The next frontier of flight
As aviation enters an era of unprecedented transformation, the airspace well above conventional passenger traffic is preparing for a new wave of diverse operations. From solar-powered High-Altitude Platform Systems (HAPS) to supersonic transports and highly automated uncrewed systems, the upper atmosphere is the next frontier of flight.
But how do we safely scale these operations across international borders while keeping our skies seamlessly integrated?
Slated for a landmark trial in 2028 over the high seas under the supervision of participating States, this initiative is the first international cooperative deconfliction exercise for Higher Airspace Operations (HAO). It serves as a vital proving ground where regulators, Air Navigation Service Providers (ANSPs), and operators can collaboratively test the digital, intent-sharing, and coordination tools that will define the future of Air Traffic Management.
The paper outlines how this sandbox will help:
- Prevent airspace fragmentation by building a shared international evidence base before national architectures harden.
- Inform how ANSPs might transition from predominantly tactical control towards more interconnected and increasingly strategic airspace management.
- Support the development of future ICAO guidance by leveraging real world operational experience, data, and evidence-based findings.
Whether your focus is conventional ATM or the future of flight at 65,000 feet, this paper serves as a blueprint for a seamless, digitally enabled globally integrated airspace!
