CS-25 Basic, Initial Training (Module 1) – refer to D-010


The aim of this course is to introduce the EASA Certification Specifications in theory and as well with a practical approach on Avionics Systems.

Objectives of the course:

The objective of this course is to to educate and train participants about the key elements to consider in relation to EASA CS-25 for the modification or installation of avionics systems in Large Aircraft, e.g. Flight Management System (FMS).

The course aims to fulfil the following pedagogical objectives:

  • to educate and train the candidate about the key elements to consider in CS-25 for the avionics system installation / modification in Large aircrafts (example: Flight Management System – FMS).
  • to enable the candidate to justify and select specific CS-25 requirements to qualify and meet the compliance for avionics system .
  • explain the safety implication and the functional requirements on avionics system to be able to comply with the CS-25 safety objectives.
  • train the candidates to understand the importance of lightning effect, HIRF, EMI, and system testing to adhere to CS-25 requirements and associated MOCs.
Key Topics of the course:
  • understanding of CS-25 in respect to avionics system, and considering the requirements for system installation/modification in large aircrafts, AMC/GM.
  • how to be selective in CS-25 requirements for avionics system without compromising safety objectives.
  • focus on the safety aspects of CS-25 in terms of avionics system and its protection against fire, smoke, lightning, HIRF & EMI.
  • discussion on subjective topics relates to commonly installed avionics system.

General Practices in the avionics system installation/modification & design consideration for the showing of compliance to CS-25.

Regulatory Basis of the course:
  • EASA, Certification Specifications and Acceptable Means of Compliance for Large Aeroplanes CS-25, latest amendment.
  • EASA AMC 25.1309 System Design Safety and Analysis.
  • FAA AC 25-16, Electrical Fault and Fire Prevention and Protection.
