Coordination and Procedures with Adjacent Sectors

CHAPTER 3

3.1 Reykjavík ACC (BIRD)

Reykjavík provides a domestic radar service and borders the Northern edge of the Gander OCA.

Attribute Details
RTF Callsign Reykjavik Control
Equipment Non-radar
Lateral Separation Minima 10NM at and above FL270, 5NM below FL270
Longitudinal Separation Minima 10NM at and above FL270, 5NM below FL270
Special Transfer Conditions None

Note: BIRD_1_CTR is the bandbox position and covers all BIRD sectors top-down.

3.1.1 West Sector

BIRD_6_CTR
124.400 MHz
BIRD_1_CTR
119.700 MHz

3.1.2 South Sector

Note: The south sector can be dynamically split (vertically) according to demand, refer to the diagram for the correct sector.

BIRD_1_CTR
119.700 MHz
BIRD_2_CTR
125.700 MHz
BIRD_3_CTR
128.600 MHz

3.2 New York Oceanic ARTCC (KZWY)

New York Oceanic provides a procedural service augmented by ADS-C, with 15NM longitudinal and 30 NM lateral separation between eligible aircraft pairs. ZWY borders Gander to the South West between Gander Domestic and Santa Maria. All handoffs are to the Mercury Sector (21-24 on the diagram below). New York delegates a rectangle of airspace to Gander Oceanic North of N45 30’, between 40W and 50W up to the FIR boundary. New York also delegates another portion of airspace to Gander (domestic) to the west of this rectangle.

3.2.2 Mercury High (FL365 - UNL)

The Mercury sector split is established at FL365 by default, but this level can be varied according to demand.

NY_MH_FSS
21.925 MHz (130.650 MHz)

3.3 Santa Maria OAC (LPPO)

Santa Maria provides a mixture of radar and procedural services within their FIR. Radar stations at the Azores allow for a central area of radar coverage surrounded by procedurally controlled airspace which Gander borders. All handoffs are to the primary non-radar sector.

Attribute Details
RTF Callsign Santa Maria Radio
Equipment Non-radar
Lateral Separation Minima 50NM
Longitudinal Separation Minima 10 Minutes
Special Transfer Conditions None

3.4 Montreal ACC (CZUL)

Montreal provides a domestic radar service. Sectors are split vertically at FL290, of which the lower sectors share boundaries with Gander Oceanic underneath the GOTA.

Attribute Details
RTF Callsign Montreal Center
Equipment Radar equipped
Lateral Separation Minima 5NM
Longitudinal Separation Minima 5NM
Special Transfer Conditions None

Note: MTL_TH_CTR may be used instead of MTL_CTR when the sector is split.

3.5 Gander (Domestic) ACC (CZQX)

Gander (domestic) provides a domestic radar service. Gander (domestic) is delegated the following areas by adjacent sectors: - The Gander Oceanic Transition Area (GOTA) at FL290 and above - A small fillet of airspace west of 50W in the southwest corner of the Gander OCA by Gander Oceanic - An area of airspace south of 45N and west of 50W by New York Oceanic.

When Gander is offline, its airspace is covered top-down by Moncton Center.
