WG-63
System Engineering

Complex Aircraft Systems

WG-63 is concerned with aircraft, systems and equipment having safety implications, throughout aircraft life cycle. The WG-63 objective is to provide industry with guidelines relating to the safety of aircraft, systems and equipment both as part of development and in-service continued airworthiness. To this end, the working group will publish specific standards reflecting industrial practices that relate to the safety aspects of development and certification and continued airworthiness of aircraft systems, and their in-service continued airworthiness. Currently, WG-63 is engaged (or has undertaken to engage) in the joint development of the following safety related guidelines: – Guidelines and methods for conducting the safety and assessment process on civil airborne systems and equipment (ED-135/SAE ARP 4761A) – Development of Atmospheric Neutron Single Event Effects Analysis for Use in Safety Assessments (ER-008/SAE AIR6219) – Guidelines for Development of Civil Aircraft and Systems (ED-79B/ARP4754B) The work is carried out jointly with SAE S-18.
