Why the A380 wiggles rudder so much on landing
I offer this theory, regarding the amazing amount of rudder movement during photographed landings of the A380...I do hope an A380 pilot will weigh in.
AGAIN, ONLY A THEORY:
I don't think it is anything to do with crosswinds. I think when the throttles are idled the engines don't come down at the same rate...perhaps the angle of the pilots hand not quite pulling throttles back.
anyway, the throttles and engines not coming back at the same instant (whether mechanical, electronic, or by hand) the plane wanders due to the assymetric thrust...then the pilot has to do a dance on the rudder pedals to keep the nose straight.
no proof, just a guess...I've seen pilots in other planes not retard engines/throttles and have to use rudder subconsciously to keep her going straight.
