Which outcome occurs when a commercial airliner experiences a 'hardover' event in its elevator control?

💡 Explanation

A 'hardover' means the control surface deflects fully due to hydraulic failure; it triggers a sudden pitch change because the elevator's aerodynamic force becomes overpowering. Therefore a runaway pitch is most likely, rather than managed responses from other systems.
