What procedure should be initiated to regain control during an uncommanded yaw in the T-6?

To regain control during an uncommanded yaw in the T-6, initiating counteraction with opposite control input is the most effective and immediate response. When a pilot experiences uncommanded yaw, typically caused by an asymmetrical thrust or a malfunction, applying opposite aileron input helps to offset the undesired yaw motion and stabilize the aircraft. This technique takes advantage of aerodynamic principles, allowing the pilot to regain directional control and prevent potential loss of control.

The other responses do not directly address the critical need for immediate corrective action through control inputs. Increasing airspeed could worsen the yawing motion, as higher speeds may amplify the effects of the issue rather than mitigate them. Reducing throttle does not necessarily resolve the underlying cause of the yaw and could lead to further complications, such as increased engine drag or loss of performance. Performing an emergency landing is an extreme measure that may only be appropriate after all other corrective actions have failed, and it is not a first step in responding to an uncommanded yaw. Thus, the most appropriate and effective initial action is to apply opposite control input.
