Page 3 of 10 Coefficient of lift at 10,000 ft The Boeing 737-300 produces a lift coefficient of .43 at 10,000 feet at maximum takeoff weight. W= 124,500 lbs V = 320 knots S = 1135 Ft² C_L = ____295 * W____ 7385 * 320² * 1135 C_L = 295 * 124,500 .7385 * 320² * 1135 C_L = 36727500 85831424 C_L = .43 4. C_L MAX C_L MAX is computed at the maximum landing weight, 114,000 lbs, at sea level.
