Chapter 3. General requirements to avionics

3.2. Avionics requirements according to international standards EASA

One of the important approaches to safety is compliance with international standards of certification and aircraft operation. Adjusting of aviation infrastructure at the international level in the European region since 1970, has been engaged by Joint Aviation Authorities - JAA [79]. Activity of the JAA was to develop harmonized technical requirements (general aviation requirements, Joint Aviation Requirements 9 (JAR)) and Regulation of general technical standards (Joint Technical Standard Order - JTSO). Influence of JAA at the international level was applied to service, operation and licensing of aircraft. However, JAA lacked the authority, that would be released if only a single body with general standards in safety of flights existed, which should had been deprived of the national factors effect. Moreover, it was necessary to create a unified procedure for issuing certificates and permits, which would spread on the entire territory of Europe, and be released by a single body. In accordance to that, an international organization EASA was created in October 2003.

European Aviation Safety Organization (European Aviation Safety Agency - EASA) is responsible for creating of all the safety of flights rules, and ensures compliance of audits, related to these rules. In addition, EASA is responsible for coordinating research in the field of safety of flights, and for the monitoring of international aviation rules compliance by national administrations. [58]

EASA has developed a number of regulatory requirements (Certification Specifications - CS), to be met by PC hardware. CS requirements are directly related to the composition and functioning of avionics equipment on board of aircraft. In particular CS-25 certification includes requirements for the heavy aircraft [49]. Paragraph F of this document standardizes avionics equipment and covers basic compositional requirements, arrangement, construction, and structure and operation.
