What factors contribute to an airplane turning to the left in a nose high attitude?

When an airplane is in a nose-high attitude and begins to turn to the left, gyroscopic precession and engine torque are significant factors that come into play.

Gyroscopic precession occurs due to the rotating mass of the propeller. When the pilot commands a pitch change, such as raising the nose, the gyroscopic effect of the spinning propeller creates a force that can push the aircraft into a turn, affecting roll and yaw. As the nose moves upward, the propeller’s gyroscopic precession can cause the airplane to yaw to the left.

Engine torque refers to the tendency of the aircraft to roll in the opposite direction of the engine's rotation. For an aircraft with a standard clockwise rotating propeller, the left wing will tend to rise as a result of the torque effect, which, in a nose-high attitude, will contribute to a left-turning tendency.

The combination of these two forces—gyroscopic precession and engine torque—creates a notable left turn when the aircraft is in a nose-high attitude, enhancing the pilot's need to manage these forces effectively during flight to ensure control and stability.
