Flight dynamics is the study of the forces and motions that affect an aircraft during flight. It involves understanding how an aircraft responds to various inputs, such as control surfaces and environmental factors like wind. Key concepts include lift, drag, thrust, and weight, which together determine how an aircraft moves through the air. In flight dynamics, engineers and pilots analyze the stability and control of an aircraft. This ensures that it can be safely maneuvered during takeoff, cruising, and landing. Tools like flight simulators and mathematical models help in predicting how changes in design or conditions will impact the performance of the aircraft, such as those used in aerodynamics and aviation engineering.
