A single-engine airplane must be "trimmed" to fly level. (Trimming consists of raising one aileron and lowering the opposite one.) Why is this necessary? Is it necessary on a twin-engine plane under normal circumstances?

The single engine airplane must be trimmed to fly wheel to avoid wobbling of the plane. Trimming ensures that the any external torque on the plane gets balanced such that the orientation of the plane is maintained and there is no change in the direction of plane’s angular momentum due to the presence of external forces such as gravity.
