Flaps..
Yes Airbus (330) docs say above 35 c in transit leave flaps at 1 for reduced overheat/ LE warnings.
So maybe a ccq issue with 380.
That said , it used to be the signal for hijack to leave flaps out after landing however that is probably redundant since 9/11. But certainly if you did it a few years ago in the U.S. ATC might ask about "ops normal".
And yes, as previous poster mentioned, contaminated runway landing maybe leave them out.
A 380 question - There was a recent case where a crew activated / left activated a crew pull - up smoke and fumes checklist ( apparently it is like the 777 where you can now request non-system detected checklists).
Great idea , but in this case the outbound crew perhaps didn't reset / deactivate it and it lead to the checklist popping up ( no CRC or MW as the system had not detected anything) .
They jettisoned fuel and landed in Hamburg where the engineers pressed the reset for them. Somewhat embarrassing!
Question for any 380 guys is: Is this a known gotcha,or would adherence to some SOP catch it?
