What is BS G 257-2 - EMH protection in civil aircraft about?
BS G 257-2 is a standard that covers EMH protection in civil aircraft, ensuring the safety, risk reduction and prevention of hazards in aerospace applications.
BS G 257-2 provides guidance on the design features of airframes and system installations necessary to achieve an acceptable level of EMH protection in a hostile EM environment.
Who is BS G 257-2 - EMH protection in civil aircraft for?
BS G 257-2 on EMH protection in civil aircraft applies to:
- Aeronautical engineers and designers
- Electrical engineers
- Manufacturers of aircraft
- Safety assurance services
- Testing houses for aircraft
- Regulatory bodies
Why should you use BS G 257-2 - EMH protection in civil aircraft?
Details of the airframe design can have major impacts on the implications of EMHs on safety or on the cost of ownership. The material choice affects screening performance and different materials also behave quite differently when a lightning arc attaches.
BS G 257-2 provides users guidance on the design of the airframe, including metallic airframe materials, non-metallic airframe materials, bonding measures, additional metals, non-fuel zones, and fuel zones, ensuring the structural integrity and stability of the airframes.
BS G 257-2 provides users guidance on the design of the system installation, including system installation in non-fuelled areas of the airframe and system installation in fuelled areas of the airframe, ensuring the safety of electrical systems and prevention of electrical failures.
With obedience and compliance to BS G 257-2, users can develop and plan a framework for electrical systems to ensure safety, resilience and durability in aerospace applications.
