Sorry Tiger65, but you're spouting nonsense :=. All the data supports the fact that it hit allmost fully inverted. Whether it's roll was "only" 150 degree or it was full 180 degree it matters a little. There were two separate FDR's read by separate parities and they both agree.

The "working report" you cite is a a bad joke -- it's purely political job designed to muddy waters to consolidate deceased president's brother's party.

They found some phd from some american university to support their line? So what? Looking deep enough they could also find some phd from some other university claiming parapsychological reasons for the crash. There are some professors claimng and showing "proofs" that 9/11 was a inside job. Same quality of nonsense.

Gentlemen should agree not to use such utter political motivated rubbish as a data source...

karel and sebaska , you nailed it down and i fully agree with you. like said previously- all in all the mak report in my eyes shows the thruth.

maybe some minor, absolutely non essential details were not reported, but thats all.

its somekind discussion like the moon landing was a fake or 9/11 theories.

hm Moon Landing ? Landing is done on Land only. On Moon there is no Land. There must be only Moon there. Unless you mean Hollymoon oooops.. Hollywood.

Lets check who did read the reports :)

Question:
What was a roll registered by two separate FDRs?
(read and agreed by two independent parties)

Both FDRs register the same digital data. Analog data is converted to 8-bit digital by an ADC. 8 bit is quite coarse resolution, so each parameter has limits. Judging by abrupt evenly horizontal line at the end of the roll angle data on page 175 of English version of MAK report, FDRs record roll over the limit as the limit. But that's too complicated for conspiracy theorists. If you indeed are interested in anything else than ominously shouting "Russians did SOMETHING", read RTE (technical manual, not flight manual) what are limits of recorded roll angle. Yak-42 aircraft has similar FDR MSRP-64M-2, on page 606 of chapter 142 of its RTE the limit of recorded roll angle is specified: +-60 degrees.

MSRP-64 limit is +/- 82.5 degrees

Read what "tarirovka" is and think why the line at the end is evenly horisontal.

Lena you are a smart girl, so lets look at MRSP-64:
Item 10
https://picasaweb.google.com/lh/phot...eat=directlink
Item 24
https://picasaweb.google.com/lh/phot...eat=directlink
I repeat, the limit is 82.5 degrees
Data are read from both horizons.

Now, can you tell me why registered values stopped below 82.5 degrees if there was a barrel roll?

You don't listen, I give up.

Already did?

But yeah I'm sure the Russians created the fog and advising them to divert was all a big ruse to get them close enough to shoot down and make it look like an accident:ok:

Lena, do not give up :ok:
The horizontal line should start at around 82 degrees and not at 65.
Last recorded FMS event 15m above the ground which happend just moment before the first contact with the ground, registered 13 "visible" satellites and 11 "tracked". Is it possible to receive GPS signals during barrel roll with the inverted antennas?

absolutely yes since gps does not report sattelites in a second livestream. if you have a handheld gps you can confirm this by the following : let it establish satellites fully and report a position. then invert it and look that it takes a much more time than the whole crash to report you have the satellites lost- thats all about the gps conspiraton tiger.

I will not argue, that was a question - I did not know the answer.
However, Lena's " тарировка" (calibration) was out of scale even for the Russian standards :)

no problem, but the gps reading is really a non event. when it comes to the roll angle - i just looked at the fdr data of the mar report a roll angle up to 65 deg is shown and after that just the comment " extreme roll angle" . it seems for me- without knowledge of the tu 154 fdr, that it stopped reading above this value and the impact roll angle was estimated by debries/ ground damage / computing and not fdr values. but tiger... what difference does it make if theý hit the ground at 70 deg 120 deg or 180 deg?

it stays a fact that the pilot input was right aileron and the aircraft rolled ( due to the separated wing) to the left- so it was out of control . it may be like said 70 or 180 degrees, but it gives nothing vital to any "conspirancy" .

I am not a conspirologist, but the official findings don't match up.

The plane crashed with separated part of left wing. That's the fact.
As I showed above, there is no direct proof for barell roll as claimed.
Have you ever seen videos showing the planes hitting the ground with 65-90 deg roll? In Smolensk, there were shallow impact traces on the ground, no fire-balls and thousands of debris.

What is your personal view on that matter?

What is yours?

like said my view is pretty what we can read in the report. it seems the plane hit the ground first with the nose section since this section is completely destroyed . due to the fact that it has at this moment forward speed many traces are found and the debries is located in a wide area. due to the fact that first ground contact was made not with the stongest parts of the aircraft ( wing root, main undercarriage) but the "soft" nose the traces are shallow and simulatany it resulted in a real massive destruction of the aircraft. due to the fact that first contact was made with parts not containing the fuel ( it was in the wings and the center tank) as well they hit a "soft" ground without many sparks there was no fire ball but only some minor fires.

a barrell roll cannot be proved since the fdr does not record such but it also cannot be excluded and like said- its unimportant at which exact angle they hit the ground and i think they hit it pretty inverted.

a controlled flight into ground, thats all. surely no "help" from the russians to bring it down, no artificial fog, no bomb on board.

it maybe rises conspirancy theories since the place where they crashed and the reason for their visit is more than tragical irony , but it happend.

a far more interesting question is why all the flight crew , when trying somekind of a selfmade approach with the intention to go below published minimums even disregarded several "pull up" warnings.

Because the PIC heard such warnings during previous normal successful approaches to Smolensk-Severny, because the TAWS manufacturer forbade users to input into the airport database manually, because the American manufacturer wants more money for selling updates to the database.

It was not a normal flight where rules could be followed because:

1. It was a political mission to rub history to the bad Russkies. Therefore, all advice from the ATC's was suspect and subject to political interpretation by politicians who previously frequently insisted that it is them and not the pilots who have final say on everything.

2. The "Main Passenger" previously got rid of competent, experienced pilots after they refused to let politics override commonly accepted aviation procedures. The pilots at helm pretty much had no training and no qualifications to fly that plane, certainly not in these conditions and the only reason they were formally given that job was because there was nobody qualified left after the competent ones where "reassigned"

That's the core reason for the crash but if anybody brings it up the fanatics scream that this is politics. Well - it was from the beginning and it still is.

@ lena: that maybe an explanation regarding the TAWS, even when a strange one. it seems fact that this airport was not in the database.

thats another interestong story. from the summary of the mak report all crew members were bloody fresh on the tupolev in their positions. and this piece of russian metal seems to be a pretty complicated, not easy to fly aircraft. in civil life you would for sure not go leftseat on a +100tons airliner jet with this experience on type.

the first consequence is that the whole military department of VIP flights seems to be cancelled after this and the president or chancellor of poland are now flying with lot airlines aircraft, operated by civilian pilots.

the second tu154 stays in hangar after a completely overhaul , with brand new engines. and the crashed one had some over 100 flight hours after completely overhaul.
