Cl<sub>lift</sub> is generally derived from a 2D table as a function of AoA. In the real world it is also a function of Reynolds Number. | ||
* '''Drag: CD''' It is important to ensure all coefficient functions in the drag section remain positive. When drag coefficient functions are negative, drag is effectively acting as thrust opposite the relative wind. | * '''Drag: CD''' It is important to ensure all coefficient functions in the drag section remain positive.
