Course detail
Principles of Flight II
FSI-OZ2 Acad. year: 2022/2023 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.

Learning outcomes of the course unit
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.
Prerequisites
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.
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
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.
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.
Specification of controlled education, way of implementation and compensation for absences
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.
