A380.
Not sure which forum to post this in, so Mods, please move if necessary.
Last month my son flew on the Air France A380, Heathrow-Paris-Heathrow. He took some fantastic video out of the window. One thing puzzles us.
On the trailing edge of the wing there are three nacelles. The centre one has what looks like a valve ? Now what is it ? Is it to allow fuel to be dumped in flight ??
Thanks,
Clint.
