Abstract
As new types of Emerging Technology Aircraft (ETA) enter the market, including Unmanned Aircraft Systems (UAS), eVTOL aircraft, Advance Air Mobility (AAM), and supersonic/hypersonic aircraft, etc., it is crucial to ensure their safe and sustainable integration into existing airspace. These aircraft must exceed current safety and environmental standards, without compromising the efficiency or security of conventional operations. A globally harmonized regulatory framework is essential to maintaining air traffic flow, minimizing environmental impact, and upholding public trust in aviation. This paper outlines key considerations for safely incorporating ETA while preserving airspace integrity and operational efficiency.
