Summary

This paper discusses the static longitudinal stability of an aircraft in the simple case when the aerodynamic derivatives are independent of speed. An outline of the basic theory of static stability is given, accompanied by a working document, giving suitable forms for the estimation of neutral points from wind tunnel tests. A worked example is included for a typical case. No attempt is made to interpret the results, but the conclusions include a note on the C.G. margin. Loss of stability stick free, and scale effect are commented on briefly in the appendices.
