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 to obtain the course-unit credit: attendance at exercises (80% at the minimum), presentation of calculation tasks records or reports from laboratory exercises. The exam has written (the essential one) and oral parts. Evaluation fulfils the University requirements.

Language of instruction


Work placements

Not applicable.


The goal is to explain the basic flight mechanics of atmospheric aircraft. Familiarizing students with the method of assessment of classical theory of performance and a judgment of aerodynamic and propulsion characteristics efficiency on flight performance.

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

Lectures are optional. 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.
