Learning outcomes of the course unit

Students will gain basic knowledge and experience of flow of air around the aircraft. The knowledge is necessary to be successful at pilot training.

Prerequisites

Basic knowledge of mathematics, algebra, differential and integral calculus.
Basic knowledge of physics, Newton's laws.
Basic knowledge of mechanics, statics and dynamics.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Participation at seminars and lectures is obligatory. A course-unit credit awarding is conditioned with the attendance at all lessons (must be higher than 20 of 26 lessons). Examination is written and oral. Written part comprises solving a problem, in the oral students answers to 6 questions they have randomly choosen. Final evaluation is calculated as the average value of all 7 results, unless one of them is failed. If one result of 7 is failed final evaluation is failed.

Aims

Pilot-students will learn basic theories of flying. They have to understand the origin and value of lift and drag force actiing on the wing and the aeroplane. They will understand basic physical laws applied to flying.

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

Students have to be present at 10 of 13 seminars at least. They have to solve all problems dealt with at missed seminars. If student miss more than 50 % of seminars, individual compensation is required.
