Landing Distance SU 27 Flanker

[nomorecatering]

Does anyone kow the landing distance, runway length reguired for the Flanker with brakes only, no drogue shute. Have seen the Pride Aviation video and its landing run seemd rather shorter than I expected.

Is a 1500m runway adeguate?

Checked my POH but cant seeem to find the distance without shute

Ask Neville.

He'd know. He'd need to. That's why he'd know.

There are many Su-27 variants. If the vid you have allows you to see the nosewheel and it has a brake then that gives better braking performance than most rear wheel braked aircraft. (Think front wheel on your bike compared to back wheel) When we added a nose wheel brake to a Hunter it had the same effect as using a 'chute. Half of Farnborough's runway was enough during many Su-27 displays.

John,

I'm sure you'll remember this : YouTube - Su-27 Flanker (http://www.youtube.com/watch?v=mokhjC5YQhM) :ok:

Really must get around to downloading a full length / high quality copy onto Youtube sometime but this will have to do for now.

nomorecatering, as John Farley says, there are so many variants / sub-variants that it's difficult to even estimate precise landing distances. Some of the variants seen at airshows, such as the above, were actually slightly stripped down / basic versions, as was 598 and her sisters 595 and 597.

I recall that the (Su-27) / Su-35? variants which displayed at Farnborough carrying a full warload required rather more tarmac to come to a standstill than the one in this clip which is hardly surprising.

However, appearances / video 'evidence' of stopping distances can be deceptive. At certain places we filmed them, like Zhukovsky, the runway was so long, and dosh for replacement parts (like new brakes) was so short, that they hardly used the brakes at all and just relied on the length of tarmac to slow them down.

Landing distance is a very big example of what you can demonstrate at an air show (or put in the brochure) being very different from what you'd actually want for sustained operations.

That said, it's really a factor of approach speed (where the Su has the wing and controls to be quite good), brake capacity and the ability of the controls to put weight on wheels. The 'phoon, incidentally, has fan-cooled brakes so it can turn around quickly after a short landing.

Yes Ta. That was of course Anatoly Kvotchur. As good as any lad in that class of aircraft. So consistent throughout the week. Quite a reined back display compared to Biggin (He always realised that the FCC had a tough job at FY and never gave them any trouble).
