Lift Dynamic means how the upward force that helps an airplane stay in the air changes during flight. This force, called lift, depends on things like the speed of the airplane, the angle of the wings, the shape of the wings, and the thickness of the air. When any of these things change, the lift also changes. For example, when a plane goes faster or tilts its wings, it can create more or less lift. Understanding lift dynamic helps pilots control the plane better and keep it safe while flying.
