The North Atlantic Economic, Financial and Forecast Group (NAT EFFG) met in Whiteley, United Kingdom, hosted by NATS UK, on 21–22 October 2026. The meeting reviewed the progress concerning the NAT Height Monitoring System (NAT HMS) Financial Arrangement. Discussions also addressed actual North Atlantic traffic developments in 2026, traffic forecast assumptions, data sources and performance trends, including updates on the work of the NAT Data Mapping Project Team and the NAT Mathematicians Working Group (MWG).
The Group also considered the financial challenges facing the ICAO NAT Region, with updates from air navigation service providers (ANSPs) and the International Air Transport Association (IATA). A further focus was the development of charging mechanisms for commercial space operations, including coordination activities, global guidance and the assessment of potential impacts on airspace users, such as re-routing costs. The meeting also reviewed progress on the NAT Vision and NAT Air Navigation Plan (ANP) Volume III, supporting continued coordination on the region’s economic, financial and traffic forecasting priorities.
