The index of perfection of the system is offered a “airframe - power-plant - aviation munitions” for an attack aircraft. The theoretical analysis of influence of mass, geometrical and aerodynamic descriptions of aviation munitions is conducted, characteristics of engine of power-plant of airplane on his tactical flight characteristics. Researches of two flight cycles of airplane are conducted with different engines and the preliminary results of his tactical flight and operational characteristics are got with munitions and without them. The developed index allows to conduct the ground of directions modernization of the system a “airframe - power-plant - aviation munitions”.
