BS G 257-3:2004

This standard BS G 257-3:2004 Design of electromagnetic hazard protection of civil aircraft is classified in these ICS categories:

• 33.100.01 Electromagnetic compatibility in general
• 49.060 Aerospace electric equipment and systems

This part of BS G 257 is written to assist engineers working at all levels within companies involved in the aircraft industry to meet the applicable EMH requirements.

This part of BS G 257 is intended to assist engineers with planning the certification process and to ensure that the correct processes are applied to the writing of procedures and plans, and that the presently recognized methods of test are appropriately used.

The guide does not contain mandatory requirements, only guidance to assist in the solution of design problems.

The guide does not cover:

1. the protection of the airframe against the structurally damaging, direct effects of lightning;
2. the design of communication systems in order to produce interference free operation since it is felt that these aspects of RF systems design are covered in adequate detail in other documents e.g. Minimum Operational Performance Specification (MOPS). The problems of interaction between radio receivers and transmitters are still an important aspect of EMC problems;
3. electrostatic discharge.
