In addition to Lift and Weight, there are two more forces that operate on the aircraft in opposite directions: Thrust and Drag. 🛩️ THRUST is the forward pulling force created by the propeller. If you were flying a jet, thrust would be provided by the jet engine's exhaust gases. In either case, thrust provides the forward movement that keeps airflow going over the wings. Opposing thrust is a force called DRAG. We can think of drag simply as the force that tries to hold the aircraft back by resis
