The Twenty-fourth meeting of the North Atlantic Safety Oversight Group (NAT SOG/24) was held via teleconference sessions from 01 to 04 June 2021. Representatives from Canada, Denmark, Iceland, Ireland, Norway, Portugal, Spain, United Kingdom and United States were in attendance, as well as the International Air Transport Association (IATA), the International Federation of Air Line Pilots' Associations (IFALPA) and NAT CMA. A number of South Atlantic (SAT) Member States responded to the invitation of NAT SOG and attended NAT SOG/24 meeting as observers.
The meeting allowed for a review of the level of risk as a consequence of operational errors and in-flight contingencies in the North Atlantic high-level airspace, based on the reports from the North Atlantic Central Monitoring Agency (NAT CMA), the NAT Scrutiny Group (NAT SG) and the NAT Mathematician Working Group (NAT MWG). The NAT 2020 Annual Safety Report, containing the safety performance and the collision risk estimates in the NAT Region was also reviewed and will be published on the ICAO EUR/NAT website, pending approval from the North Atlantic Systems Planning Group (NAT SPG). The NAT SOG24 also concluded on the feasibility of the development of a new NAT Height Monitoring System (HMS) in collaboration with NAT ANSPs utilizing existing ADS-B data within the NAT. Outcomes of the NATSOG24 work were transmitted to the NATSPG/57 meeting (virtual, 21-24 June 2021). As soon as finalized, the NATSPG reports are publicized on the ICAO EURNAT official webpage-EUR/NAT Meetings-North Atlantic Systems Planning Group (NAT SPG)-NAT SPG Reports.
