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
Course-unit credit requirements: participation in the course (80% at the minimum), all elaborated tasks must be hand in on time. The exam is of oral form – three questions and if necessary a lecturer asks one additional question.
Language of instruction
The objective of the course is to make students familiar with aircraft design method with predetermined parameters. Design optimisation regarding the weight and operating costs.
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.
