How to Evaluate Equivalent Parasite Drag Area?

Equivalent Parasite Drag Area evaluator uses Flat Plate Area = Form Factor Drag*Skin Friction Coefficient*Aircraft Wetted Area to evaluate the Flat Plate Area, Equivalent Parasite Drag Area is a concept used in aerodynamics to represent the total drag of an aircraft due to non-lifting components such as the fuselage, wings, tail surfaces, and any other protruding features. It's called "equivalent" because it's a hypothetical area that, if exposed to the airstream, would produce the same amount of drag as the entire aircraft. Flat Plate Area is denoted by A symbol.

How to evaluate Equivalent Parasite Drag Area using this online evaluator? To use this online evaluator for Equivalent Parasite Drag Area, enter Form Factor Drag (Φ_f), Skin Friction Coefficient (μ_f) & Aircraft Wetted Area (S_wet) and hit the calculate button.
