βοΈ General Aviation Impact (Highlighted)
Airspace / Procedures:
- Expect possible temporary procedure impacts to be issued separately (e.g., via NOTAM or publication amendment) if required by the crane activity.
Operational Notes:
- Increased obstacle hazard near CYQS, particularly for arrivals/departures and low-level operations northwest of the aerodrome.
- Unlit/unpainted cranes increase night/low-visibility risk; use extra caution even in day VMC when operating near the published coordinates and radius.
VFR Impact:
- VFR pilots operating near CYQS should plan to avoid the crane area and maintain adequate obstacle clearance, especially in the circuit/transition area to the NW.
