Eamonn Brennan has been a central figure in European aviation for many years, including serving as director general of Eurocontrol from 2018 to 2022, and chief executive of the Irish Aviation Authority (IAA) from 2003 to 2017. During both roles he 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.
He is currently a non-executive director of Ryanair, Europe’s largest airline, and a board member at ANRA Technologies, a global leader in uncrewed traffic management and operation solutions. He also serves on the advisory board of Cirium, an aviation analytics firm.
Brennan’s 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.
A pivotal time for certification
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. During this phase, the VX4 prototype will take off, fly, and land like a conventional aircraft, with lift generated by its wings rather than its rotors. Transitioning from a tightly controlled test environment, with a pilot on board, to more dynamic, scalable operations is a major leap forward on the path to full certification and commercial viability.
Once the aircraft has completed wingborne flight, it will have, in effect, completed a mini-certification process with this prototype.
Brennan 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.”
Vertical Aerospace CEO Stuart Simpson 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.”
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.
