What is the drag coefficient of a plane?

Answer 1

The drag coefficient of a plane typically ranges from about 0.02 to 0.07, depending on its design and aerodynamic characteristics. Factors such as wing shape, fuselage design, and surface smoothness influence this coefficient. A lower drag coefficient indicates more efficient aerodynamics, which is crucial for fuel efficiency and performance. Different aircraft types, from gliders to commercial airliners, will have varying drag coefficients based on their intended use and design features.
