Important
There are additional restrictions on controllers logging on as CN ADC and CN SMC between the hours of 23:00 and 06:00 Sydney local time.
Airspace
CN ADC is responsible for the Class D airspace in the CN CTR SFC to A020.
Refer to Class D Tower Separation Standards for more information.
Night Operations
Controllers are prohibited from logging on as CN ADC or CN SMC between 23:00 and 06:00 Sydney local time.
During this time, the Sydney CTA C10 Airspace overhead YSCN extends to A015, precluding normal operations.
Local Procedures
Start Approval
Start approval is required on SMC for all aircraft intending to operate in the circuit area.
Phraseology
WKM: "Camden Ground, Citabria WKM, for circuits, received Echo, request engine start"
CN SMC: "WKM, Camden Ground, start approved"
WKM: "Start approved, WKM"
Glider Operations
Glider operations are regularly conducted in VMC at YSCN, within the CN CTR remaining south of the duty runway.
Gliders will use the grass strips adjacent to Runway 10/28 for all operations, with circuits performed on the dead side of the field.
The grass strips are outside of the manouevring area, and ATS service to the gliders is limited to traffic information upon receiving an inbound call.
Phraseology
ABC: "Camden Tower, Glider ABC inbound at THK, A008, for glider strip 24"
CN ADC: "ABC, Camden Tower, no reported traffic"
Arriving gliders should also call when joining downwind.
Phraseology
ABC: "Camden Tower, Glider ABC downwind glider strip 24"
CN ADC: "ABC"
Tip
When glider operations are in progress, the ATIS OPR INFO field should be updated to advise other aircraft.
Instrument Approaches
The only instrument approach at YSCN is the RNP W approach. This approach commences within CTA, leaves controlled airspace on descent, and then enters the Camden control zone.
SY TCU will clear aircraft to leave controlled airspace via the approach and will transfer aircraft to CN ADC prior to SC2WI. CN ADC shall issue airways clearance on first contact in accordance with the table below.
| Scenario | Clearance |
|---|---|
| Aircraft is visual & circuit traffic exists | "Cleared RNP-W approach, not below A018" |
| Aircraft not visual or no circuit traffic | "Cleared RNP-W approach, [circuit joining instructions]" |
Example
CN ADC: "AM251, cleared RNP-W approach, join upwind runway 06"
Note
The circuit altitude at YSCN is A013 and the overfly altitude is A018. Aircraft issued a restriction to descend not below A018 should be instructed to join the circuit once clear of traffic established in the circuit area.
VFR Operations
Departures
All aircraft must depart at A013 via an extended leg of the circuit.
Upon reaching 2NM CN, all VFR aircraft should monitor the appropriate area frequency (SYC). A frequency transfer will not be issued to VFR aircraft.
Departing IFR aircraft will receive a frequency transfer.
Depart On Climb
Some aircraft may request to leave the CTR on climb above A013. If there is no reported traffic above the zone and no conflicting traffic at A018, aircraft may be cleared to depart on climb.
Phraseology
CN ADC: "PCN, runway 06, cleared for takeoff"
PCN: "Runway 06, cleared for takeoff, PCN"
PCN: "PCN, request depart on climb"
CN ADC: "PCN, depart on climb"
Arrivals
VFR Inbound Procedures
VFR aircraft should track via one of the VFR inbound points and be instructed as below:
| VFR Approach Point | RWYs 06 | RWYs 24 |
|---|---|---|
| MEG | "Overfly Camden to join Mid-Field Crosswind RWY 06, Maintain A018, Report Overhead" | "Overfly Camden to join Mid-Field Crosswind RWY 24, Maintain A018, Report Overhead" |
| PIC | "Overfly Camden to join Mid-Field Crosswind RWY 06, Maintain 1800ft, Report Overhead" | "Overfly Camden to join Mid-Field Crosswind RWY 24, Maintain A018, Report Overhead" |
| THK | "Join Final RWY 06, Maintain A018, Report 3NM" | "Join Downwind RWY 24, Maintain A018, Report 2NM" |
When Aircraft are clear of conflicting traffic below, aircraft may be "cleared visual approach".
When an aircraft reports at their specified report point (or on downwind), issue the aircraft its sequence in the circuit.
Phraseology
CN ADC: "XEM, number 3 Runway 06, follow the C172 on base"
Circuits
The circuit direction changes depending on time of day and runway being used.
| Runway | Day | Night |
|---|---|---|
| 06 | Left | Left |
| 24 | Right | Right |
| 10 (Grass) | Left | - |
| 28 (Grass) | Right | - |
Circuits are flown at A013 (High Performance Aircraft: A018)
When an aircraft reports on downwind, indicate their position in the sequence (and give a follow instruction if the sequence has changed since the last circuit).
Phraseology
JKA: "JKA, downwind, touch and go"
CN ADC: "JKA, number 2"
ATIS
Approach Types
| Cloud Base | Visibility | Approach |
|---|---|---|
At or above A035 |
>5000M | (blank) |
Below A035 or |
<5000M | EXP INST APCH |
Operational Info
When glider operations are being conducted, the OPR INFO field should be updated to include GLIDER OPS IN PROG.
Coordination
Departures
CN ADC must advise SY TCU when the aircraft has called 'Ready'. In response to a ready call, SY TCU will issue a traffic statement.
Phraseology
CN ADC -> SYC: "Ready, MHQ, Runway 06"
SYC -> CN ADC: "MHQ, traffic is MEH, an IFR AC50, tracking SHL RAKSO SB2WI, A035, estimate RAKSO time 35" (or "No Reported IFR Traffic")
CN ADC -> SYC: "Traffic is MEH tracking SHL RAKSO SB2WI A035, RAKSO at 35"
CN ADC: "MHQ, traffic is MEH, IFR AC50 tracking SHL RAKSO SB2WI at A035, estimating RAKSO at time 35, runway 06, cleared for takeoff"
MHQ: "Runway 06, cleared for takeoff, MHQ"
CN ADC: "MHQ, contact Sydney Centre on 124.55"
Note
Note: Because aircraft enter Class G after departure, an airways clearance should not be issued by CN ADC. This will be done on first contact with Sydney TCU. Therefore, departure instructions are not required. You must however, pass the above (ready) coordination & obtain a traffic statement.
Arrivals/Overfliers
SY TCU will coordinate inbound IFR aircraft. CN ADC is responsible for issuing a clearance into the CN CTR and for coordination with SY TCU in the event of a missed approach (or on completion of airwork if applicable).
SY TCU will NOT clear the aircraft for the approach.
Phraseology
SYC -> CN ADC: “via RNP W, HRP”
CN ADC -> SYC: “HRP”
CN ADC must issue an airways clearance to these aircraft on first contact.
IFR overflying YSCN
SYC will advise CN ADC of observed IFR aircraft overflying CN CTR below A025.
