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.
The aircraft is certified CS-23 by the European Aviation Safety Agency [2] and is being certified FAA FAR 23. [3] The aircraft was announced at the Paris Air Show 2015 in the form of 2 models. [4] The prototype was publicly unveiled during the 2017 edition of the airshow. [5]
The corresponding EASA Acceptable Means of Compliance AMC 25.1309 (included as a section of CS-25) does recognize ARP4754/ED–79. The FAA and EASA have both subsequently recognized ARP4754/ED–79 as valid for certification of other aircraft categories, and for specific systems such as avionic databuses.

EASA is responsible for new type certificates and other design-related airworthiness approvals for aircraft, engines, propellers and parts. EASA works with the EU member states' civil aviation authorities (CAAs) but has taken over many of their functions in the interest of aviation standardisation across the EU and in the non-EU member Turkey.

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]
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.
