What is the primary action to take if the aircraft experiences uncommanded yaw motion?

• A. Controls - Assume manual control and counter aircraft motion using handwheel inputs
• B. Yaw Damper, DISC - SELECT to disconnect both yaw dampers.
• C. Apply rudder pedals to counter yaw
• D. Engage autopilot to stabilize yaw

Answer: (A)

When yaw starts moving the aircraft on you, the quickest, most reliable way to handle it is to take manual control and counter the motion with direct control inputs. By assuming control, you cut through any uncertain automation and can respond precisely to what the airplane is actually doing. On the CRJ-550, that means using the handwheel inputs to apply the necessary deflections and work with the rudder as needed to oppose the yaw, keeping the wings coordinated and the aircraft on a stable path. This immediate manual correction gives you fast, predictable stabilization, whereas relying on automation or flipping switches can let the yaw persist or worsen. So the priority is to establish manual control and counter the yaw with coordinated surface inputs from the flight controls.
