What is the glide ratio at an angle of attack of 8°?

• A. 6:1
• B. 10:1
• C. 12:1
• D. 15:1

Answer: (C)

The glide ratio represents the distance an aircraft can travel forward compared to the altitude lost during that flight. At an angle of attack of 8°, the aerodynamics of the aircraft typically allow it to maintain efficiency and stability in the air, leading to a glide ratio of 12:1. This glide ratio indicates that for every 12 units of horizontal distance the aircraft travels, it descends 1 unit vertically. An angle of attack of 8° strikes a balance between lift and drag, optimizing the aerodynamic performance for gliding. This allows the aircraft to cover more distance before losing significant altitude. The other glide ratios presented correspond to different angles of attack or conditions that do not provide as optimal lift-to-drag ratios at 8°. Evaluating glide performance involves understanding how the aircraft's design, weight, and environmental conditions influence its ability to glide efficiently.
