This team should redesign and correct the FCS for AIRBUS with all the dangerous garbage addenda. (please no graceful degradation only direct informations).
Seems that somehow the idea that being able to tell the difference between communications system and flight controls is overrated crawled into this discussion. It is important to tell the difference if you are seriously into aviation.

I think someone has no idea that pilots learn physics of flight before they are let anywhere near any aeroplane, that they have to be quite versed in it before starting their type rating and what is written in the preface of every Airbus FCOM. Thanks for entertainment, though.

Where? Only in the mind of some fairly clueless PPRuNers. Airliners are fully stalled during flight testing, which doesn't imply they are tested to 45° AoA. Just nice aerodynamic stall and prompt recovery. Those that got recovered only through use of anti-spin chutes, got stick-pushers. Simples.

What traps? Is there something you don't like about Airbuses that also makes them patently unsafe? How come you know something all the aviation authorities that accept Airbi as safe and sound aeroplane don't? Did you inform the relevant authorities or you just shared your discoveries with us on PPRuNe?

Good you can't believe it as they didn't. It is not overly hard to understand it, for Airbus pilots, that is.

The mistakes were made by the pilots, though.

I'm sure they will if you point it out to them using some good arguments.

Tough luck, all modern airliners, from Q400 to B748 have tapes instead of dials. Is it a conspiracy of about everyone making instruments or perchance there was some design forethought at work here and those tape-haters are just a loud minority, disregarded at no large cost, if any at all?

Of course it demands attention, after all it tells you what is wrong with your systems! It absolutely does not relieve you of duty to secure the flightpath before going troubleshooting.

We abandoned those in early 1960s, except for general aviation, some medium turboprops and technical marvels from Long Beach. Just watch the furious answers to this.

It is important to tell the difference between the airframe and flight control systems but anyway what's wrong with maintaining the flight path? Isn't it what the pilot is normally supposed to do, it's just easier with autotrim?

There is absolutely nothing religious about pilots' training. Nothing is dogmatic, everything is verifiable. Warning that flight directors will lead astray if in wrong mode is included in every training, as is inculcating the habit to constantly check FMA for correct mode and selected values. It is entertaining to read the outsiders' misconception on the way airline pilots do their job but it gets a bit annoying when such notions are stubbornly touted to be true.

Are you really suggesting that warning system going about their business contributed to sensory overload? How come other crews weren't sensory overloaded? How in the world can warning system help the pilot focus on flying? For Finnegan's sake, it seems as if you are suggesting that pilots need full-time electronic instructor telling them "Don't pull now... push it gently... easy... that's it". If you can't handle an abnormal now and then, you have no job being in the cockpit.

That describes every training program I was through in my life, from learning to write to basic infantry training. What is it supposed to do? Assume incompetence and demand non-compliance?

They don't use the same sound for TO config and excessive cabin altitude, don't they?

Look no further than 36 cases of UAS on 330/340 that ended uneventfully to see how ludicrous is to make sweeping statements based on just one case.

We who deal with aviation in our real lives are not looking for "cool", we are looking for safe, useful and economical. It might look "cool" for those who notice there's aviation going on only when something that pull their emotional strings happens, such as accident. Call Airbus cool if it makes you happy but that doesn't detract from the fact it is well designed, well built and safe aeroplane.

It may seem funny at first, but there do seem to be many people who really think this way, here and elsewhere
Not just funny, it is hilarious when posted on anonymous forum. It would be tragic if anyone who has some real connection with aviation would hold it to be true.

The whole point of AF447 is that it once again has proved for ignoranti that technology can not and is not designed to replace airmanship! Pilots are supposed to take over from auto-pilot anytime and fly safely if not with the same precision! Those pilots believing BS that technological advances changed flying by making basic skills obsolete are liable to get very surprised and possibly killed.

What I am seeing a lot in this discussion is another case of Carl Sagan's invisible, incorporeal, floating dragon that spits heatless fire and lives in a garage. Airbus has a lot of issues but what's the point of inventing them where there's none?

So, gentlemen, you have elicited the reaction. Happy now? May we have reasonable discussion back?
