Course detail
Principles of Flight II
FSI-OZ2 Acad. year: 2024/2025 Summer semester
Static and dynamic longitudinal stability. Neutral point, static margin. Static directional stability. Static lateral stability. Factors affecting static lateral stability – dihedral and sweep angle of the wing. Dynamic directional-lateral stability – spiral divergence, stable and unstable Dutch roll motion.
Dynamic stability modes and their influence on aircraft handling. Controllability and maneuvrability. Pitch (longitudinal) control, yaw (directional) control and roll (lateral) control. Trimming. Operating limitations. Aerodynamics of propeller.
Flight mechanics of the basic regimes – straight horizontal steady flight, climb, descent and turns. Asymmetric thrust.

Entry knowledge
The basics of mathematics – differential and integral calculus, common differential equations. The basics of common mechanics – force effect on a body, kinematics, dynamics. The basics of aerodynamics.
Rules for evaluation and completion of the course
The condition for granting the credit is 95 % physical participation in all forms of teaching. Furthermore, it is necessary to submit completed assignments within exercises and self-study. Obtaining credit is a condition of admission to the exam. The exam is written and then oral, while the focus of proving knowledge lies on a written exam, which can be taken in the form of a test. Classification according to the Study and Examination Regulations of the FME.
Lectures and seminars are compulsory, and the attendance (95% 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 credits week at the latest.
Aims
The goal is to familiarize students with basic problems of flying characteristics of an atmospheric aircraft, flight stability, and controllability. Students will learn to judge the influence of operating parameters and flight conditions on aircraft flying characteristics.
Familiarizing with basic criteria for evaluating flying characteristics of an atmospheric aircraft. Qualitative and quantitative considering of flight performance and dynamic behavior regarding piloting and optimal use of aircraft during flying activity.
