What action does a pilot take during a climb?

During a climb, a pilot typically adjusts the throttle to increase engine power and provide the necessary lift to ascend. By advancing the throttle, the pilot ensures that the aircraft has sufficient thrust to overcome its weight and any drag produced during the climb. This action is crucial for maintaining the desired climb rate and airspeed, making it a primary focus during this phase of flight.

While other actions like engaging the autopilot or retracting the landing gear may be part of standard operating procedures during different flight phases, they are not specifically required for or directly associated with the climb. Advancing the flap is typically not done in a climb; flaps are usually retracted to reduce drag once the aircraft is safely airborne. Thus, adjusting the throttle during a climb is essential for optimal performance and safety in flight.
