Consider an airplane patterned after the Beechcraft BonanzaV-tailed, single-engine light private airplane. The characteristicsof the airplane are as follows: aspect ratio = 6.2, wing area = 181ft2, Oswald efficiency factor = 0.91, weight = 3500 lb,and zero-lift drag coefficient = 0.027. The airplane is powered bya single piston engine of 345 hp maximum at sea level. Assume thepower of the engine is proportional to free-stream density. Thetwo-blade propeller has an efficiency of 0.83. Estimate thesea-level liftoff distance for the airplane. Assume a paved runwayand CL,max = 1.1 during the ground roll. Whenthe airplane is on the ground, the wings are 4 ft above theground.
