NAV CANADA, the country's provider of civil air navigation services, conducted an aeronautical study that reviewed the requirement for Non-Directional Beacons (NDBs) and Very-High Frequency Omnidirectional Range (VORs).
The study concluded that given the comprehensive radar surveillance coverage, and the propensity of area navigation (RNAV) with GNSS equipped aircraft, many navigation aids (NAVAIDS) are no longer required and should be decommissioned.
Where a current NAVAID identified in the study serves as an instrument approach aid or anchors an airway segment, NAV CANADA will ensure that a RNAV (GNSS) instrument approach procedure or RNAV airway segment is published, where required, before removal of the identified NAVAID.
Implementation of this multi-year project is nearing completion. Subsequent Service Notices will be published for the final upcoming changes.
The Thunder Bay (QT) NDB and Thunder Bay (YQT) VOR will be decommissioned.
This change will take effect on 11 July 2024 at 0901Z Coordinated Universal Time (UTC). The appropriate aeronautical publications will be amended.
