This is a five days course covering the important features of the ILS fundamentals. The student will work through a number of training exercises from the theory manual and a number of selected practical cases. The course is designed for those who have been working within the aeronautical services for some time, having a reasonable knowledge in radio technical systems. After this course the student will have a good understanding of how the ILS works, and is ready to receive the On-the-Job training required to perform independent preventive maintenance work on ILS systems.

The ILS Fundamentals course is based on EU Regulation 2017/373 minimum requirements, and covers three out of five taxonomy levels. This is how the regulation describes the three levels of knowledge and understanding, all of them covered in the course:

Level 1 — Basic knowledge of the subject. It is the ability to remember essential points, to memorise data, and retrieve it.

Level 2 — The ability to understand and to discuss the subject matter intelligently in order to represent and act upon certain objects and events.

Level 3 — Thorough knowledge of the subject and the ability to apply it with accuracy. The ability to make use of the repertoire of knowledge to develop plans and activate them.

Level 4 and 5 is covered in the Advanced ILS course.
