ARP4761A

Safety does not rely upon magic numbers but rather real answers. Likewise, safety is never an accident, but true safety should prevent accidents. The numbers “4754” and “4761” are not magic but are associated with safety. Safety and the numbers have evolved – the new answers for safety are found in 4754A and 4761A; specifically, SAE’s ARP4754A and ARP4761A.

ARP4761A Guidelines

ARP4761A is rather more than a guideline for aircraft safety. ARP4761A (formally issued in 2018) is officially titled “Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment.”

In fact, ARP4761 is almost a tutorial on generalized safety and how to apply various theoretical analysis to assess ongoing development activities toward aircraft safety. Clearly, ARP4761A is tightly coupled with ARP4754A and lays the foundation for the most fundamental aspect of aircraft regulations: safety. Clearly, viewing the avionics development ecosystem, ARP4761A’s prominent place in the upper left conveys its importance:

The Safety Assessment Process

The safety assessment process is a vital aspect of aviation safety, and for avionics, ARP4761 provides the foundation.

Literally every aspect of aviation undergoes safety assessment to better understand potential risks, quantify them, and then prevent, detect, or mitigate them. Experienced aviation persons are truthful when stating the safety assessment process is perhaps the most important element of avionics development.

For avionics, the role of the safety assessment is to ensure the safety of the aircraft, its crew, and the occupants. Essentially, aircraft safety is optimized by performing careful analysis, architectural optimization, criticality level determination, component selection, architectural improvement, monitoring, and maintenance. Therefore, only by having a thorough safety assessment process can we ensure we have an architecture with additional safety-related requirements which address safety aspects.

The title of ARP4761 accurately justifies its importance within this fundamental process: “Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems & Equipment.”

The aerospace and aviation industry is experiencing innovative changes not seen for decades, where rapidly evolving technology has driven companies to develop disruptive products. The first commercial greater than 50-seat hybrid-electric aircraft is expected to make a fare-paying flight by 20321 and the FAA estimates over 545,000 commercial drones to be in use by 2021.2 Innovation brings increased complexity in the design process, including the connected networks that handle autonomous flight systems and unmanned, autonomous aircraft. The industry currently relies heavily on paper documents to track requirements— which simply can’t be depended upon in a digitized world with predominantly autonomous aircraft.   

The Chosen Solution for Leading Aircraft Companies

As the chosen requirements management platform for five of the leading global electric aircraft companies driving innovation, Jama Software recognizes and answers these challenges. The company has worked closely with its partners to provide an all-in-one solution to address and overcome these challenges with ease. Jama Connect for Airborne Systems helps engineering teams get set up quickly, allowing them to focus on product design and innovation, while reducing the costs and effort required to align their development processes to meet mission and safety-critical standards. 

“Aerospace systems engineering teams have a tough job: they are tasked with developing innovative, mission-critical systems at an accelerated pace and with unwavering quality standards,” said Keith Johnson, Chief Solution Officer at Jama Software. “Our new solution, designed specifically for these teams, will help facilitate the development process from start to finish. Jama Connect allows developers to hit the ground running with a purpose-built, out-of-the-box framework and best–practices guides that save critical time in the engineering process.”
