Flaps...
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.

Slats. Might be temperature related, or maintenance but unlikely that they're checking that many aircraft at once. My first thought was to counter strong winds and stabilise the aircraft on the ground, but Slats increase lift, so that wouldn't make sense.

It was very calm. I noticed it initially when we left the plane on arrival at DXB. I thought it must have been a one off. But the following morning every A380 I saw (maybe 4) had them down.
I though slats were slightly different than flaps? Actually, I've just checked, and they're called "droops" on the A380.

It's an Airbus thing in high outside air temps. The flaps / slats are left in a certain setting while on the ground. This allows for cooling to stop a false air bleed leak warning.
Can't find the reference in the books at the mo but it's something like the above!

When temperature is 30 degrees Celcius or higher leading edge slats will be extended on the A380 (was the same on the 330/340).
I'm not exactly sure why but the power ports for each individual seat won't work, so you'll have to wait until after take off to be able to charge your devices.

The spoilers are lifted slightly during flap retraction. When I went through on Monday I noticed the flaps deployed to position 2. This isnt a normal A380 operations and must be specific to EK.
