In a climb, advancing the power control lever (PCL) will result in yawing to which direction?

In a climb, advancing the power control lever (PCL) increases engine power and thrust. This action can create a yawing moment due to the asymmetrical thrust produced by the aircraft's propeller or jet engine. If we consider a typical aircraft configuration with a clockwise rotating propeller, increasing power causes the airplane to yaw to the left, primarily due to the increased effects of P-factor (where the descending blade produces more thrust than the ascending blade) and torque reaction from the engine.

This left yawing tendency is particularly prominent when the aircraft is in a climb, as the angle of attack increases and the airflow changes, enhancing the differential thrust effect. Pilots often counteract this yaw with coordinated use of the rudder to maintain straight and level flight during climbs. Therefore, in this context, advancing the PCL indeed results in a leftward yaw.
