What is the thrust asymmetry limitation in the CRJ 200?

In the CRJ 200, the thrust asymmetry limitation is set at 10% thrust difference between the two engines. This limitation is established to ensure safe and controlled flight, particularly during critical phases such as takeoff and landing when engine power is crucial for maintaining directional control and stability.

When thrust is asymmetrical, it can create uncommanded yawing moments that may lead to difficulty in controlling the aircraft, especially at lower speeds. Therefore, maintaining a limited thrust differential, such as the 10% threshold, helps pilots manage these challenges and reduces the risk of loss of control. This limitation is based on extensive testing and operational experience to ensure the safety and reliability of the aircraft's performance.

Considerations for thrust asymmetry are crucial in operational procedures, and exceeding this limit can lead to significant handling difficulties, which is why knowing and adhering to this specific limitation is important for pilots flying the CRJ 200.
