EASA CS-25 is the European Union Aviation Safety Agency Certification Specification for Large Aeroplanes. This certification procedure applies to large, turbine-powered aircraft, with max take-off weight more than 5,700kg (CS 25.1). It describes the minimum requirements that must be met for the certification of an aircraft in this class.
ARP4754(), Aerospace Recommended Practice (ARP) Guidelines for Development of Civil Aircraft and Systems, is a published standard from SAE International, dealing with the development processes which support certification of Aircraft systems, addressing "the complete aircraft development cycle, from systems requirements through systems verification."
In conjunction with ARP4754, ARP4761 is used to demonstrate compliance with 14 CFR 25.1309 in the U.S. Federal Aviation Administration (FAA) airworthiness regulations for transport category aircraft, and also harmonized international airworthiness regulations such as European Aviation Safety Agency (EASA) CS–25.1309.

Apart from this annex, there are also several certification specifications, including CS-25, for large aircraft, and CS-23, for medium and small aircraft. In application, airworthiness standards include a probability of loss of aircraft (PLOA) that is designed to be controllable (PLOAdc) as an overall attribute. [5]
Similar standards are maintained by other aviation authorities. For example European Technical Standard Orders (ETSO) by EASA for the European Union, [3] with limited reciprocal equivalence on a per-country basis. [4] These often have the same numbers as FAA TSOs. For example, the FAA TSO for aviation headsets is C139.

The European Aviation Safety Agency (EASA) was created in 2003 and reached full functionality in 2008, and has since taken over most of the JAA functions. JAA Certification Specifications, formerly known as JARs, are recognised by EASA as an acceptable basis for showing compliance with their national airworthiness codes.
