Static and dynamic longitudinal stability. Neutral point, static margin. Static directional stability. Static lateral stability. Factors affecting static lateral stability - dihedral and sweep angle of the wing. Dynamic directional-lateral stability - spiral divergence, stable and unstable Dutch roll motion.Dynamic stability modes and their influence on aircraft handling. Controllability and maneuvrability. Pitch (longitudinal) control, yaw (directional) control and roll (lateral) control. Trimming. Operating limitations. Aerodynamics of propeller.Flight mechanics of the basic regimes - straight horizontal steady flight, climb, descent and turns. Asymmetric thrust.

Rules for evaluation and completion of the course
The condition for granting the credit is 95 % physical participation in all forms of teaching. Furthermore, it is necessary to submit completed assignments within exercises and self-study. Obtaining credit is a condition of admission to the exam. The exam is written and then oral, while the focus of proving knowledge lies on a written exam, which can be taken in the form of a test. Classification according to the Study and Examination Regulations of the FME.
