Plain English Meaning

When the pilot moves the control wheel or stick sideways, the ailerons on the wings move and the airplane rolls. "Aileron inputs" simply means those sideways control movements the pilot is making to bank the airplane.

Full Definition

Pilot-applied control wheel or stick movements to the left or right that deflect the ailerons, producing roll about the airplane's longitudinal axis. Aileron inputs control bank angle and are used to enter, maintain, and exit turns, and to correct for unwanted rolling tendencies.
