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. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Conditions for awarding the course-unit credit: 80% participation in practical exercises, submission of completed computational and laboratory exercises and protocols. The credit is necessary for registering for the examination. The exam I consists of written (the essential one) and oral parts.
Language of instruction
Czech
Aims
The goal is to make students acquainted with the organization and preparation of in-flight tests of atmospheric aircraft. Organization of strength tests. Distribution of loading and design test equipment and test program. Learning theory, experience, measurement.
Specification of controlled education, way of implementation and compensation for absences
Exercises are compulsory. It is possible to compensate missed exercises (in justified cases) by elaborating of a substitute assignment.
