Ban them form western FIR's?

I'd put money on it that it was a government charter!

In light of reporting the BOTH a TODA and a TORA, I will conjecture that the TO may have been perfectly OK...depending upon what was the limiting case AEO/OEI and the size of the TODA [remembering that this is a quad---for first segment considerations of the OEI case] ----and also observing that Vlof was achieved by the end of the runway then

--either---
1. the margin on the AEO case was contained within the clearway
2. the OEI case was predicated on a clearway---but at the end of the TODA ---but how much of the APRT boundaries were declared a clearway?

we simply don't have enough information to conclude anything regarding the legalities of that TO other than that it looked interesting!

So if it took all the runway on four engines to accelerate to Vlof, would it have been able to do the same had it lost one engine at V1?

Best foot forward: Sometimes the all engine acceleration is more limiting due to the greater distance traveled with all four donks turning, also the all engin speeds [V3 and V4] are greater perhaps creating further distance or climb gradient limitations---

I'm unsure about what exactly the whole 3rd world thing actually means but one thing is for sure; a huge proportion of the russian population are very poor indeed. It's a country where bribery gets you by, the press are tightly controlled by the government (a few journalists with a habbit of publishing embarassing stories have a funny habit of getting bumped off), and democracy is virtually a sham.

I'm unsure what implications all this has on Russian aviation but it can't be positive thats for sure.

There are a few Russian comments in this video , which one of the others linked me to... I did like the first high speed pass, but the Go-arounds??????

http://www.youtube.com/watch?v=MCF04ixE5ks

Unsure of the aircraft or airline though... Maybe someone can help?

So, back to the original thread, Am I right that, by looking at the climb performance (marginal). The pilot could have calculated correctly, as he only had to achieve only half of the air distance to 35' by the end of the runway, muliplied by 1.15(may have forgotton this) ((unsure of the 1.15 for this type))

Looked pretty exciting either way!!!

This is a TAP (Air Portugal) Airbus 310-300 in Lisbon. The Chief pilot was at the controls. I landed there not too long after this video was taken last summer and I was handled by a TAP mechanic. He explained to me that the airport is 300 feet AMSL and that right off the far end of the runway, the terrain slopes down steeply toward the bay which is just a short distance away. From where the cameraman stood, it looked like the A-310 was much closer to the ground when he banked away because he had not yet climbed away, but the ground had lowered below him. He was low, but no where as low as the video lets you think. That low downwind leg was over the ocean which cannot be seen in the video.

Thanks Minorite... I thought that it was some sort of Airbus..

Looking at the video again, you can see that the wing does not go close to the ground I originally thought... It was still very low.

You might be interested in this thread for some different opinions, if you can manage to read it all without losing the will to live.

Talk about needing the full length

I'd love to see their numbers for that takeoff!

I am a little surprised that nobody seems to have considered that the crew deliberately did not rotate until the end of the runway - from what I know of one or two Russian pilots that would have appealed to their sense of humour.

If they actually were running out of runway and dragged it off in desperation at the end I would have expected a faster rotation to a higher nose attitude.

There are wind up merchants out there in real life not just on the internet.

Errmm, any examples of this phenomenon? Just interested...

Isn't the all engine case sometimes more limiting as you have to add a safety factor to it? (As the all engine case is so likely, and the OEI case very unlikely)

The engine out case can just be the net performance if I remember correctly (and I probably can't).

i.e.

4 engine TOD required = 1000m
3 engine TOD required = 1100m

1,000m x 1.15 = 1150m, more limiting than the engine out case.

Fullwings, If I dig out my old 707 AFM perhaps I can find A few cases where AEO limits TOD instead of OEI as this phenomenon was a common occurrence in older type

Jb5000,the TOD listed in the AFM already accounts for the 15% margin on the most limiting case

so, if TODR =1000m then TOD =1000m and the TODA must be at least 1000

I have watched a couple of IL76s take-off from Amman(Marka) - runway 24looks like a ski slope - and the video has pretty much the same profile. The only difference at Marka is about 8 miles of dense housing in front of and beneath you.....
