To operate incorrectly in a go-around situation, which button would be essential to locate?

In a go-around situation, the most essential button to locate is the go-around button. This button is specifically designed for use during a go-around, which is a procedure initiated when a pilot decides to abort a landing and instead increases altitude and initiates a climb.

The go-around button typically triggers specific flight control systems that help manage the aircraft's performance during this critical maneuver, such as adjusting thrust levels and configuring the aircraft for climb. Understanding the function and location of this button allows a pilot to react promptly and effectively in time-sensitive situations.

In contrast, while other controls like the throttle button, speed brake, and landing gear switch play significant roles in different aspects of flight operations, they do not directly facilitate the go-around procedure. The throttle button controls power levels, the speed brake influences drag and speed management, and the landing gear switch manages gear deployment, but these functions are not specifically crafted for executing a go-around effectively.
