Re: FAA Gives Final Approval to 777X Folding Wings

But to also be fair, the flaps are designed to operate primarily in a somewhat high-speed airstream (departure, approach, landing roll-out) whereas the wingtips will only operate at taxi speeds. So the loads they will be subjected to during their travel will be significantly less. Most of the flaps...

Re: FAA Gives Final Approval to 777X Folding Wings

To be fair, the big difference between these tips and flaps/slats is the motion. It's easy for the layman to feel that there's going to be a very large moment concentrated on a small hinge in the case of the wingtip, while other edge devices have loads more in-line with the wing structures, spread ...

Thanks for this. I don't want to be picky, but the said comment is a general statement about flight test aircraft, nothing specific about this flight.

Re: Airbus A321LR Seychelles to Toulouse Non-Stop 11 hours

In any case, it doesn't change the fact that the A321 is fuel limited and it runs out of fuel tank before it hits MTOW, hence the ACT's. And adding larger tanks on the wings would require a bigger redesign than Airbus was willing to do. A 3rd ACT on the LR already pushes it above MTOW with a full p...
