EMC design of an aeronautical system (module 1)

Goals

The objectives of the training EMC design of an aeronautical system (module 1) :

At the end of this training course, trainees will be able to anticipate EMC, lightning and HIRF constraints in an aircraft with the aim of coherently integrating electromagnetic protection and validating it during the aircraft certification cycle.

The aim of this training course is to:

• Understand the aeronautical certification process


• Gain an overview of the specific features of aeronautical standards


• Understand the phenomena of coupling, lightning and HIRF in an aircraft in order to optimise electromagnetic protection

Program

1- Introduction
• The evolution of EMC in aeronautics
• V-cycle


2- Certification process
• Certification specifications (CS-23/25/27/29)

- CS-25 (25.581; 25.899; 25.1309; 25.1316; 25.1357); CS-23; CS-27; CS-29
- EWIS

• Means of compliance (AMC, AC, MoC)
• Applicable standards
- ED-14/DO160; ED-84: ED-107; ED-239; ED-248; ED-234.
- SAE ARP5412; SAE ARP5583; SAE ARP60493; 
- ABD0100 1.2
- D6 16050
• The criticality of systems with regard to flight safety
• Maintenance


3-Coupling on aircraft and impact on equipment
• Lightning and high-field environments (HIRF)
• Coupling phenomena on aircraft (EMH, lightning, ESD, EMC, crosstalk, etc.)
• Risks related to PEDs and radio/navigation and communication systems (non-interference and interoperability)
• Risks related to cosmic radiation.
• Test environments (DO160 sections 16 to 25)
• Equipment design and protection to comply with tests


4-Methods of protecting wired access and equipment enclosures
• Electromagnetic protection of systems (installation rules, shielding, raceway)
• Equipment protection to comply with tests
• Specific features of ARINC, 1553, AFDX, CAN and TOR links with regard to electromagnetic threats


5-Response to certification for CS-25
• Equipment manufacturer's compliance responses to the aircraft manufacturer's process
• Analysis of electromagnetic specifications
• Development of the Electromagnetic Protection Plan
• Qualification Plan and Test Procedures
• Summary of results and Design Performance Statement
• Aircraft manufacturer's responses to authorities
• Certification plan
• System-level and aircraft-level testing (lightning and strong field transfer function)
• EMC certification summary
