Entry knowledge
The basics of mathematics – differential and integral calculus, common differential equations. The basics of common mechanics – force effect on a body, kinematics and dynamics. The basics of fluid mechanics.
Rules for evaluation and completion of the course
The course ends with a classified credit. The condition for granting a classified credit is 95 % physical participation in all forms of teaching. Furthermore, it is necessary to submit completed assignments within exercises and self-study. Demonstration of knowledge takes place in the form of a test. Classification according to the Study and Examination Regulations of the FME.
Lectures and seminars are compulsory, and attendance is checked and recorded. The absence (15%-20%) can be compensated by personal consultation with the lecturer and elaboration of individually assigned topics and exercises. All tasks must be finished and handed in the credit week at the latest.
Aims
The goal is to familiarize students with the basic aerodynamics of atmospheric aircraft, the principle of forces and moments emergence on aircraft. Students will learn to apply practically their knowledge of aerodynamics in pilot practice for the purpose of higher flight safety.
The students gain basic knowledge and habits for the aerodynamic application usable for flying from the piloting point of view. They acquire knowledge of flying theory necessary for effective and safe aircraft traffic.
