This paper discusses a static stability theory for airplanes. The conventional definitions of static stability are neither clear nor systematic. On the basis of these situations, in the first report of this paper, a system of definitions on 6 static stability concepts was proposed, and two concepts of static flight-velocity stability and static angle of attack stability were studied. And in the second report, a concept of static pitch stability was discussed. This third report discusses on the three static stability concepts in sideslip, roll and yaw, and proposes that “dY/dβ<0, ” “dR/dΦ<0” and “dN/dΨ<0” should be used as the fundamental definitions, where R means rolling moment. The general criteria for these static stabilities are deduced from these definitions. From these criteria, “CYβ<0, ” “Clβ/CYβ>0” and “Cnβ>0” are obtained as the stable conditions. Finally, this report represents the whole summary of this paper.
