The present article depicts the process followed in order to obtain the Drag Polar for an Agricultural Aircraft designed and manufactured in Colombia. The work consisted in the determination of a generalized-power curve (PIW-VIW Method) through data gathering during flight tests at different altitudes and airspeeds. The obtained results are given in the form of aerodynamic parameters, being the most relevant: the Zero-Lift Parasite drag coefficient (CDo) and the Oswald efficiency factor (e).
