Which phenomenon increases turbulence around the tail when one engine fails?

• A. Torque
• B. P-Factor
• C. Accelerated slipstream
• D. Spiraling slipstream

Answer: (C)

The phenomenon that increases turbulence around the tail when one engine fails is accelerated slipstream. When an engine fails, the thrust produced by the working engine predominantly affects the airflow around the aircraft. The operating engine continues to produce a slipstream — a high-speed airflow that wraps around the aircraft. As the aircraft operates predominantly on one engine, this accelerated slipstream can cause a significant change in the airflow characteristics, particularly around the tail section. The airflow becomes more turbulent on the side of the aircraft with the inoperative engine due to the imbalance in thrust. This turbulence can compromise control effectiveness, especially in a multi-engine aircraft like the Beechcraft Travel Air BE-95, which is designed to operate effectively with both engines. Understanding the implications of accelerated slipstream can help pilots manage their aircraft more effectively in the event of an engine failure, ensuring they maintain control and stability during critical phases of flight.
