Course detail

Communication, Navigation, Surveillance

FSI-OZLAcad. year: 2017/2018

The course incorporates communication, navigation and surveillance (CNS) principles and CNS equipment/aids. Relevant themes include explanation of radio facility function (ADF, VOR, DME, ILS and MLS), principles of primary and secondary radiolocation, area navigation (RNAV), ground support navigation systems, long range navigation principles (OMEGA, LORAN, DECCA) and future CNS systems vision. Mutual dependence of CNS technologies versus ATM procedures is highlighted. FANS, FEATS, ECAC, EATCHIP etc. concepts are also mentioned. Modern communication projects (ATN, VDL, CIDIN). Global navigation satellite systems. Automatized ATC systems. Airborne anti-collision systems.

Learning outcomes of the course unit

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.


High school level knowledge of mathematics and physics is demanded.

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 course-unit credit test comprises both common and detail questions related to the subject matter.
The examination is of written & oral form.
Classification fulfils ETCS rules.

Language of instruction


Work placements

Not applicable.


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. CNS/ATM mutual relationship will be stressed. Future trends will be mentioned in the necessary extend.

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

Lectures and exercises 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.
