May 20, 2022

Incident at LONDON FIC / FIC DE LONDON (ATM - inaccurate aeronautical information, ATM - weather observation systems)

From 1123Z until 1410Z the NAVNet/aeronautical fixed telecommunications network (AFTN) connection was disrupted at the London flight information centre (FIC). The FIC was unable to send or receive VFR and IFR flight plan data via the flight service station information management system (FIMS) to the appropriate Area Control Centres (ACCs) and FICs. Quebec and Edmonton FICs assisted with IFR flight plan entry. London FIC was unable to enter local weather observations via the Human Weather Observation System (HWOS) or provide weather observation contingency services to designated sites. Quebec FIC provided "buddy" weather services for London. Weather data such as the current meteorological report (METAR), the aerodrome special meteorological report (SPECI), and the Aerodrome Forecast (TAF) were not ingested or available on FIMS. NOTAMs could not be entered on the NOTAM Entry System (NES) on FIMS browsers. Specialists used Collaborative Flight Planning Services (CFPS) and NES on the NAV CANADA intranet (NCI) computers for weather data, pilot weather report (PIREP) entries, and to enter NOTAMs. External CFPS users encountered flight plan error messages and were directed to contact the FIC. There was a significant increase in workload as flight plan data was passed via phone and fax. The internal and external coordination, workload and complexity was high. East Coast air traffic service (ATS) units encountered delays or did not receive electronic strip data for VFR flight plans. When AFTN connection was restored, there were numerous queued and duplicate flight plan data messages that needed to be examined and triaged. The outage was traced to a Zayo telecommunications (Telco) company circuit. Backup routers did not engage.
