What effect does an inoperative left engine have on the tail of an aircraft in relation to pitch?

• A. Increased lift
• B. Decreased negative lift
• C. No effect
• D. Increased drag

Answer: (B)

When a left engine becomes inoperative in a twin-engine aircraft like the Beechcraft Travel Air BE-95, the effects on pitch and control surfaces are significant. Specifically, the decrease in thrust from the left engine can cause the aircraft to tilt or yaw towards the inoperative engine due to the asymmetrical thrust. To maintain controlled flight, the pilot typically has to apply right rudder to counteract this yawing tendency. As a result, this yawing effect can lead to an increase in negative lift on the tail. The tail is designed to provide stability and keep the nose of the aircraft level in flight. With one engine down, the aerodynamic balance is disrupted, and the tail may experience a greater downward force to provide the necessary stability and counteract the yaw. This increased downward force translates into decreased negative lift, making it more difficult for the tail to maintain a level attitude. Thus, understanding the dynamics of thrust and how it affects the center of gravity and pitching moment is crucial for pilots to control the aircraft properly in a multi-engine scenario.
