KC135777;
ALL swept wing jet aircraft will have some additional roll moment induced upon "decrabbing"
I think the point of the post was, Airbus WILL correct that rolling moment due to roll-control laws (as discussed extensively here) and Boeing will not correct the roll. I think we all agree that the aircraft will have a roll moment when de-crabbing, especially a swept-wing design.

My original point about some pilots believing that AB would "put the wing down" remains...some pilots believe that the airplane will de-crab and put sufficient wing down to continue tracking straight. Such an understanding is not correct.

The AB autoland will do this up to a point, perhaps because it has track-guidance, but it will land slightly crabbed, notwithstanding.

I think the post by Bernd, providing the Airbus Bulleting #54/2 (post #243) is worth reading closely.
