CPDLC
The Primary Communication Method for ISA is CPDLC.
The CPDLC Station Code is YISA.
Voice may be used in lieu when applicable.
Airspace
ISA is responsible for ARA, STR, WEG, and CVN when they are offline.
Extending
Important
Due to the large geographical area covered by this sector and it's neighbours, controllers are reminded of their obligations under the ATS Policy when extending. Ensure that you have sufficiently placed visibility points to cover your primary sector and any secondary, extended sectors in their entirety.
Sector Responsibilities
ISA and its subsectors are purely Classes A, E and G of airspace. Standard separation procedures apply. ARA is responsible for sequencing and issuing descent to aircraft bound for YBSG.
STAR Clearance Expectation
Handoff
Aircraft being transferred to the following sectors shall be told to Expect STAR Clearance on handoff:
| Transferring Sector | Receiving Sector | ADES | Notes |
|---|---|---|---|
| CVN | INL(KPL) | YBBN, YBCG | Jets only |
| CVN | INL(DOS) | YBBN | |
| ARA | TRT | YPDN | |
| ARA, ISA | KEN(BAR, KEN) | YBCS | |
| ISA | KEN(TBP) | YBTL |
Coordination
Enroute
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 50nm to boundary.
SG TCU
Airspace
The limits of the SG TCU are SFC to F245 within 40 NM of the YBSG ARP. This may be amended by NOTAM.
Arrivals/Overfliers
The Standard assignable level from ARA to SG TCU is F130, tracking via WP VOR.
All other aircraft must be voice coordinated to SG TCU prior to 20nm from the boundary.
Departures
The Standard Assignable level from SG TCU to ARA is F240, and tracking via their planned route.
SG ADC
When SG TCU is offline, coordination is not required between ISA(ARA) and SG ADC. Aircraft entering SG ADC airspace shall be handed off, and instructed to contact SG ADC for onwards clearance.
SG ADC owns the Class C airspace within the SG CTR from SFC to A015.
ISA Internal
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 50nm to boundary.
TSN(COL) (Oceanic)
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 15 mins to boundary.
Aircraft must have their identification terminated and be instructed to make a position report on first contact with the next (procedural) sector.
Phraseology
ISA: "QFA121, identification terminated, report position to Brisbane Radio, 126.45"
International (AYPM)
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 15 mins to boundary.
International (WAAF)
As per Standard coordination procedures, Heads-up Coordination required for all aircraft prior to 30 mins from boundary.
Phraseology
ARA -> WAAF CTR: "Estimate, CEB40, TOREX time 59, F360"
WAAF CTR -> ARA: "CEB40, F360"
