Boeing 777 showing off final approach radical touch downs sliding skidding crabbing

what is the song called?

Awsome crab landings

What airport is this?

I do this in my 787 all the time!

with out batteries ?

Aren't the 777 parts of this vid from the Boeing 777 cross-wind testing? Well them and one lone 747 (0.27) prior to the Korean Air's alarming approach to Kai Tak?

Sideslipping! Isn't this were you cross the controls? Right rudder/Left aileron etc. I thought that was a technique for losing height quickly if you're too high on approach. Or do you have to use large deflections to do that, lose height that is?

Its not a C172, Boeing says that you do not have to land this aircraft with a sideslip in a crosswind.

The B777 has a max demonstrated crosswind component of 38kts, and the bank angle that would produce from doing a pure sideslip would scrap an engine nacelle. The tyres, trucks and landing gear are designed to be used like this.

Doesnt matter the technique used to accomplish it.

Not really. I do it in the 767/757 all the time. It can take the landing, and is certified for it.
