Which factor increases drag on an aircraft during slow flight?

• A. Increased lift drag ratio
• B. Decreased lift drag ratio
• C. Optimized angle of attack
• D. Reduced engine power

Answer: (B)

In slow flight, the lift generated by the wings decreases as the aircraft approaches its stall speed. To maintain controlled flight at this low speed, the pilot must increase the angle of attack, which can lead to an increase in the induced drag component. The lift-to-drag ratio becomes less favorable as the increased angle of attack results in higher drag relative to lift. As the lift-to-drag ratio decreases, it indicates that for every unit of lift produced, more drag is experienced. This relationship is crucial because drag counteracts the forward thrust produced by the engines, making it more challenging to maintain speed and altitude. In summary, a decreased lift-drag ratio during slow flight results in increased drag, compelling pilots to be aware of their flight parameters and managing aircraft performance effectively.
