This evidence is consistent with the testimony of two pilots who participated in the wake vortex testing, who stated that the wake vortex encounter is not a disorienting event. USAir Flight 427s wake vortex encounter has relevance to the accident investigation only to the extent that it caused a momentary rudder input (by the flight crew or through the yaw damper) which, due to an unknown mechanical malfunction, translated into a hardover or reversed rudder.
