IGh...just curious what amount of rudder displacement occured with those pedal movements..I don't know the airbus, but that amount of pedal displacement at relatively low speed doesn't sound like a tremendous amount..granted the rapid, cyclical inputs are puzzling...have only observed one pedal left-right or right-left rapid input and that is engine failure drills in the simulator after V1 when the wrong rudder is applied just prior to rotation..then its oops...other way and hold the pedal displacement..never to and fro.
