What is asymmetric thrust?

Asymmetric thrust is a condition that may occur during the operation of a multi-engine airplane, particularly when one engine fails or operates at a different power setting than the other engine(s). Asymmetrical thrust occurs when one engine produces more power than the other, causing the airplane to roll and yaw towards the side of the less powered engine. This effect can cause difficulty in controlling the airplane and can lead to dangerous situations if not properly addressed by the pilots. Pilots must be trained to handle asymmetric thrust situations and use proper techniques to maintain control during such situations. In extreme cases, if the airplanes' pilots are not properly trained to handle the situation, the airplane may experience an uncontrolled roll and crash.
