08/07/24 (Agence Europe) – On Friday 5 July, the European Aviation Safety Agency (EASA) updated the Safety Information Bulletin (SIB) on ‘Global Navigation Satellite System (GNSS) Outages and Alterations Leading to Communication, Navigation and Surveillance Degradation’. A second revision was published to warn operators against interference with navigation systems caused by spoofing and jamming of signals, particularly close to conflict zones. This third update takes account of the latest analyses and recent phenomena. Information on the impacted airspace has been moved from the SIB to a dedicated webpage on GNSS outages and alterations. This page can be updated more easily and quickly as new information becomes available. (AD)
