We had an Alert II here at RNO with an AA 757 landing with assymetrical flaps. The aircraft landed safely although it looked slightly crabbed on touch-down. I would guess that with one flap extended more than the other, you would have a different lift force on each wing, resulting in one wing being higher than the other. Would additional thrust on the opposing engine be used? Or is assymetrical thrust not a serious matter? What causes this condition-- hydraulic problem?
Thanks for any information.
