The 2019 Beechcraft Bonanza features Garmin Aviation's autopilot enhanced with Electronic Stability Protection (ESP) and Underspeed Protection (USP).
When a pilot exceeds user-selected pitch, roll or airspeed limitations, ESP and USP provide gentle movements on the flight controls to adjust the aircraft’s pitch attitude or bank angle, adding a wide range of flight regimes.
