Captain COOL! WOW, he barely raised his voice. Incredible pilot.

My guess is that they all are Incredible and trained for such situations :)

 

But indeed, the pilot is cool although the footage seems to be incomplete. First he wants to bail out at 6000 AGL and later on he says he will try a last landing attempt. Somehow he managed to get at least basic controls of the plane.

Impressive recovery!

 

From the landing speed I got the impression the HUD was showing speeds in knots and possibly altitude in feet. Is Russia moving away from km/h in speeds and meters in altitudes?

Yea i noticed the same it looked more like the Hud of an US airframe.:huh:

HUD made by thales, so it's basically your Mirage HUD, so also the thrust indication on the top right. I really like the way the voice informer says: End the task (eject). On the Su-27, in the event of a complete hydraulics failure detection the Betty in there says something like "Angle of attack limit: no more than 10 degrees, if no adequate control can be established: eject!"

 

The Yak-130 guys had less luck, their FBW computer went haywire too, but the plane ended up uncontrollable in an inverted dive, so they did eject. Wonder if we'll ever see the tapes of that one. Believe it was prototype number 2.

The footage is incomplete, but it was shortened in the right sequence. He said that he wanted to eject in advance. (He says it several times, just to let the tower know what he was up to). He did not want to eject right away after he said so. And later he changed his mind and decided to land.

 

P.S. Roman Taskaev is a test-pilot of YAK-130 too. In 2006 he had to eject it with a co-pilot. Here you can see him talking about YAK-130 (starting at 03:42): http://www.youtube.com/watch?v=ITc9E5Vj2wU

Perhaps Taskaev had some deicing issues with control surfaces at 6000ft, ice melted partially when he descended and landing became a better option over ejection and airframe writeoff.

The temperature gradient is about 1 degree/300ft. The usual temperature in the Moscow region in August is ca.30 degree Celsius. He was only on 8000 ft altitude and ABOVE the clouds. The clouds are Sc, most likely because of the inversion on 4000 ft. It means that the air above the clouds is extremely dry. We can see that the visibility is 9999, maybe 30-50 miles. Even under the negative temperature the ice-building would be a miracle in such dry air. The temperature on the clouds level is about +15C. So, what kind of ice and deicing we can talk about?

1) 30°C is daily max temperature at Moscow it that time of year, can you tell me the minimal?!

 

2) HUD tape shows Taskaev having problems with controls at 6000ft, do you have any proofs that it was his ceiling for that day, can you say for sure that he never climbed above 6000ft to let's say 15000ft where the temperature drops to -12°C if 30°C at ground! Again let's say it was colder that day cause you can see a cloud overcast below 6000ft in that HUD tape.

 

Let's say it was 22°C at ground which means -20°C at 15000 ft.

 

So if he had icing at 15000ft and dropped to 6000ft do you really expect the ice to melt in a blink of an eye. Make an experiment at your home. Your average Kvartira temerature is guess what?!... 22°C and your freezer is set to average freezer temperature of -17°C. Place a plastic glass of water in your freezer and wait for an hour then take the glass out and count how long it takes to defrost completely.

 

Taskaev also said his FPM was pitching nose down and that's typical icing symptom. You see all the condensation that appears above the wing is likely to freeze and fill the upper slacks between elevons and wing pitching the elevons down. I had a similar problem with Cessna Citation CJ1 at 7000ft above island of Hvar and Brac in Croatian adriatic, and guess what it was 38°C at sea level!

Do you really expect that he had dropped from 15000 to 6000 ft in a blink of an eye? :)

 

In adriatic it happened to you because of high content of vapor in the air.

But in the continental climate, above the inversion, staying away from any clouds, you'll never have ice even in the negative temperature.

 

To have ice-building under -20°C you have to have really lot's of moisture in the air (clouds), because the big part of waterparts are ice-crystals already.

What seconds on the video does he say it?

You do not consider, speed of cooling on a metal surface, at constant having blown in a wind on speed of 500-600 km/h., at the discharged atmosphere.

Ok, I betray a secret. :smilewink: I know the reason of this accident from other Russian sources. It was a manufacturing defect. No ice, no human factor, no external factors whatsoever.

Can U share some details?!

 

It was the god damn 90s with the permanently dipsy president, and the nouveau riches, like Khodorkovski, Berezovski etc. who robbed the country and plundered its resources selling it to the West for their personal sake. Salaries were not paid over months, raped social system, inflation like in Zimbabwe, all state institutes were under-financed. Research firms were not an exception. Taskaev says about this accident: "It happened because we did not have money to check the plane on the diagnostic tester. That time all our thoughts were where to find additional 3 tons of fuel for the next flight."

 

Check this interview of Anatoli Kvochur. This interview was taken in 1996 and this few words describe that situation very picturesque:
