A320 aileron trim
Flying out of Heathrow on an A320 the other day I noticed that on the climbout a significant amount of left aileron trim was required to keep the aircraft wings level. Then in the cruise the ailerons seemed to be set with a slight right roll input, while in the descent rather more right aileron was required.
Why the changes? Are they airspeed-related? Or are there torque-driven trim changes with changes in power setting?Please help a poor confused SEP instructor.
