An intensive overview of helicopter equations of motion, static stability characteristics, and engine failure characteristics. Subjects include an introduction to mathematical analysis techniques, theory and flight test procedures to evaluate helicopter static stability characteristics, and engine failure characteristics evaluation procedures. Also included is a brief introduction to mechanical flight control systems and closed loop handling qualities.
