“New entrants” is a term capturing the essence of aerial innovation. It refers to the groundbreaking technologies entering European airspace, such as space launch and sub-orbital operations, High Altitude Platform Systems (HAPS), and the swift advancements in supersonic and hypersonic aircraft. These technologies are not just enhancing the scope of what’s possible in aviation but are also redefining the boundaries of air travel and operations. Through the ECHO2 project, these novel vehicles are being seamlessly integrated into air traffic management systems, promising a future where European skies are safer, more connected, and at the forefront of global aviation innovation. This initiative not only supports the growth of new aerospace ventures but also ensures that Europe remains a leader in embracing and regulating these high-tech aerial operations for the benefit of all.
