What does that have to do with this thread?

 

Its a good video (and its not a weight and balance issue its a hot and humid day) but should be in the vids section...

On something like that, I think you would want to go a little bit faster than V1 for the takeoff roll...have ground effect work with you in helping create lift.

Actually I think its just that the Russian Take off certification for this type (transport) operation is different to that used in the "west". I don't think they need to account for the Engine failure GO case, as is required in the west.

 

In simple terms in the west one of your limiting take off weights is that you must be able to get airborne with an engine failure occurring at V1 and be able to clear the departure end threshold with a specified minimum wheel height. So you must plan assuming an engine will fail and reduce weight if required.

 

There are a number of similar videos/images around of Russian transport types using "curvature of the earth effect" to get airborne. If these guys suffered an engine failure it would have been a runway overrun or crash.
