A fixed pitch propeller driven aircraft, Cessna Skyhawk 172P, cruises at sea level at 110 kts, and 75% engine brake power. The engine of Cessna 172P, which is 4-cylinder Lycoming 0-320-D2J piston engine, produces 160 BHP at maximum throttle. Takeoff Gross Weight, Wo Wing Area, Sref Aspect Ratio, AR Taper Ratio, A Using these information, answer the followings. Cessna Skyhawk 172P 1110 [kg] 16.2 [m] 7.5 0.67 a) Determine the Lift-to-Drag ratio (L/D) ratio of the aircraft for the given cruise condition. Assume cruising weight is the same as takeoff gross weight. (Note that the aircraft does not necessarily fly at maximum range conditions.) b) Determine CDo of the aircraft. c) Assuming the weight of the aircraft remains constant, determine (L/D) max and corresponding velocity at sea level
