Lift = Weight for steady level flight. Drag is balanced by thrust for non-accelerating flight. Aerodynamic leverage - lift is 10-30 times bigger than drag! For 1 pound of thrust get 10-30 pounds of lift. Aerodynamic leverage - lift is 10-30 times bigger than drag! For 1 pound of thrust get 10-30 pounds of lift
