NAVAID Modernization Program – Phase 6 National

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 Rangefinders (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 is ongoing and will progress for the next several years. The sixth phase is represented below. Subsequent Notices of Change will be published for each upcoming phase.
