Entry knowledge

High school level knowledge of mathematics and physics is demanded.

Rules for evaluation and completion of the course

Conditions for obtaining the course-unit credit: 80% participation at the lectures and excercises and the minimum  50% evaluation of the final written test at least. Succesful result of the course-unit credit test is the basic condition to attend the oral examination. Classification of the exam is predetermined by the BUT university requirements.


Lectures (min. 80% attendance required) and exercises (100% attendance required) are realized by means of audio-visual method and therefore student´s presence is necessary.
Missed lectures & exercises can be compensated in a very limited extend only by personal consultations with the lecturer or by a selfstudy under the lecturer´s personal supervision.

Aims

Students will be acquainted with the whole spectrum of nowadays CNS radionavigation aids being in use of commercial air carriers. They will be familiarized with relevant current and future CNS technologies used for ATC/ATM. CNS/ATM mutual relationship will be stressed. Future development trends will be mentioned in the necessary extend.


The subject will allow students to get acquainted with the CNS/ATM technologies as well as with main procedures used in civil air traffic. Students will comprehend the relationship between both an aircraft and ATS and get the common philosophy of automated CNS/ATM systems as well.
