Learning Objectives to

The course material covers the intoductory topics refering to the local network technologies, describes the architecture of reference models OSI and TCP/IP, analyzes the prototypes MIL – STD – 1553 & ARINC which are implemented in the aircraft communication channels, compares the various means of data transmission emphasizing the aircraft optical fibre communications (fly by light), as well as introduces methodologies of analysis and composition of optical fibre networks. 

After successfully completing the course, students should be able to:

·                     identify and understand the basic techniques of aircraft local network design as well as the quality of the service provided.

·                     Understand the particularities and differences among the aircraft local networks.

·                     Name the basic elements of optical communications  (optical fibres, diodes, amplifiers, switches, etc.) and their applications in aircraft.

·                     Design an optical communication system (wired and/or wireless) and specify its efficiency

·                     carry out telecommunication network problem analysis and plan solutions, as well as evaluate comparatively alternative proposals.

·                     Work individually or collaborate with fellow students , in order to solve realistic problems with regard to aircraft networks.

·                     Use basic laboratory equipment to study the optical communication system efficiency.

General Skills

·                  Search, analysis and combination of data and information with the use of the necessary technologies

·                  Autonomous work

·                  Group work 

·                  Development of free, creative, critical thinking

TEACHING ORGANIZATION

STUDENT EVALUATION

For the theoretical part of the course, students sit for a written examination on the course material at the end of the  semester. 

Written examinations are carried out in Greek and include:

•    Short answer questions or multiple choice questions

•    Problem solving questions referring to optical network design and/or analysis

For the practical part, examinations are carried out during the laboratory sessions after the completion of the laboratory activities, in Greek, use of notes allowed, and include:

·                     Weekly simulation exercises  (35%)

·                     Laboratory measurements  (35%)

·                     Final test (30%) including short answer questions and problem solving questions relevant to lab activities or preparation and presentation of individual/group assignment.

Student attendance is considered sufficient if it covers 80% of the classes and students pass the examinations if they have succeesfully answered 2/3 of the simulation activities and the laboratory units.

Students who have sufficiently attended the lab sessions but have not achieved a pass grade, can re-participate in the final examination of the course. In that case, the grade of the practical part of the course is deternimed only by the grade of the final exam.
