Scott International Procedures
A Gander Domestic trial issues oceanic route amendments via VHF voice instead of CPDLC, before the Oceanic Entry Point.
The procedure change for issuing route amendment clearances in Gander Domestic airspace was conducted as a trial between 5 May 2025 and 31 December 2025. Check current NOTAMs for any changes.
Due to ATC workload and pilot confusion regarding oceanic route clearance changes issued through CPDLC, Gander (CZQX FIR) Domestic controllers issue oceanic route amendments via VHF voice communications in lieu of CPDLC uplink messages.
Post-implementation monitoring of the 4 December 2024 Oceanic Clearance Removal (OCR) identified that some flight crews were confused by the new procedures, increasing ATC workload. To mitigate this, CZQX FIR Domestic ATC issues oceanic route clearances and amendments via VHF voice before an aircraft reaches its Oceanic Entry Point (OEP). Other OCR procedures continue unchanged; route changes past the OEP continue via CPDLC or HF.
