BS G 257-1:1998

What is BS G 257-1 - Design of electromagnetic hazard protection of civil aircraft about? 

BS G 257-1 discusses civil aircrafts.  BS G 257-1 has been written to assist engineers working at all levels within companies involved in the aircraft industry. The guide does not contain mandatory requirements, but rather advice to assist in the solution of design problems. In order to meet the EMH protection needs of the customer's specification, it is strongly recommended that engineers consider the features discussed and use the suggestions made or provide an alternative solution for any problem.

This guide does not discuss the following:

• The protection of the airframe against the structurally damaging, direct effects of lightning
• The design of communication systems in order to produce interference-free operation, since these aspects of RF systems design are covered in adequate detail in other documents; however, the problems of interaction between radio receivers and transmitters remain an important class of electromagnetic compatibility (EMC) problem.

Who is BS G 257-1 - Design of electromagnetic hazard protection of civil aircraft for? 

BS G 257-1 on the design of electromagnetic hazard protection of civil aircraft is useful for: 

• Design engineers
• Aircraft manufacturers
• Aerospace electric equipment and systems manufacturers
• Electrical engineers
• Quality control and regulatory authorities

Why should you use BS G 257-1 - Design of electromagnetic hazard protection of civil aircraft?

The design of EMH protection for an electronic system should aim to ensure that the EM

environment in which the system is immersed does not affect the normal operation of the system. In addition, the design should reduce the emissions of conducted or radiated EM energy from the system to a level that will not upset or damage the normal operation of other systems. Thus, the overall target of EMH protection should be to achieve EMC.

BS G 257-1 provides an understanding of the basic principles of EMH protection design. This can help to assist in the solution of design problems so that electronic equipment does not affect flight operation.
