A320 over controlling/PIO fix.

Hi Vessbot

FCOM explains it better. “With the sidestick at neutral, wings level, the system maintains 1 g in pitch (corrected for pitch attitude), and there is no need for the pilot to trim by changing speed or configuration. Therefore pilots only need to perform minor corrections on the sidestick, if the aircraft deviates from its intended flight path. [bold]If the pilot senses an overcontrol, the sidestick should be released.[/bold]

Pitch trim is automatic both in manual mode and when the autopilot is engaged. In normal turns (up to 33 ° of bank) the pilot does not have to make any pitch corrections once the turn is established.”


So stick free and with wings level the system maintains 1g.
With up to 33° of bank, the system will maintain 1g in the vertical direction but the wings will be pulling >1g due to the centripetal acceleration in the horizontal plane.
