✈️ New Aeronautical Information Circular (AIC) Detected

AIC: AIC 019/2025

Published: 2025-05-15

🧠 What Changed (Summary)

NAV CANADA advises that ILS Special Authorization (SA) CAT II approaches are being introduced in Canada. These procedures can allow operations to decision heights as low as 100 ft and RVR as low as 1200 ft under certain conditions, and differ from conventional CAT II in that they may use approach/runway lighting intended for CAT I. The first Canadian ILS SA CAT II approach is planned for publication in the Canada Air Pilot on 02 Oct 2025 for Ottawa/Macdonald-Cartier Intl (CYOW) RWY 07.

ILS SA CAT II: may permit DH as low as 100 ft and RVR as low as 1200 ft (under certain conditions).
Key difference vs conventional CAT II: SA CAT II may only have CAT I-intended approach/runway lighting systems.
First planned Canadian ILS SA CAT II procedure: CYOW RWY 07, to be published in the Canada Air Pilot on 02 Oct 2025.
Authorization pathway: eligible operators (CARs 704/705 AOC, CARs 604 PORD, CARs 701 FAOC) should refer to Transport Canada AC 700-053 for requirements.

✈️ General Aviation Impact (Highlighted)

Airspace / Procedures:

Expect a new published ILS SA CAT II procedure for CYOW RWY 07 in the Canada Air Pilot effective 02 Oct 2025 (as stated in this excerpt).
Operations to SA CAT II minima require Transport Canada special authorization; not available to pilots/operators without the appropriate authorization.

Operational Notes:

SA CAT II can improve airport accessibility in poor weather for authorized operators by permitting lower DH/RVR than standard CAT I operations.
Because SA CAT II may be supported by CAT I-intended lighting, pilots should ensure they understand the specific lighting/operational conditions and authorization requirements referenced by Transport Canada (AC 700-053).

VFR Impact:

No direct VFR procedural change identified in the provided excerpt; impact is primarily for authorized IFR operations in low visibility.
