 of Aircraft systems. EUROCAE jointly issues the document as ED–79. The current version is ARP4754A and ED–79A, retitled as Guidelines For Development Of Civil Aircraft and Systems.

Objectives of the document

ARP4754 addresses primarily Avionics
Avionics
Avionics are electronic systems used on aircraft, artificial satellites and spacecraft.Avionic systems include communications, navigation, the display and management of multiple systems and the hundreds of systems that are fitted to aircraft to meet individual roles...

 and especially Avionics software
Avionics software
Avionics software is embedded software with legally mandated safety and reliability concerns used in avionics. The main difference between avionic software and conventional embedded software is that the development process is required by law and is optimized for safety.It is claimed that the...

It concerns itself with the whole life-cycle for systems that implement aircraft functions. The objective of this document is to provide guidance on the development of such systems in the certification context.

History

ARP4754 was defined in the context of aircraft certification

, in particular Part 25 Sections 1301 and 1309 of harmonized civil aviation
Civil aviation
Civil aviation is one of two major categories of flying, representing all non-military aviation, both private and commercial. Most of the countries in the world are members of the International Civil Aviation Organization and work together to establish common standards and recommended practices...

Fixed-wing aircraft
A fixed-wing aircraft is an aircraft capable of flight using wings that generate lift due to the vehicle's forward airspeed. Fixed-wing aircraft are distinct from rotary-wing aircraft in which wings rotate about a fixed mast and ornithopters in which lift is generated by flapping wings.A powered...

 certification standards. FAA Advisory Circular AC 25.1309-1A, System Design and Analysis, explains certification methodology for Part 25 Section 1309.

In May 1996, the FAA Aviation Rulemaking Advisory Committee (ARAC) was tasked with a review of harmonized FAR/JAR 25.1309, AC 1309-1A, and related documents, and to consider revision to AC 1309-1A incorporating recent practice and the impplications of new technology. This task was published in the Federal Register at 61 FR 26246-26247 (1996-05-24). The focus was to be on safety assessment and fault-tolerant critical systems.

In a parallel effort, SAE published ARP4754 in November 1996. In 2002 ARAC submitted to the FAA a draft Notice of Proposed Rulemaking (NPRM) and draft revision AC 1309-1B (the draft ARSENAL version) recognizing the role of ARP4754 in complex system certification. This draft remains unreleased, but ARP4754 became broadly recognized as an appropriate standard for aircraft system development and certification. 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.

ARP4754A and ED–79A were released by SAE and EUROCAE in December 2010. The document title has changed to Guidelines For Development Of Civil Aircraft and Systems.
