Quote from andrasz:
"...and probably you could achieve a successful planned takeoff at 10 tons over MTOW, same cannot be said if speeds and flaps settings are based on a lower weight."

Agreed....

Thanks Karel_x,

I may be missing something, but so far I still did not recognise any debris from the left wing in any picture I have seen.

Hi Machinbird,

To be fair, I think other posters have previously speculated on both slat/flap asymmetry and premature retraction of slats and/or flaps.

I'd be interested to hear your opinion,...

Hi Machinbird,

Unfortunately, we still have no information on the dutch-rolling characteristics of the Tu-154 with the yaw damper system simply turned off. I was hoping a Tu-154 pilot might...

Thanks K,

So that's the starboard-side and fuselage wreckage laid out within a rough outline of the aircraft. It would be interesting to see what they've got on the port side.

I still don't understand this fully. Did the transposition of the wiring also stop the crew from simply turning the yaw damper off?

Is there an ON/OFF switch? Failing that, is there a CB?

Regarding the videoed dutch-roll incident, you mention crossed-wiring in the EFCS. We can presumably rule-out that...

Hi megan,

You've misquoted my question as an assertion! := For the benefit of any newcomers, this was my question:

Good evening Kulverstukas,

In the latest picture you have posted (in #372), is that the R/H (starboard) wing again?

If so, is the L/H (port) wing missing, or in small pieces?

On a completely different tack, are we to understand that, unsurprisingly, the TU-154 has a natural tendency to dutch-roll at low altitude, as apparently demonstrated in this video?

Kulverstukas,

With the photo of the back view of a wing in your post #351, you refer to it as the "sideboard wing". Excuse me asking, but do you mean the "larboard" (port) wing, i.e., the left...

Thanks again Kulverstukas,

Is that trailing-edge flap fully retracted? :confused:

Hola guadaMB,

Like lomapaseo I have never heard the expression "stall pose" in relation to an aircraft impact. I am thinking this may be used by personnel in your SAR work? Every profession has...

Even if the aircraft was airborne for the entire 70 seconds quoted, which is unlikely, it could not have completed a u-turn in such a short time.

Hi Kulverstukas,
Did you mean to say that the Tu-104 was an ancestor of the Tu-134? But they seem to a casual observer like me to have little in common.

Thanks for the drawing of the Tu-154...

I'm not promoting any theory whatsoever on this TU-154 accident but, FWIW, over the generations of jet airliners some T/O config warnings have been better than others - both in terms of the...
