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.

Co-requisites

Not applicable.

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

Conditions for obtaining the course-unit credit: participation in the course (95% at the minimum), presentation of calculation tasks records. The credit is necessary to be admitted to examinations. The exam has written form (the essential one) and oral parts. The evaluation process fulfills the University requirements.

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.
