CPDLC
The Primary Communication Method for OLW is CPDLC.
The CPDLC Station Code is YOLW.
Voice may be used in lieu when applicable.
Airspace
OLW is responsible for POT, PAR, NEW, MEK, MTK and MZI when they are offline.
Reclassifications
KA CTR
When KA ADC is offline, KA CTR (Class D SFC to A055) reverts to Class G, and is administered by OLW. Alternatively, OLW may provide a top-down procedural service if they wish.
Tip
If choosing not to provide a top down service, consider publishing an ATIS Zulu for the aerodrome, to inform pilots about the airspace reclassification. The More ATIS plugin has a formatted Zulu ATIS message.
Sector Responsibilities
OLW is responsible for issuing descent and ascertaining arrival intentions for aircraft bound for YPKA. OLW is also responsible for sequencing and issuing descent to aircraft bound for YPLM.
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 |
|---|---|---|---|
| MEK, MTK, MZI | PIY(GVE, HYD) | YPPH, YPEA | Jets only |
Coordination
Enroute
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 50nm to boundary.
OLW Internal
As per Standard coordination procedures, Voiceless, no changes to route or CFL within 50nm to boundary.
KA ADC
Airspace
KA ADC is responsible for the Class D airspace in the KA CTR SFC to A055.
Refer to Reclassifications for operations when KA ADC is offline.
Departures
Departures from YPKA in to OLW CTA will be coordinated when ready for departure.
Example
KA ADC -> OLW: "Next, OHN"
OLW -> KA ADC: "OHN, Unrestricted"
KA ADC -> OLW: "OHN"
The Standard Assignable level from KA ADC to OLW is the lower of A050 or the RFL, any other level must be prior coordinated.
Arrivals
YPKA arrivals shall be heads-up coordinated to KA ADC from OLW prior to 5 mins from the boundary.
Example
OLW -> KA ADC: "Via MCNAB, QFA1214 for the RNP U RWY 26”
KA ADC -> OLW: "QFA1214, RNP U RWY 26"
The Standard Assignable level from OLW to KA ADC is A060, any other level must be prior coordinated.
LM TCU
Airspace
The limits of the LM TCU are SFC to F280 within 40 DME LM. This may be amended by NOTAM.
Arrivals/Overfliers
The Standard assignable level from OLW to LM TCU is F130, tracking via LM VOR.
All other aircraft must be voice coordinated to LM TCU prior to 20nm from the boundary.
Departures
The Standard Assignable level from LM TCU to OLW is F240, and tracking via their planned route.
LM ADC
When LM TCU is offline, coordination is not required between OLW and LM ADC. Aircraft entering LM ADC airspace shall be handed off, and instructed to contact LM ADC for onwards clearance.
LM ADC owns the Class C airspace within the LM CTR from SFC to A015.
IND,INE (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.
Example
OLW: "QFA121, identification terminated, report position to Brisbane Radio, 129.25"
