The angle of attack that provides the most lift for the least amount of drag is approximately:

• A. 6°
• B. 12.4°
• C. 8.5°
• D. 20°

Answer: (A)

The angle of attack that provides the most lift for the least amount of drag is known as the "optimal angle of attack." This angle allows the aircraft to generate maximum lift while minimizing induced drag, which is a crucial aspect of efficient flight. At lower angles of attack, lift begins to increase with an increase in angle; however, drag also increases but at a slower rate compared to lift. As the angle of attack approaches this optimal point, lift continues to increase while drag starts to increase more substantially. The key is to identify the angle where this balance is ideal, maximizing lift-to-drag ratio. Typically, the optimal angle of attack for most aircraft lies within the range of 6° to 12°. Since 6° often represents a more conservative and commonly recognized estimate for general aviation planes in cruise conditions, it is the most appropriate selection in this context. This understanding helps pilots achieve the best efficiency during flight phases like climb and cruise, making decision-making based on this optimal angle very important for maintaining good performance.
