STG’s Impact on Industry Regulation
The aerospace industry continues to evolve, so regulation must also move quicky to maintain optimal safety. Dr Sean O’Kell, our Business Unit Director, works with the STG team to help shape the regulations that define how new technologies integrate seamlessly into operations, ensuring both performance excellence and passenger safety.
In their work, Sean and the STG team draw from decades of combined experience, blending the best practices of fixed-wing aircraft and helicopters, to create standards that address the unique challenges posed by current developments such as eVTOL (electric vertical takeoff and landing) aircraft.
We recently spoke to Sean about the team’s knowledge and expertise in the wider industry, including regulatory changes and updates on eVTOL.
Sean, what is your role in aerospace regulation?
I oversee certification activities for all STG products and, over time, this has given me a significant insight into testing. Since the early 2000s, I’ve actively participated in SAE Aerospace Standards Committee meetings focused on Interior Lighting, a role that has positioned me to help shape industry guidelines for aerospace emergency lighting.
One of my key responsibilities is overseeing the development of the SAE Aerospace Recommended Practice 503, currently moving to Revision H. While that title may sound highly technical, it plays a vital role in ensuring that safety guidelines keep pace with the latest technological advances. The STG team’s efforts to incorporate new materials, such as photoluminescent technologies, are a prime example of how we are working to future-proof aviation safety.
Beyond technical writing, our team engages with regulatory bodies such as the FAA and EASA, to ensure that new technologies are not only functional, they are also compliant with global safety standards. STG’s work influences critical standards impacting both cabin safety and flight deck operations, guiding the industry toward safer and more efficient air travel—not only for manufacturers but for the entire aerospace community.
The work we do with industry authorities allows us to gain significant insights into the sector and we use this learning to shape future innovations. It means we always have a finger on the pulse.
Does STG have any specialist areas?
I, with the help of the team, am responsible for all aspects of STG’s photoluminescent products worldwide. Photoluminescent materials offer a significant advantage in emergency lighting systems because they are lightweight and consume no electrical power. As leaders in this part of the business, we have the expertise to offer valuable insights to other players in the market. Our photoluminescent range has been built with this expertise as a foundation.
What are the key trends right now and how do you stay up to date?
As eVTOL aircraft technology advances, its presence in the media grows as well. While manufacturers remain optimistic about swift deployment, a more realistic timeline suggests it will take longer than anticipated, with potential challenges and setbacks for some companies along the way. The journey ahead is extensive, particularly given the time required to establish regulatory frameworks for emerging innovations. However, this process is essential for creating a solid foundation for the safety standards of future products.
We are honoured to have been selected to develop the first working SAE standard for eVTOL cabin emergency lighting, ensuring these new aircraft adhere to the same rigorous protocols as conventional aviation models.
Alongside other members of the committee, I stay up to date with technological advancements and industry regulations to update these documents every five years. For example, the most recent revision included the introduction of photoluminescent materials, which involved collaboration with global industry experts, including specialists from OEMs and key suppliers to address both cabin and flight deck requirements. These revisions ultimately influence FAA regulations, providing the highest standards of passenger safety.
By staying ahead of technological trends and rigorously applying our expertise, we ensure that both current and next-generation aircraft meet the highest standards. Find out more about our approvals here.
