Commentary: FAA Struggles to Keep Pace With Technology
Industry commentary suggests the FAA is struggling to adapt its certification processes to the rapid pace of technological change. While major OEMs are advocating for more streamlined, outcomes-focused certification, the agency maintains a cautious stance. This dynamic requires engineering teams to produce increasingly rigorous documentation and traceable evidence for new systems under standards like DO-178C and ARP4754A.
- The FAA's NextGen program, intended to shift from ground-based radar to satellite-based navigation, has faced significant delays and cost overruns. Launched in 2003, full implementation is now projected for at least 2030, with total government and industry costs estimated to reach $35 billion. - A key challenge in certifying artificial intelligence and machine learning systems is that existing standards like DO-178C were not designed for adaptive technologies whose behavior is defined by data. This makes traditional verification and validation methods difficult to apply, as it's not feasible to test for all possible inputs and learned behaviors. - In response to the 2020 Aircraft Certification, Safety, and Accountability Act, the FAA is delegating less responsibility to manufacturers and increasing its own oversight. This includes more detailed reviews of integrated systems and using independent expert groups for certification projects. - A recent bipartisan bill, the Aviation Innovation and Global Competitiveness Act, aims to streamline certification for new eVTOL and advanced air mobility aircraft. It would require the FAA to publish clearer timelines and expand the use of industry-developed consensus standards as acceptable means of compliance. - The Part 23 reform for small aircraft, effective in 2017, replaced prescriptive design requirements with performance-based standards. This was intended to reduce certification time and costs, and accelerate the adoption of new safety technologies by allowing manufacturers more flexibility in how they demonstrate compliance. - Traceability between system-level safety requirements (defined under ARP4754A) and high and low-level software requirements (managed under DO-178C) is a critical and complex challenge. Failures in this area are often cited as a primary source of defects in flight software. - The FAA's effort to modernize its infrastructure is hampered by aging equipment and funding challenges. About 40% of the FAA's core infrastructure is considered outdated, and the agency operates a dual system of legacy and modern technology, creating operational inconsistencies. - The FAA is creating new offices to better manage technological change, including an "Airspace Modernization Office" and an "Office for Advanced Aviation Technologies" to handle the integration of drones and advanced air mobility platforms.
