WebJun 15, 2024 · Thrust is the force that pushes a plane in a forward direction, and thrust opposes the force of drag. There are a couple of different ways a plane can generate the thrust needed to propel... WebThe propeller, coupled with the engine, is what produces enough thrust to move a plane forward. Once the plane is moving forward, the remaining four forces of flight combine to provide the necessary lift to get the aircraft in the air. These aerodynamic forces of flight, all working optimally together, result in an efficient and safe voyage.
