What rudder trim input is required if an engine fails with the autopilot engaged?

• A. None, the autopilot will trim automatically.
• B. No rudder trim is available, the pilot must use the rudder pedals.
• C. It must be trimmed manually.
• D. The rudder trim reset button must be pressed for 3 seconds.

Answer: (A)

When an engine fails while the autopilot is engaged on the A320, the autopilot system is designed to compensate for the asymmetric thrust caused by the loss of power. The autopilot automatically adjusts the flight control surfaces, including the rudder, to maintain the aircraft’s heading and to counteract the yaw induced by the engine failure. This capability minimizes the need for pilot intervention, allowing the aircraft to stabilize itself without requiring additional rudder trim input from the pilot. This automated response is crucial in maintaining control and ensuring the safety of the aircraft under such critical circumstances. Given that the autopilot system can effectively handle the adjustments needed, pilots can focus on other essential actions, such as configuring the aircraft for safe flight or preparing for a potential emergency landing. This highlights the importance of the automation systems in modern aircraft, which enhance safety and reduce pilot workload during challenging situations.
