✈️ New Aeronautical Information Circular (AIC) Detected
AIC: AIC 020/2025
Published: 2025-10-02
🧠 What Changed (Summary)
This AIC provides AIRAC 2025–2026 key dates and guidance for Canadian originators submitting aeronautical information/data changes to NAV CANADA (AIS Provider), emphasizing required lead times—especially for changes affecting instrument flight procedures.
- AIRAC system overview and importance of publishing changes on common effective dates to support timely navigation database (FMS) updates.
- For major/complex projects, contact NAV CANADA (aisdata@navcanada.ca) at least 18–24 months in advance to state intent and coordinate interdependent changes.
- Directs originators to NAV CANADA data submission guidance: https://www.navcanada.ca/en/aeronautical-information/data-submission.aspx
- Table of deadlines showing two submission cut-off streams: (1) changes affecting instrument flight procedures, and (2) editorial/non-instrument-procedure-impacting changes, aligned to AIRAC effective dates.
- AIRAC effective dates listed in the excerpt run from 14 May 2026 through 6 Jul 2028 (with corresponding submission deadlines shown for each cycle).
✈️ General Aviation Impact (Highlighted)
Airspace / Procedures:
- If you (or your organization/airport) originate changes to instrument procedures (SID/STAR/IAP), plan submissions to meet the earlier cut-off dates so updates are published in time for FMS/database cycles.
- Avoid reliance on NOTAM as a primary means to implement enduring changes; the AIC notes aligning work to AIRAC effective dates minimizes disruption and supports safety-critical loading into FMS.
Operational Notes:
- GA operators should expect that permanent procedure/data changes will typically be implemented on AIRAC effective dates; monitor AIRAC cycles when planning operations at aerodromes undergoing changes.
- The excerpt does not specify any immediate airspace/procedure changes for pilots; it is an administrative/calendar guidance document for data originators.
VFR Impact:
- Primarily indirect: VFR pilots may see chart/publication updates aligned to AIRAC cycles; timely submission helps reduce extended NOTAM use and mismatches between published information and onboard databases.
