"Rumor is aileron feedback problem - system treated any aileron motion as external force, and attempted to "correct". Rudder was the only fully functional control."
Above was taken from Airliners Net, I"m not a Pilot so i don"t know how Credible that would be, i"ll leave that up to you Guys. |
"Rumor is aileron feedback problem - system treated any aileron motion as external force, and attempted to "correct". Rudder was the only fully functional control." That makes a lot of sense. When he was downwind, there were several wild yawing movements. It could well have been attempts to lift the port wing. |
Hello , I found some pictures here :

I cannot spot any emergency vehicles, neither in the videos, nor in the pics. I don't want to say that the whole thing is a fake, I think it as real, just wondering...
|
Why would anyone expect to see emergency vehicles in the pictures and videos we've seen so far?
It's a 10,000 ft (3,000 meter) runway and without flaps the plane was likely doing about 150 kts on touchdown. Where would you expect the fire trucks to be, and what are the odds they'd be visible in any given picture? And parked (large) aircraft hide a lot of the ground in most of the images. |
I think it's a fake. Just by the way it is filmed. Camera points to the ground just as it goes below the trees and come up again after landing. Looking closely the footage doesn't look quite right to me and as others point out, where are the emergency vehicles?
Plus footage of this miracle landing would have made the news and yet it isn't mentioned. |
That last photo has got me believing this being an actual event instead of some staged scenario. In which case my hats off to these guys.
I'm wondering if there is a way of diconnecting the hydraulic power to the flight controls in the 154. If I had something like this going on in a 727 I'd give extremley serious consideration to diconnecting the flight controls on the overhead panel and flying in manual reversion, significantly more control there than here if the artificial feel computer is going nuts. While it's true that it has that sense of a "viral video" (not seeing the moment of touchdown) when the camera points at the ground, given the vantage point I wouldn't have expected to see anything. The photos taken from a better point of view clearly show the touchdown though. |
Fake? Guys, please get a grip.
this happened on a military airstrip with an airplane used and owned by the military/government. There is plenty of photographic evidence as much as the 3 movies, they all correspond. Nobody knows what happened yet, it is questionable whether the Russian air force will ever publish a report about it, they are certainly not required to bring this into the open. However, Tupolev Design Bureau as well as MAK will want to know, as this type, at least the "M" Variant of it, is still used widely in passenger service. It remains to be seen whether what did happen occurred after lift off or even before, such as a maintenance issue. The aircraft had been stored for 10 years, run up last week and was supposed to do a first test flight when the incident occurred. Obviously, it will need another one once they set right what went wrong here. Rumours from Russia speak of a massive hydraulic problem. This makes sense to an extent, however there does not appear to have been a full loss of flight controls. At least part of them worked, as it is visible from the pictures. The landing gear remained extended, possibly planned but not necessarily so. The aircraft took off with flaps in normal take off position, but apparently landed without flaps extended. On the picture posted (no 11 in the sequence), one spoiler is seen extended as well as a slat. Especcially the lone extended slat is far from normal. So a massive hydraulic/flight control malfunction is certainly very likely. In more than one way, it is testament to how massive the Tupolev is built that it survived this. It is testament to the skill of the flight crew that they managed to get this aircraft on the ground and how they did. I do hope that the fact that this videos and pics have gone around the world will prompt the Russian Air Force to tell what really happened. I think they owe it to the crew to do so, so we may fully appreciate the extent of the emergency and how it was dealt with. |
Nasdrovie!
Taking the attached vid's with a few shots of frozen Stolichnaya! (rather than bait!) lol :eek:
Anyone see slats deployed? MAC (weight & balance issue?). I do remember a GF Tristar many moons ago in the sandpit with a forklift left in rear cargo hold which shifted on t/o. It made it back....... Who knows and not about to guess! :confused: |
Will the Tu-154 fly empty - or does it require ballast?
|
Fake? Guys, please get a grip. As to my previous statement/question... anyone know whether or not he flight controls on the 154 can simply be disconnected from the hydraulic system and allow the plane to fly in manual reversion. Being up front I'd prefer manual over wildly swinging powered controls. |
That landing photograph certainly doesn't look staged or fake. Some of the yawing moments caught on the video implied some big lateral forces on the tail fin as well. Why would any sane operator take such risks for a viral fake?
If this was a military "test flight" then are we likely to ever know the cause of incident? |
If this is RA-85563 as quoted (doesn't look like it in the pictures at reply 41, but it isn't clear), I don't think that it has been in storage for ten years.
I saw it less than three years ago being worked on and (although it doesn't look like it), it was in a line of active aircraft. This is the same line up which can clearly seen in the video's - the video's seem to be taken from the forward steps of one of the 154's? Also, from memory I don't think the touch down point would be visible from here so don't think there is anything suspicious about this. RA-85563-UUMU-25-07-2008 | Flickr - Photo Sharing! |
Why would any sane operator take such risks for a viral fake A well known "viral" video where no operator or military took any risk, just some CGI trickery. Like I said though, with photos of the landing I'm sure it was genuine. |
<<Why would anyone expect to see emergency vehicles in the pictures and videos we've seen so far?>>
One imagines that a maximum emergency status would be in force with safety vehicles positioned at strategic points along the runway. |
Declared a mayday on the VC 10 with a similar roll but not pitch problem.
We did a 180 and started to descend into thicker air hoping it might help the problem. In the end I took the autopilot out as we believed the aircraft would break up as the movement was causing ceiling panels to fall down. I had been taught to always leave it in as it could fly the aircraft better than you Sunny Jim. Motioned stopped. Runaway yaw damper but what mystified us is that there was no feed back through the rudder pedals (as we had with the Trident). The motion was very different to a trident damper runaway. Trident easier to diagnose as we had damper deflection indicators. Wasn't the same motion as dutch roll although fairly similar. Video looks like a rudder deflection problem followed by the secondary effects of rudder -as in roll and thirdly pitch. Shows how structurally strong SOME aircraft air...... |
That certainly looks very hairy and congratulations to the crew for their airmanship!:D:D
There used to be an Italian AF Captain (solo from the Frecce Tricolori I think), who performed a similar, madly gyrating circuit, finals and flare at really extreme pitch and yaw angles, which were only slightly moderated after landing on one mainwheel and then hopping to the other one, nearly scraping the tip-tanks in the process, but I doubt anyone would be daft enough to try that in a large airliner, even for a viral video!! The only concern I have about these videos! Plus footage of this miracle landing would have made the news and yet it isn't mentioned That point, along with why did he initially film what must have been a routine take-off, as it was hardly an ideal viewpoint for that kind of shot and surely this must be a regular occurrence to the point of boredom at such a location! Maybe they heard something unusual in the T/O run that caught their attention and possibly, if they were military personnel under strict control about where they can and cant go, he could only do the best from where he was! |
what mystified us is that there was no feed back through the rudder pedals |
A series of pictures of the landing, taking from the opposite side of the airport than the video. Click on the pic to advance.
Link Looks like a huge one-wing-down bounce there, on top of the other challenges. Tough iron, tough job to save the day. :ok: |
(Not directed at you SinoTC) |
There used to be an Italian AF Captain (solo from the Frecce Tricolori I think) Are you referring to this, SinoTC? Ciao, Ulxima |
Blacksheep - series yaw damper.
found that out the hard way. What surprised me was that the engineer who had double the experience of the two of us up front didn't know either. In the 70s there was a lot of ignorance in the aviation industry. In my view due to the lack of ability in those in management and training. Unfortunately it hasn't quite disappeared as we know about the 747 crew who didn't understand the basics of the cross feed system. Another lack of system understanding was when the fokker 100 was introduced in the 90s. We were told that it could not approach the stall because of the all talking full time auto throttle system. Second stall warning during low level final approach turns taught us not to believe what the brochure stated. |

Are you referring to this Apologies for the thread drift :) |

Man oh man, this goes down in the annals of airmanship - comparable to the guys for DHL in Iraq who landed an A300F without any hydraulics.
My butt is puckered just looking at stills. -drl |
I'll vote for an airmanship medal only after somebody confirms a failure mechanism in the aircraft.

Simply amazing! CG problem?
However, why is there no clouds in video #1, lots of clouds in #2 and scattered clouds in #3? |
glhcarl: "Simply amazing! CG problem?
However, why is there no clouds in video #1, lots of clouds in #2 and scattered clouds in #3?" Did you even bother to read the posts? Did you even bother to watch the videos? The CG problem answer is in the posts, the videos display no inconsistency in cloud type or cover. |
Boy oh boy oh boy........! It would have been mercifully brief for me, as coronary infarction would have occasioned long before the MLG finally reconnected with the TDZ.

@lomapaseo
the word is the plane's "stability and control augmentation system" was acting up. The Tu5 is actually a computer controlled plane, of sorts |
I remember some time in the late 80s or early 90s that there was another "crazy flight" display that existed, I'm pretty sure that it was done in an AlphaJet and may possibly have been a Belgian Air Force pilot or just maybe French.
I can't remember the location I saw it, but I suspect it was either Mildenhall, Alconbury or maybe the year that the IAT was held at Cottesmore although that is less likely as it was some years later, I think '98 or '99. |
I think what saved these guys was the Sen. Larry Craig "Wide-Stance" (TM) undercarriage on the TU-154. Surely a 727 would have caught a wing in the dirt. Still amazed at this piloting!!
-drl |
Having 12 main-gear tires instead of just 4 no doubt helped absorb the extra forces if the plane was trying to roll at touchdown. The -154 was designed for occasional gravel field use. :eek:
|
A video of the landing from the other side of the runway:
|
Interesting how one of the spectators shouts 'yes' in English!
Anyone able to translate the rest? |
They aren't saying anything interesting (what did you expect though?)
Something like this: Look how they... Go on guys, go on, go on What the... He has to go around again somehow, he is fully loaded No he has to land, no matter how, but he will break up of course He will strike his wing Go on guys, guess (a moment when to land) Go on That's all, he guessed! (a moment when to land) <Censored> Yes!! Well done! That's all I'm shaking in my shoes Did you film it? Yes They are heroes, they must be awarded <Censored> Those planes can't be flown anymore, get it? |
Those planes can't be flown anymore, get it? One wonders why they were trying to get this aircraft back into the air? |
I still say fake. This footage would have been on the news and in the press. It would have been a great achievement but nothing is mentioned. Fact is there are some talented people out there. Seen plenty of photo shop pictures done and they look amazing.
Not in the news so I don't believe it. This would be up there with the Hudson river in terms of skill. |
If you do the approach fron hell, say Funchal on a bad day, then watch the next aircraft land, it looks far less exciting from on the ground than it does on the flightdeck. So those gyrations were just too extreme to believe and I do have my doubts.
|
I get more fun out of the uber-skeptics - soon they'll be demanding to see the long form of the birth certifi- ooops, I mean, log book.
"I don't believe the video - it hides the landing." OK - here's the landing. "No, no, that's a still-picture series - I want to see video" Ok - here's video of the landing. "No, no, I want...." Giggle-heads. ;) |
