What defines when GA thrust is set automatically on EICAS?

Setting GA (Go-Around) thrust is an important aspect of aircraft operations, particularly during critical phases of flight such as takeoff and landing. The correct choice indicates that GA thrust is automatically set when TOGA (Takeoff/Go-Around) is activated while the aircraft is in a cruise (CRZ), climb (CLB), or continuous (CON) power setting.

Understand that "TOGA" is a setting used when a pilot needs maximum thrust to respond to an unexpected situation, such as go-around maneuvers when landing or needing to gain altitude quickly. In this scenario, whenever TOGA is engaged from flight profiles where the engines might not be operating at maximum thrust, GA thrust will be activated automatically, ensuring an adequate power response without any additional pilot input needed. This functionality enhances safety by enabling immediate thrust adjustments as needed based on the aircraft's state.

The other choices do not address the automatic setting of GA thrust in the same way. For example, simply having gear up and no flaps or the condition of N1 exceeding certain values does not trigger GA thrust unless explicitly combined with TOGA activation. Thus, the definition of the automatic setting hinges specifically around the operation of pressing the TOGA switch in designated flight modes.
