Small Flaps Under A380's Wing

Sun Nov 16, 2008 12:48 pm

I'd like to know what function do they have. You can see what I am referring to in this photo:

They are under the wing just in front of the engine (by the perspective of the photo, of course).

iirc, they are the presurisation dump ports or valves.

They do look like dump valves, though I would have thought that the dump valves would be further aft on the fuselage.

I think they are the AC/Pressurization system exhaust ports.

They appear to be too far outboard for pressurization valves.

Airbus usually puts the AC packs in the forward cheek of the wing/body fairing, although I'm not certain if the A380 did it this way. If they stayed true to form, these could be the pack cooling air vents.

The above data is Airbus proprietry information I suggest you delete it.

They are the ram air exhaust from the Air generation unit (Packs Outlet)
