FSI-OZ2Acad. year: 2018/2019

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 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.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Conditions for obtaining the course-unit credit: participation in the course (80% at the minimum), presentation of calculation tasks records. The credit is necessary to be admitted to examinations. The exam has written form (the essential one) and oral parts. Evaluation process fulfils the University requirements.

Language of instruction


Work placements

Not applicable.


The goal is to familiarize students with basic problems of flying characteristics of an atmospheric aircraft, flight stability and controllability. Students will learn to judge the influence of operating parameters and flight conditions on aircraft flying characteristics.

Specification of controlled education, way of implementation and compensation for absences

Lectures and seminars are compulsory, and the attendance (80% at the minimum) is checked and recorded. The absence (in justifiable cases) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. Individual tasks must be finished and handed in the week credits are awarded at the latest.
