Airspace
The Invercargill CTR/D follows the inner lateral boundries shown below from SFC to A015. The CTR/D is comprised of three sectors - North, South and Instrument.
The wider Invercargill CTA/D follows the outer boundaries as shown below, with the vertical boundaries also listed in their respective sector. Invercargill's airspace upper limit is A095.
Invercargill Tower provides a Procedural Approach service for the wider CTA/D and an uncontrolled service into Ryans Creek.
Areas of Responsibility
Invercargill's main apron has five stands. The areas of responsibility are as depicted below.
Pushback and Taxi
Pushback and startup clearance from stand one to five is managed by Tower. Controllers can make use of a "tail-facing" instruction to manage direction of pushback.
An aircraft may be given a combined taxi/backtrack instruction, Traffic permitting. Aircraft may advise the controller they are able to accept an intersection departure, therefore they may be taxiied to the holding point, omiting the backtrack instruction.
Taxi Backtrack Instruction
ZK-ELT: "ELT, request taxi."
Invercargill Tower: "ELT, via A, enter backtrack, lineup runway 22, cross grass 22"
Crossing Grass Runways
If aircraft are required to cross more than one grass runway during their taxi, the controller must issue an additional clearance.
Invercargill Tower: "ELT, enter backtrack line up runway 04, cross all grass runways"
Departures
IFR traffic departing via ADLUP shall be handed off to STH either crossing KELSO or passing A095. Other IFR departures shall be handed off to the appropriate sector either crossing the lateral boundary of the airspace or passing the upper limit of A095 - whichever comes first.
SID Assignment
The controller shall assign the SID that is suggested by their Controller Client noting the steep climb gradient to FL150 required by SIDs via ANOPA .
STAR Clearances
Tower is responsible for issuing STAR clearances for aircraft bound for Dunedin and Queenstown with reference to the QN and DN ATIS for the appropriate STARs.
Arrivals
STH, QTMA, and DN TWR shall issue STARs to arrivals without coordination with Invercargill Tower. Invercargill Tower may choose to coordinate with the adjacent sectors or amend the arrival on first contact.
Runway 04
All RNAV arrivals terminate at ESNUP or EGAMU, which is the IAF for the RNP approach. Aircraft for the VOR approach will track direct to the NV VOR. Aircraft for the VOR DME approach will either track to the NV VOR , direct to PEBLY, or join the NV DME 10 DME arc depending on the aircraft's position.
| Preference | Approach |
|---|---|
| 1 | RNP RWY |
| 2 | VOR DME |
| 3 | VOR |
Runway 22
All RNAV arrivals terminate at either LALEV or DOTLU, which are the IAF for the RNP approach. Aircraft for the VOR approach will track direct to the NV VOR. Aircraft for the VOR DME approach will either track to the NV VOR, direct to PEBLY, or join the NV DME 10 DME arc depending on the aircraft's position.
| Preference | Approach |
|---|---|
| 1 | RNP RWY |
| 2 | VOR DME |
| 3 | VOR |
VFR Procedures
NZNV has no published VFR procedures. VFR traffic shall be issued plain language instructions.
Coordination
Handovers
Due to the nature of procedural airspace the TWR controller shall note the following positions where aircraft are transferred.
For Arrivals:
| Scenario | Handover Point |
|---|---|
NZDN to NZNV via H402 |
51nm outbound from NV DME |
NZDN to NZNV via H234 |
OREXI |
NZDN to NZNV via AKPIN |
AKPIN |
via DUKOP |
DUKOP |
For Departures:
| Scenario | Handover Point |
|---|---|
W118 to the North |
KELSO |
Q787 to the North |
20nm prior to SUNGU |
STH
Tower is normally not required to advise STH of any departing IFR traffic, and may conduct a silent handover per the list above, IFR aircraft shall cross the common airspace boundary overhead an IFR waypoint, or established on an airway.
All VFR traffic handovers shall be coordinated with STH.
QTMA
Tower is normally not required to advise QTMA of any departing IFR traffic, and may conduct a silent handover as per the list above. Except where previously coordinated, IFR aircraft shall cross the common airspace boundary overhead an IFR waypoint, or established on an airway.
All VFR traffic handovers shall be coordinated with QTMA.
DN TWR
Tower shall coordinate all traffic handovers with DN TWR, and shall advise the aircraft's current and cleared altitude, and estimated time that they will be crossing the common airspace boundary, or handover point as defined in the handover table.
Ryans Creek Uncontrolled IFR
Ryans Creek (NZRC) is a small uncontrolled aerodrome 30 nm south of Invercargill.
Departures
IFR aircraft on the ground at RC shall call TNV prior to taxi to obtain IFR clearance. After a correct readback aircraft shall be cleared to enter controlled airspace via SEBSA 1 departure. Aircraft are then advised to report prior to entering controlled airspace.
Arrivals
TNV shall clear the aircraft to leave controlled airspace via the RNAV approach for runway 22. The aircraft shall be instsructed to report on the ground to cancel their IFR flight plan.
