Name a significant risk associated with multi-engine flying.

The significant risk associated with multi-engine flying is asymmetrical thrust leading to loss of control during an engine failure. In multi-engine aircraft, when one engine fails, the thrust from the operating engine can create a yaw moment that pulls the aircraft towards the inoperative engine. This situation can result in a loss of control if not properly managed, particularly during critical phases of flight such as takeoff and climb. Pilots must be trained to recognize this risk and to use appropriate techniques, such as activating rudder input to counteract the yaw and maintain control of the aircraft. Understanding and effectively responding to this risk is crucial for safe multi-engine operation.
