A method includes generating, in a normal mode, an aircraft power setpoint and an aircraft pitch setpoint based on a desired airspeed setpoint and a desired altitude setpoint. The method includes transitioning from the normal mode to an underpower mode when the aircraft is unable to maintain the desired airspeed setpoint. The method includes setting, in the underpower mode, the aircraft power setpoint to a full power setting, generating, in the underpower mode, the aircraft pitch setpoint based on the desired altitude setpoint, and transitioning from the underpower mode to an underspeed mode when the aircraft airspeed is less than an airspeed threshold value while the aircraft power setpoint is set to the full power setting. The method includes maintaining, in the underspeed mode, the aircraft power setpoint at the full power setting and generating, in the underspeed mode, the aircraft pitch setpoint based on the desired airspeed setpoint.
