Syllabus of lectures:

1. Basic concepts of stability and control, static longitudinal stability - acting forces, position of aerodynamic centre.

2. Static longitudinal stability, wing moment line, contribution of horizontal tail surfaces (VOP) to the airplane's pitching moment.

3. Longitudinal dynamic stability, neutral point.

4. Static and dynamic directional/lateral stability, effect of wing lift, vertical tail surfaces (SOP), effect of wing sweep.

5. Control - general, longitudinal controllability and manoeuvrability of the aircraft, centre of gravity position, methods of influencing control forces, balance.

6. Directional/lateral control and manoeuvrability, influence of control forces, rudder mass balance, spiral divergence.

7. Speed of sound - effect of temperature and altitude, Mach number, compressibility.

8. Subsonic flow, Prandtl-Glauert rule and its application.

9. Shock waves, effects on aerodynamic characteristics, effects of geometry.

10. Critical Mach number, control effectiveness, means to influence critical Mach number.

11. Specifics of supersonic aircraft, aerodynamic heating, buffeting.

12. Operational limitations, aeroelastic phenomena, flutter, manoeuvring envelope, gust envelope, aileron reversion.

13. Propeller - stresses, secondary effects of propeller, gyroscopic moments, asymmetric thrust

14. Repetition, reserve
