Learning outcomes of the course unit

Students will acquire knowledge and basic experience in airplane electric systems engines, protection and detection systems, aircraft system. Furthermore, in the field of construction of helicopters, rotor heads, and control systems. This knowledge is necessary to successfully pass theoretical examinations for subsequent pilot training.

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

Obtaining the credit is conditioned by 80% participation in the exercises and successful passing the final test. The exam is written and oral. The written part presents the theoretical part and examples from the content of DLT, CKS and DKS. The oral part of the exam is an evaluation of the written part and a discussion.

Language of instruction


Work placements

Not applicable.


The aim of the course is to provide students with knowledge about aircraft systems so that they understand their function in terms of characteristics, reliability and safety of flight operations. Furthermore, basic information on the problems of helicopter design and systems.

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

If presence at lectures is less then 80%, students have to prove elaborated tasks and completed parts from missed lessons. Missed lessons can be compensated in a very limited extend by consultations with the lecturer.
