Eamonn Brennan joins Vertical Aerospace as advisor to its Board, strengthening company’s regulatory expertise
Vertical Aerospace has appointed Eamonn Brennan as an adviser to its Board, strengthening the company’s regulatory expertise as it progresses towards certification.
Brennan has been a central figure in European aviation for many years, including serving as Director General of Eurocontrol, the organisation responsible for coordinating and managing air traffic control across Europe, from 2018 to 2022. He was also Chief Executive of the Irish Aviation Authority (IAA), the civil aviation regulator for Ireland, from 2003 to 2017.
Brennan joins as the company recently completed piloted thrustborne testing for its VX4 prototype and continues working with the CAA to expand its flight envelope ahead of wingborne flight.
Commenting on his new role, he said: “Vertical is redefining how the world moves, but certifying a novel aircraft is hard. With deep expertise and strong relationships across the regulatory ecosystem globally, I’ll be supporting Vertical in navigating the certification process and ensuring the VX4 becomes the safest aircraft in the market.
“Backed by world-class talent and cutting-edge technology, Vertical is well-positioned to lead the sector, and I’m delighted to be part of this journey.”
During his tenure at Eurocontrol and the IAA, Brennan worked closely with the European Union Aviation Safety Agency (EASA) and helped drive significant advancements in European aviation, including through his advocacy of the Single European Sky programme.
His deep understanding of regulatory frameworks and certification processes across multiple jurisdictions, combined with his expertise in airspace management, will be invaluable as Vertical navigates the complex certification requirements for its eVTOL aircraft, the VX4.
Stuart Simpson, CEO at Vertical Aerospace, said: “We are thrilled to welcome Eamonn to Vertical at such a crucial and exciting stage in our journey. Navigating the regulatory landscape is one of the biggest challenges in pioneering electric aviation, and having someone of Eamonn’s calibre advising us is a huge advantage.
“His insights and experience build on our already strong team in this area and will help us accelerate our certification efforts and shape a new era of travel.”
Mr. Brennan’s arrival follows the recent return of industry veteran Domhnal Slattery as Chair, along with Vertical’s launch of its Flightpath 2030 strategy and successful upsized $90m underwritten public offering.
