Particularly when airspeed iinstrumentation flawed by e.g. ice 2015-01-20 21:17 also, the pilot was extremely experienced. former fighter pilot, etc. the sort of AF447 mess seems extremely unlikely there. 2015-01-20 21:17 hmm, sound reasoning 2015-01-20 21:17 but why the crahs after that extreme climb then? 2015-01-20 21:19 AF447 the pilot wasn't even in cockpit afaik, he joined later (pissing? coffee? sex?) and failed to grok the situation 2015-01-20 21:19 the plane may have ended up at a place where it couldn't fly on its own. or maybe it suffered structural damage as a consequence of that ride. 2015-01-20 21:20 structural damage from winds? not heard of during last ~50 years, right? 2015-01-20 21:20 well, the PIC was out of the cockpit. but also note that AF447 was a long flight. QZ-8501 was comparably short. so they didn't need to rotate the cockpit crew. 2015-01-20 21:20 (except during landing) 2015-01-20 21:22 hope they soon will decode the voice recorder 2015-01-20 21:25 (structural damage in flight) doesn't happen often, but it does happen. also, there have been numerous incidents in the preceding weeks just in the general area with severe turbulences. so one can assume that the conditions were worse than normal for the season 2015-01-20 21:25 however >>the aircraft was climbing at a vertical rate of up to 6000 fpm exceeding the aircraft's capabilities, its airspeed decreased and it appears the aircraft entered a stall<< sounds exactly like AF447 2015-01-20 21:26 extreme conditions been what canceled out the autopilot on AF447 2015-01-20 21:27 afaik 2015-01-20 21:28 (conditions) here's a nice structural failure example. happened at low altitude, but still (look at the pictures): http://aviation-safety.net/database/record.php?id=19930331-0 2015-01-20 21:29 AF447 was fully flyable at the time it stalled. QZ-8501 may not have had that luck. 2015-01-20 21:29 W*T*F?! 2015-01-20 21:30 and yes, pilot overwhelmed when the AP disconnects is a surprisingly common cause of death 2015-01-20 21:30 but the again, this was a pilot with real flying experience. not just "take off, turn on AP, take a nap, autoland, go home" 2015-01-20 21:31 hehe 2015-01-20 21:32 of course, even experienced people can make mistakes. but in this case, it doesn't look like a basic aviation failure like in AF447 2015-01-20 21:33 as scary as all AF447 series of events was, my first reaction been "I prolly had shut down all instrumentation and flew the bird from my ass sensors only" 2015-01-20 21:33 (virtually shut off, read 'ignored') 2015-01-20 21:34 I mean, you literally _hear_ a difference between low speed stall and high speed stall 2015-01-20 21:35 (turn off instruments) that's surprisingly difficult ;-) http://avherald.com/h?article=47d74074&opt=0 2015-01-20 21:36 I don't believe in a 150dBm stall warning + extremely high speed display when my ears tell me the thing almost standing still 2015-01-20 21:36 (difficult) thus virtually 2015-01-20 21:36 not sure how reliable your senses are. also considering weather and darkness. i.e., you don;t really know what you're flying into. 2015-01-20 21:37 well, in the case of AF447. QZ8501 on the other hand had daylight ... 2015-01-20 21:39 oh, and if you want fun, look at the video here (best enjoyed on youtube and in full-screen): http://avherald.com/h?comment=47f968b7&opt=0 2015-01-20 21:39 yeah, I know my senses, so that's prolly why I say so. A frequent pattern when I run into weird instrumentation readouts of any kind. I'd prolly trigger the sparks of my car engine manually when I suspect the engine control is doing nuts 2015-01-20 21:40 the #1 rule in aviation if you can't see where you're going is to only trust your instruments, not your senses 2015-01-20 21:40 hmm, damaged landing gear? Doesn't look unusual or spectacular 2015-01-20 21:40 guess there were many dead pilots who trusted their senses as much as you trust yours ;-) 2015-01-20 21:41 it's not the blown tires, it's the taxiing ... 2015-01-20 21:41 ooh, ignoring all rules? 2015-01-20 21:42 these dead pilots may be the reason why these rules are there ... 2015-01-20 21:42 "damg thing doesn't woll, give a tad more throttle!" 2015-01-20 21:42 yeah :) 2015-01-20 21:42 omg 2015-01-20 21:42 "dang thing doesn't roll, give a tad more throttle!" 2015-01-20 21:42 I doubt the pilot even noticed 2015-01-20 21:43 "let's just taxi with take-off thrust" :) 2015-01-20 21:43 just read the comments ;-) 2015-01-20 21:44 or look at this example of how little of an issue pilots do notice: http://avherald.com/h?article=47f95b98&opt=0 2015-01-20 21:45 (trust senses) look, the difference is: I only overrule the instruments when they act extreme (stall warning etc). When my senses act extreme while instrumentation is pretty normal, I'd never even poncer which to trust more 2015-01-20 21:45 ponder* 2015-01-20 21:45 hehe :) 2015-01-20 21:46 but yes, LH-1829 was a very nice example of what to do when the plane is acting weird. don't bother debugging the computer, just fly. 2015-01-20 21:47 I'm not going to fly head down thinking all horizons went mad 2015-01-20 21:47 exactly 2015-01-20 21:48 (not knowing LH-1829 case, just ack'ing the general approach) 2015-01-20 21:48 http://avherald.com/h?article=47d74074&opt=0 ta "search" 2015-01-20 21:49 LH-1829 was the 4000 ft dive, link above 2015-01-20 21:49 yup :) 2015-01-20 21:50 FL270 fett * 10? 2015-01-20 21:50 feet* 2015-01-20 21:50 or * 100? 2015-01-20 21:50 *100 2015-01-20 21:51 i.e., cruise altitude 2015-01-20 21:51 ... where nothing normally happens :) 2015-01-20 21:52 here's another nice accident. very unfortunately without pictures. http://avherald.com/h?article=46fadfa1&opt=0 2015-01-20 21:54 NB: in the comments someone explains that this aircraft has a wingspan of 34 m 2015-01-20 21:55 >> actually airbus should Have a simple computer protection override switch<< hehe! 2015-01-20 21:59 i guess it's a two-edged sword: airbus are pretty aggressive with automation, and i think this does make the planes safer. on the other hand, it also means that pilots with insufficient training can fly them for years without any sign of trouble. 2015-01-20 22:00 also the meaning of "insufficient training" suddenly changes when the computer can outsmart the pilot 2015-01-20 22:01 when APA(?) can force node down and pilot can't overrule that - e... :-(( 2015-01-20 22:01 nose* 2015-01-20 22:01 I shouldn't type today 2015-01-20 22:02 it's the ADRU that implements alpha protection (alpha being the angle of attack. i.e., the thing that was waaaay off in AF447) 2015-01-20 22:03 AOA 2015-01-20 22:03 yep 2015-01-20 22:04 no idea about all that, it's my friend and landlord who got a license, not me ;-) 2015-01-20 22:04 AF447: by the way, you may find this interesting: http://www.bea.aero/fr/enquetes/vol.af.447/videos/animation.deroulement.du.vol.mp4 2015-01-20 22:04 mentioned here: http://avherald.com/h?article=41a81ef1/0096&opt=0 2015-01-20 22:05 I think that's what he told me about - weird messy actions on horn (sidestick), right? 2015-01-20 22:05 i kinda wonder if the computers in the airbus also do a longer-term assessment of the effect of their actions. e.g., would LH-1829 eventually have stopped the descent on its own ? 2015-01-20 22:06 yup. and look at the angle of attack. 2015-01-20 22:06 sorry, mimetype odd, doesn't play in any video player on my machine 2015-01-20 22:07 that AF447 simulation reminded me a bit of how i "fly" in a flight simulator when i try it for the first time and haven't read the instructions 2015-01-20 22:07 (would have stopped) aiui nope 2015-01-20 22:07 download, then view ? 2015-01-20 22:09 the suppositious angle of attack? 2015-01-20 22:09 (download) meh! 2015-01-20 22:10 "open with" vlc 2015-01-20 22:19 FDCX_ has quit [Ping timeout: 264 seconds] 2015-01-20 22:20 FDCX_ has joined #qi-hardware 2015-01-20 22:24 bwoahh scary 2015-01-20 22:25 what's the A321 going to "do" when lft and right sidestick are diametrically opposite steering position? 2015-01-20 22:27 seems the pilots trained on a spaceshuttle ;-) 2015-01-20 22:28 though, only regarding angle of attack and sink rate/mode, not regarding taking into account the fact that such a critter reacts on steering like a wet sponge 2015-01-20 22:32 my friend told me there's just two things to care about, after making sure fuel=100% and liftoff: altitude and speed. lots of both 2015-01-20 22:33 I really don't understand what the pilots tried to do. Why didn't they push throttle to max and nose down? 2015-01-20 22:34 I mean, even in their coffe cups they must have seen that the plane is nose-up or at least not too much nose-down 2015-01-20 22:35 and the airspeed meter was between 60 knots and zero most of the time, right? 2015-01-20 22:36 did they just check altimeter and conclude they need to pull up to stop decline? 2015-01-20 22:37 don't pilots train to get a plane out of stall? 2015-01-20 22:38 they must have been in that situation in simulator before, no? 2015-01-20 22:46 (two things to care about) that's the aviation part. you may also want to pay attention to navigation from time to time. especially if you live in a mountainous area :) 2015-01-20 22:47 there seems to be a specific "unreliable airspeed" procedure that would have saved them. why they didn't will remain their secret forever ... 2015-01-20 22:49 (opposed sidestick) that's when you get the "Dual input" warning 2015-01-20 22:56 (spaceshuttle) even for that the "landing" procedure would be incorrect - way too low airspeed 2015-01-20 22:57 (dual inp) I guess captain's sidestick rules then 2015-01-20 22:57 hmm, maybe not 2015-01-20 22:57 FDCX_ has quit [Ping timeout: 272 seconds] 2015-01-20 22:58 I bet there's some other weird rule that aims to cope with erratic input from epileptic attacks, defect sidestick, et el 2015-01-20 23:02 SyntaxTerror has joined #qi-hardware 2015-01-20 23:11 wej has quit [Ping timeout: 250 seconds] 2015-01-20 23:13 FDCX_ has joined #qi-hardware 2015-01-20 23:15 SyntaxTerror has quit [Quit: My MacBook Pro has gone to sleep.
