Most commercial airliners nowadays do not have any such cables. 747's have hydraulics only. You have to go back to 737's to get actual cables that will move the surfaces.

mpohl 1 #28 June 2, 2009 Maybe it's just because I was on a transatlantic flight myself three hours ago (!) while Air France was going down. And no, you don't have to sing hymns, praise humanity, and such. BUT MAYBE, JUST MAYBE show a little bit of human decency and compassion!!! Is that too much to ask? What if it were you baby daughter, your mother, your brother, your wife? Quote Quote +1 I am constantly surprised and appalled by the level to which people can sink on a public forum. Quote 1) I can not believe how glib some of you heartless bastards are. Hundreds of people just died. Grow up. 2) I doubt this is electrical or engine related. My guess is we're looking at an in-flight breakup. Oh give me a freakin' break! What, we're all supposed to be 'Oh the humanity' and sing 'We will overcome' in unison? We lost over twice that many people on U.S. highways over the Memorial day weekend, where was the outrage and the sympathy threads over THAT? We on this 'public forum' jump out of airplanes, banter about sex, drugs and An-2's all day ~ and you're appalled? Suck it up cupcake. Quote Share this post Link to post Share on other sites
mpohl 1 #29 June 2, 2009 The first "fly-by-wire" tragedy was a a broken line on a parachute. Take your pick! Quote I almost hate to say it, because I'm all for technology, but what I think we have here is the first true "fly by wire" tragedy. We've all seen this Airbus crash http://www.youtube.com/watch?v=SCwYAzqvcrQ which really didn't have anything to do with the aircraft, just daft pilots, but in the end I want steel cables between my hands and feet to the aerilons and rudders - not just electrons thank you!

riddler 0 #30 June 2, 2009 QuoteI almost hate to say it, because I'm all for technology, but what I think we have here is the first true "fly by wire" tragedy. I'm not an expert, but I doubt it. Most fly-by-wire systems are triple or quadruple independent redundant systems. I used to work at a corporation that manufactured military jets, and anytime someone mentioned fly-by-wire, it was preceded or anteceded by "x-redundant". The first thing people would question with the systems was "what happens in signal-loss?", and I guess the insiders got so tired of it, they started mentioning redundancy at the same time as they mentioned fly-by-wire. Lightening could take out three or four-redundant systems, but I'm inclined to believe that something else happened.Trapped on the surface of a sphere.

JohnMitchell 16 #34 June 2, 2009 Quote I figured if it was down they'd get the ELP signal. Such was not reported. It's ELT signal. emergency locator transponder. I don't think the big planes are required to have one, and they don't work from underwater. Quote Share this post Link to post Share on other sites
JohnMitchell 16 #35 June 2, 2009 I believe the A-320's had a back up mechanical throttle and rudder system that you could somewhat control the airplane with no electrons doing their thing in the black boxes. Don't know if the jumbo heavies have anything like that. Quote Share this post Link to post Share on other sites

Sort of. I think there is a manual trim-tab drive on elevator and rudder, but even that needs hydraulic power. Quote Share this post Link to post Share on other sites
ZigZagMarquis 9 #39 June 2, 2009 Quote Quote I for one became a bit skeptical running twins over the pond WAY back when, especially heavies. So you tried to talk that Lindbergh kid out of trying it with just one? Well, an advantage of a single engined aircraft is that the emergency procedures are simplified immensely vs. that for a twin or multi-engined aircraft if the one and only "spiny thing" stops.

One disintegrated fan disk took out all three hydraulic systems. Not impossible that some kind of electrical event might take out redundant electrical systems. When I was at a defense contractor, I was startled to see 4 redundant roll-sensing gyros tucked together on a bulkhead.

LyraM45 0 #47 June 2, 2009 Quote "Flight - try SCE to AUX." Apollo 12 lightning strike... the rookie alan bean ended up knowing that sequence when the old timers didn't. I like your space nut thinking... On a less lighter note... I was forecasting last night at work, and I had two flights that were routed in the same area as this airbus. (my forecasting is for corporate jets... much smaller, but still not immune to same weather effects the airbus might have experienced) I checked the data after I heard about this accident this morning, checked reports from our clients, and all this stuff on the news about severe turbulance seems pretty bogus to me. Yea, sure, they were flying around convective thunderstorms, but nothing out of the ordinary, especially for a big boy jet like the A-bus. I really have a feeling, if we find out at all, that there was something else to this. If it does in fact end up being because of a lightning strike that threw everything offboard, then I'd like to know what was wrong with the aircraft to have such a catastrophic failure with something (a lightning strike) that is usually not such a huge issue. No matter what, its still a really really sad day. Apologies for the spelling (and grammar).... I got a B.S, not a B.A. :) Quote Share this post Link to post Share on other sites

LyraM45 0 #50 June 2, 2009 QuoteI believe that people underestimate the possibility in-flight break ups due to turbulence. short of flying into a lenticular cloud at that height, or the anvil top of the CB's at flight level 420 (which is the tops the radar indicated...typical in that region this time of year), which the aircraft had no business being around if that was the case, it would take a hell of a lot of turbulance at that flight level to rip apart an airbus. Now, at lower levels, you can consider other things to down a plane (IE: microbursts, etc), but this was not the case. There's only so much that can go on at the upper levels of a long range cruise.Apologies for the spelling (and grammar)....
