π§ What Changed (Summary)
This AIC describes how Trigger NOTAMs are used in Canada for AIRAC AIP Amendments (AIRAC AIP AMDT) and provides a reminder of Trigger NOTAM application for AIP Supplements (AIP SUP), in line with ICAO Standards and Recommended Practices.
- For AIRAC AIP AMDT in Canada, Trigger NOTAMs are issued every 56-day publication cycle.
- One Trigger NOTAM per NOTAM Region is issued 14 days before the AIRAC effective date and remains in force until 14 days after the AIRAC effective date.
- The Trigger NOTAM lists applicable Canadian aeronautical information products (e.g., AIP Canada, CFS, CAP/RCAP, DAH, and terminal/low/high enroute charts).
- NOTAM Region information reference: AIP Canada GEN 3.1.3.4.
βοΈ General Aviation Impact (Highlighted)
Airspace / Procedures:
- Expect a Trigger NOTAM associated with each AIRAC cycle identifying the related AIRAC AIP AMDT products for that NOTAM Region, issued 14 days prior to the AIRAC effective date and remaining for 14 days after.
Operational Notes:
- Trigger NOTAMs are informational pointers to published AIRAC AIP amendments and AIP Supplements; review the referenced products for the actual changes relevant to your route, aerodrome, and phase of flight.
VFR Impact:
- VFR pilots should anticipate AIRAC-cycle Trigger NOTAMs as a cue to check for chart and publication amendments that may affect routes, airspace depictions, and aerodrome information.
