"WebThrust, drag, lift, and weight are forces that act upon all aircraft in flight. Understanding how these forces work and knowing how to control them with the use of power and flight controls are essential to flight. The four forces acting on an aircraft in straight-and-level, unaccelerated flight are thrust, drag, lift, and weight. " - How is lift generated in a helicopter
