In normal flight, a light aircraft derives its forward motion from the thrust provided by the engine-driven propeller. If the aircraft is maintaining a constant height, direction and speed then the thrust force will balance the air's resistance to the aircraft's motion through it. The forward motion creates airflow past the wings and the dynamic pressure changes within this airflow create an upward-acting force or lift, which will balance the force due to gravity — weight —...
