Passing through DXB the other day, I noticed that all the parked A380s had their leading edge flaps* deployed. I didn't see any 777s, so not sure if they were the same.

Usually, the flaps are retracted on the taxi back to the terminal.

Anyone know the reason for this? I'm guessing it's temperature related, as it wasn't like that at MAN.

*Not sure flaps is the right word, but you know what I mean.
