Boeing 777 Spray Test

[Tjita1]

On the A380 for example, the spray test broke the brakes on one of the landing gears. Not good.

such a sexy plane...

Err, i'm not too experienced in airplanes, what was the point of this test?

[Danusha7800]

An airplane drives through a "puddle" of water to see if the splashes cause any failures, for example, get into the engines and stall them.

[op3l]

Ah i see. Thank you very much :)

@op3l

it tells you in the video if you were listening.

[RainbowManification]

@op3l if water would of went into crevaces in the exterior of the aircraft it could freeze at high altitudes and jam the controls, this was to see that it wouldn't do that

awsome

nevermind, my sound was messed up. (figured I'd come forward before the flaming began)

[b1cc2]

what in the hell is the spray test?

[supertamal2000]

I suppose to test the water effects on the plane?

[tastejones]

Its to do with contaminants on the runway and the effect on braking/handling of the aircraft. a small layer of rain only a inch think is a issue for airliners as it lengthens the landing distance or can lose control of the plane and it could slide off the runway. Testing like this allows them to create the guide for pilots to come on what is recommend that the plane can handle.
