What is the T-6's maximum airspeed for yaw control?

The T-6's maximum airspeed for yaw control is 200 knots, which is the correct answer. This limit is set to ensure that sufficient control authority is available for effective yaw maneuvers, especially during critical phases of flight where adverse yaw can significantly impact handling characteristics.

Operating above this airspeed can lead to reduced effectiveness of the flight controls, especially the rudder, which is crucial for countering yaw induced by roll inputs or asymmetric thrust. At 200 knots, the aircraft maintains the designed control inputs within safe operational limits, allowing the pilot to manage yaw effectively without risking loss of control or increased workload during maneuvers.

The other airspeed options are either below the functional limit or suggest an inability to maintain optimal control fidelity, which could compromise aircraft handling and safety.
