Pressing the TOGA switch on the thrust lever will

• A. Disconnect the autopilot and establish GA mode for the flight guidance system
• B. Engage the autopilot in approach mode
• C. Increase thrust to maximum while maintaining current attitude
• D. Arm the flight director only

Answer: (A)

When you press the TOGA switch, you trigger a go-around sequence. The autothrust system moves to go-around/thrust maximum, and the flight guidance system switches to go-around mode, so the aircraft is guided into a safe climb rather than continuing the approach. If the autopilot was controlling the aircraft during approach, TOGA typically releases or disconnects it to allow the go-around to be flown, either automatically by the guidance system or manually by the pilot. This combination—maximum thrust and a GA mode activation—is why the correct outcome is that TOGA disconnects the autopilot and establishes GA mode for the flight guidance system. It’s not simply about arming the flight director, nor does it keep the same attitude or only engage an approach-mode autopilot.
