Analysis of modern requirements for the development of aircraft air conditioning system

The article presents a study of modern requirements for the development of air conditioning systems (ACS) of transport category civil aircraft in the context of their updating and harmonization with international best practices in the field of aircraft design and certification. It has been established that the competitiveness of an aircraft directly correlates with the completeness and detail of airworthiness standards (AS), which, in turn, has a significant impact on flight safety and operational efficiency of aircraft. Consideration is given to the recommendations from the International Civil Aviation Organization (ICAO) regarding the development of national AS and ensuring their uniformity among states-developers of aircraft, and to ICAO recommendations for the ACS development. Advanced practices by the Federal Aviation Administration (FAA), the European Aviation Safety Agency (EASA) in the field of continuous systemic updating and harmonization of AS have been reviewed and summarized. The key factors: aircraft certification procedures, interaction between aviation authorities and development enterprises, international bilateral agreements on flight safety (BASA) – all of which together determine the uniformity of foreign certification systems to ensure a high level of flight safety and efficient operation of aircraft – have been formulated and described. A comparative analysis of the Russian Federation, the EU, the USA national AS has been performed: AP 25 and Airworthiness Norms 25 by Rosaviatsia, CS 25, Part 25, respectively, to the aircraft ACS. Similarities and differences in the requirements between the Russian Federation, the USA, and the EU have been identified along with an assessment of uniformity levels between domestic and foreign AS related to the aircraft ACS. Conceptual proposals for updating and supplementing the AS for increasing operational and technical characteristics of this functional aircraft system have been formulated.
