are not just used to test or train users but also to test the equipment, machine etc. Their use is essential wherever the consequence of failure is serious of course but also where the human intervention level does not occur until a potentially critical situation develops. It can never guarantee an error free workplace but it is proven to substantially reduce the risk of critical error. Thus it is a fundamental part of training for all such situations.
It is also a constant learning exercise, both technically and for human factors. Each incident brings it's own learning and it is important that those lessons are heard. As a passenger I know that if those lessons are put into place the risk to me decreases, it certainly doesn't increase. If gaining that info from a simulator is possible then better that than an real air accident.
If the official report does make recommendations about simulator training I am confident that they will or have been put into place.

Then I must finish with a little flight story. Sitting on a 747-delay due to tech problems, cargo door will not close properly. 3 hours later, OK folks the engineer has taped it up and put sealant around the seal so we will be able to get you to JoBurg after all. I wonder whether the simulator training included that sort of information to passengers :-)

I think the original post shows a lack of knowledge of pilot training.

Flight simulators are now very realistic - and yes thank goodness you can practice drills, procedures and emergency situations you hope you will never come across in real flying.

If there has been an error in the training system, that may or may not be true. However the purpose of of the accident investigation is not to blame the pilots, but to find the root cause of the accident and make improvements so that the event won't happen again. If it does the pilots are trained in how to deal with the situation.

Aircraft incidents and accidents are investigated to a far greater depth and with greater rigour than you will find in the vast majority of normal industrial accidents

Aviation has a fantastic safety record, for the most part in recent times (considering the numbers who fly etc), but never forget when it does go wrong you don't often get a 2nd chance. Beyond the comfort of your inflight movies - flying remains a totally un human situation, and inherently dangerous.

WHo would have thought, even 100yrs ago, thousands of people would every day cross the Atlantic at heights of 35000ft, and for it rarely to go wrong.

Pete. I agree what you are saying but the thread (including your post, which I totally agree with fully), is leaning more towards flight safety and not health and safety.

Harsh, Judex.

A quadruplex redundant fly-by wire aircraft enters an attitude outwith the permitted flight envelope in dubious weather conditions presumably due to failure in the AoA pitot tube or related system (with a lack of redundancy perhaps?). Cabin crew have no AoA readout in the cockpit to read and react to ( a key recommendation in the Report).
Why would you suggest pilot error?

Ron,
As it seem a third interim report, the director polarised the attention of pilots errors which I disagreed totally. I missed completely in the title the interoggation mark after Human failures. Sorry. They(pilots) got a few minutes to analyse what was going wrong under stress conditions knowing that they have no right to fail and I just again watched on tv that there was a great panic in the cockpit as they could not rely on data that for me a trained pilots will never faced this level of stress / panic in a flight simulator knowing they can reset.

You are right in the sense that any simulator is just that 'a simulator' and will never recreate real life 100%.

So do you recommend that pilots practice a twin engine failure in a B737, while enroute to Malaga with 200 people on board....... no thought not

Not really sure what your point is.

Human factors is a big issue in aviation, nuclear and oil & gas sector - I've have some reasonable experience of it from the design point of view.

So what do I know - ex aircraft engineer, so very familar with aircraft operations, maintenance etc Also had a go in a simulator, they are very realistic. Never did manage to land a VC10 in one piece.

I did fly one between Didcot Power Station cooling towers, but thats another story

Experts need to think outside the box on the way to design or review certain aspect for a suitable training for pilots. May be this exists already but not being an expert in this domaine, last night I was thinking of what can be done such as how to assess the human behaviour in stress or panic situation. Psychologists or aviation companies need to do something to avoid recurrence thus drawing lessons from this accident and others. By the way another airplane had an accident in Ghana yesterday and god blesses no victim.

Once again, I'm really not sure what the purpose of this post is/was.

Human Factors is taken very seriously in aviation both by designers and, operations, psychologists etc.

I'm sure if there is anything to be learned about the human factors side of this accident or indeed any other aircraft accident whether of a general nature or specifically about the operation of a particular type of aircraft (including ATC etc) then I'm sure it will come out in due course.

Maybe you should write about your concerns and expertise to the Civil Aviation Authority, I'm sure they would be interested to hear them.

Eiher that, or this was a 'troll' posting - if it was, it isn't a very good one.
