SupplementaryNotes 16. Abstract Design procedures and supporting data necessary for configuring light aircraft to obtain desired responsesto pilot commands and gusts are presented. The procedures employ specializations of modern military and jet .transport practice where these provide an improvement over earlier practice. General criteria for riding and handling qualities are discussed in terms of the airframe dynamics. Methods available in the literature for calculating the coefficients required for a linearized analysis of the airframe dynamics are reviewed in detail. The review also treats the relation of spin and stallto airframe geometry.
