Chapman-Enskog method is a base of the transport properties calculation of partially ionized gases. This method represents the transport coefficients as functions of the collision integrals. These collision integrals are required for each pair of species of a partially ionized gas and different method can be used for their calculation. In the first part of the paper the calculation method of the transport properties (electrical conductivity, thermal conductivity, viscosity) is briefly described. The transport coefficients values of air (Ar, N, O, e−) for temperatures 1 000 ≤ T ≤ 20 000 K and the influence of the choice method of the collision integral calculation on results are presented in the second part of the paper.
