Which instability can arise when an aircraft's autopilot incorrectly interprets atmospheric turbulence?

💡 Explanation

Pilot-induced oscillation results because the autopilot's adaptive control loop, reacting to false signals, amplifies rather than dampens turbulence effects, therefore leading to divergent oscillations, rather than flutter which involves airspeed effects.
