What is BS EN 4559-6:2017?

BS EN 4559-6:2017 is a technical standard that provides guidelines for the evaluation and testing of the performance of aviation systems. It focuses specifically on the determination of electromagnetic compatibility (EMC) for aircraft equipment and subsystems. This standard helps to ensure that aviation systems do not interfere with each other, thereby ensuring safety and reliability in aircraft operations.

Importance of Electromagnetic Compatibility in Aviation Systems

Electromagnetic compatibility plays a crucial role in the design, development, and certification of aviation systems. With the increasing complexity of aircraft systems and the integration of advanced technologies, there is a higher risk of electromagnetic interference (EMI) that can adversely affect the operation of onboard equipment.

Ensuring the electromagnetic compatibility of aviation systems is important to prevent interference between different equipment and subsystems. For example, if a communication system interferes with the navigation or control systems, it can lead to potential accidents or malfunctions. By complying with BS EN 4559-6:2017, manufacturers can mitigate these risks and meet the required levels of electromagnetic compatibility.

Evaluating Electromagnetic Compatibility

BS EN 4559-6:2017 provides a comprehensive framework for evaluating electromagnetic compatibility. It outlines the necessary test procedures and measurement techniques to assess the level of EMI generated by aircraft equipment and subsystems. The standard defines acceptable limits for emissions and susceptibility, ensuring equipment operates reliably in the intended electromagnetic environment.

This evaluation process typically involves subjecting the equipment to various tests such as radiated emissions, conducted emissions, radiated immunity, and conducted immunity. These tests simulate realistic scenarios to determine how well the equipment can perform without generating excessive interference or being affected by external interference.

Benefits of Compliance

Complying with BS EN 4559-6:2017 offers several benefits, not only for manufacturers but also for airlines and passengers:

Ensures safety and reliability: Meeting the requirements of this standard helps to ensure that aviation systems operate safely and reliably. It reduces the risk of equipment malfunction or interference that can compromise the aircraft's performance.

Enhances interoperability: By complying with these guidelines, equipment from different manufacturers can work together seamlessly, without causing compatibility issues.

Streamlines certification process: Compliance with international standards enables easier certification of aviation systems. Manufacturers can demonstrate that their products meet the necessary requirements, reducing the time and effort required for certification.

In conclusion, BS EN 4559-6:2017 provides essential guidelines for evaluating and testing the electromagnetic compatibility of aviation systems. Compliance with this standard ensures safe and reliable operation of aircraft equipment, mitigates the risks of interference, and simplifies the certification process. By adhering to these guidelines, manufacturers contribute to the overall safety and efficiency of aviation systems in an increasingly technology-driven industry.
