Salty wrote:Hey Adam...the amount of sag (flex) when at max take off weight with full fuel load in the A380-800 compared to in-flight as measured at the wing tips is not something I can find in a manual supplied to me.
At a guess I would say...about "that much".
Sorry. Smart@rse reply.
I feel like one of those pain in the backside kids you guys up front used to have to "inspire" during cockpit visits by putting up with endless questions - "Ah, Cap'n, how much does the wing flex?" . Just Googled it. I was guessing 2-3 metres, but it's a whopping 4 metres according to British Airways site - that is impressive! Looks like the 787 will do a staggering 8 metres plus flex. I remember watching a video of a 777 wing flex to destruction test. The wing tip was almost vertical when it blew apart in the test rig.
Here's another great feature of a A380 not mentioned anywhere. It's sensational for taking a 2 y.o for a walk. Those without kids won't know that 2 y.o kids have a attention span of about 30 seconds! So, unless eating or asleep, they get pretty restless. I actually felt I once walked halfway to Europe when pax'ing on a A380 and walking the kid - down the top deck, down the stairs, along the bottom and repeat in reverse order hundreds of times! A380 - big tick from parent when long hauling little ones!
