Air navigation is increasingly moving from traditional navigation using ground-based sensors to performance-based navigation (PBN). This involves transitioning to area navigation by implementing navigation specifications and encompasses both Area Navigation (RNAV) and Required Navigation Performance (RNP).
Transport Canada has published a PBN State Plan to assist the Canadian aviation community in the transition to RNAV and RNP concepts and to help plan future transition and investment strategies. The plan is accessible here, as well as from the link below.

NAV CANADA has published a PBN Operations Plan, developed collaboratively with our customers in recognition of the shared role, responsibility and benefits that PBN represents, to identify our priorities and future opportunities. The plan is accessible here, as well as from the link below.

The PBN State Plan and the PBN Opetrations Plan explain in detail the different types of PBN instrument approach procedures. Essentially, PBN approaches are titled according to the lines of minima available on the chart. Approaches published using the chart title 'RNAV (GNSS)' can offer up to three PBN lines of minima: lateral navigation (LNAV), Lateral Navigation/Vertical Navigation (LNAV/VNAV) and /or Localizer Performance with Vertical guidance (LPV). Some PBN approaches require special authorization prior to use. In these cases, the procedures are published under the chart title 'RNAV (RNP)'; they are annotated with Authorization Required (AR) and are referred to as RNP AR approaches. Maps depicting the location of Canadian PBN procedures are available from the links below.

NAV CANADA has produced a video series addressing common aspects of flight operations when using PBN STARs. The series is available here, as well as from the link below.
