Gone on the A340-5/600 and the A380 I believe.

I found out first-hand that the A340-500 and -600 still have the trim backup, and even despite their length, why wouldn't they? :ooh:

Remember that you still have hydraulics in the situation I described. Only if those would also fail the plane would be (almost) uncontrollable, just like any other Boeing, Fokker or McDoDo that has a powered control system relying solely on hydraulic pressure.

How they solved it on the A380-800, I don't know. But if it can be done on the A346 the A388 probably has it too, as the big bus is in fact shorter, reducing the cable length required. How else do you suggest Airbus will solve the problem of having no pitch control when none of the buses ( :O ) are powered? :hmm:

I think the DHL Baghdad A310 - missile - event clearly demonstrated the products controlability in extremis.

I am amazed that this accident doesn't receive more coverage on PPRuNe - its a bigger story than Sioux City yet the Skipper will never be a name like Al Haynes. Maybe it needed 200 people on board.

It was already decided that the 7E7 will not have a side stick.

Says who? Says where?

WWW: A missile strike is not something you take into account when designing your 7E7 or A380. I'm sure the relatives of those lost on Korean 007 and Iran Air 655 will be able to tell you that. :(

I'm sure the outcome of that particular DHL flight would have been a whole lot different had the IR-guided SA7 not hit the tip of the left wing but one of the engines, the tail or the pressure cabin instead. Nontheless, the crew did an excellent job on saving themselves and the plane against all odds, and I hear the A300-600F in question is in fact scheduled to return to active cargo duty as soon as she is sorted. :ok:

On another note, the DHL A300 lost all hydraulics and flight controls during that event and landed by using differential thrust alone. So I guess the stick-or-not-to-stick issue doesn't really apply here, but, you know, like, whatever... :E

I was under the impression that the 777 and the 7e7 were to be on a combined type rating as per the 757 and 767. IF the 7e7 were to have a side stick this surely couldn't happen. Bus as 747Focal says it seems it will have the good old yoke.

Expedite :ok:

The Airbus was FBW, with yoke, with no hydraulics. Ignore the missile cause but add in a raging fire. Consider low ATC assistance over enemy territory and the flightdeck confusion as to what could have caused such a set of failures.

They had no flight surfaces. Just differential thrust combined with a wing spar fire/severe damage.

They got it down.

Incredible.

A sidestick or a yoke made cock all difference.

A-FLOOR,

There will be no sidestick.

expedite-climb,

I believe you are right, though I have not heard that exactly. The reason you will not see a sidestick on a Boeing aircraft is all the Boeing senior engineers think that system is unsafe. That is probably a lot to do with "NIH". :hmm:

Nothing much changes

The first pilots given an ASI to help them avoid the stall said they were ceratinly never going to trust a thing like that when they could listen to the wind in the wires

You already said that. I asked you where you picked up this piece of information.

But never mind, as I guess because you state you live in Seattle, therefor you must work at Boeing as one of the lead engineers in charge of the 7E7, right? :rolleyes:

edit: a whole minute worth of Googling revealed this:

Hmm :hmm: :O

WWW,
The A-310 is NOT FBW.

Maybe A-FLOOR is right....Boeing may just have to take their pride and swallow it....

Plus its a great space saver....love the desk up front!:ok:

tmrmel,

I think you are going to get something to swallow. :E

A-F

Errr... I think not. Try a button on the sidestick maybe?

It's not a button to "get" manual control of the plane really - it's just a pretty bog standard autopilot disconnect button - just like you have on errr, a Boeing, MD and presumably Fokker...

NoD

NoD
 

I stand corrected :ok:

great one 747focal....how old are you???
Did i offend you in anyway? :confused:

...I was just sharing my view, no harm in that.

A-F...

The thing on the glareshield looks like a button, but is actually an indicator light. It is not used when you disconnecting the Autopilot, but when pressing the sidestick takeover button to "disable" the other sidestick...

NoD

tmrmel,

It was a joke. Sorry if it offended you.

No problems 747FOCAL, none taken.
I'm new around here so I just wasn't sure if that was the done thing

anyway.. back to the topic!...

NoD
 

You sure? :D ;)

As I probably won't be able to stand corrected one more time in a single topic :O
