For radar departures use the phraseology: "...Christchurch One Alpha Departure, Heading 020..."

1.3.2 - International Clearances

International Clearances shall be issued in accordance with the Delivery Tutorial Section 2: IFR Clearances.

International Flights which file routes that have an Oceanic Boundary fix between KABKA, south to KABIN shall be assigned an Oceanic Transition, with their requested cruise level being omitted from the route clearance.

1.3.3 - Flight Plan Annotation

The flight plan shall be annotated to display the SID being used by the flight.

1.4 - VFR Departure Clearances (Western Apron Only)

VFR aircraft shall be, in the first instance, assigned a published departure procedure appropriate for their direction of flight.  If the pilot is unfamiliar with a published procedure, a plain langugage clearance may be issued to the pilot.  The VFR flight strip should be amended to display the departure procedure/plain language clearance that was issued.  VFR aircraft shall be taxiied to an appropriate holding point for the Grass or Runway in use.

1.5 - IFR Departures (Western Apron Only)

IFR aircraft parked on the Western Apron shall call Delivery for start up advise.  Delivery shall advise of any delays.  IFR aircraft using the grass runway for departure shall be taxiied to an appropriate holding point for the Grass Runway in use.  IFR aircraft using the main runway shall be taxiied to Hold 1 (Runway 02/20/29) or E1/E2 (Runway 11) initially.

1.6 - Transfer of Communications

Once a correct readback has been obtained, Delivery shall advise the aircraft to monitor Christchurch Ground.  IFR and VFR aircraft from the Western Apron shall be advised to monitor Christchurch Tower.

Section 2: Ground Control

2.1 - Responsibilities

Christchurch Ground is responsible for issuing taxi instructions and providing separation to all aircraft on the taxiways at Christchurch Airport (NZCH), as well a issuing VFR clearances to aircraft on the main apron.

2.2 - Frequency and Callsign Information

2.3 - Pushback and Start Up advice

Christchurch Ground shall issue pushback and/or start up advice to all aircraft - this includes the International Apron.  Ground shall use positive control to ensure that no other aircraft will pass directly behind an aircraft that is pushing back.

2.4 - Use of holding points

Ground may assign the following reduced length holding points for departure without the approval of the pilot

TypeRunway 02Runway 20
A320/B737A6-
AT75/DH8CA5/RWY29A3/A4

2.5 - Taxi Phraseologies

Should tthere be a need to taxi an aircraft to an intermediate taxiway which is not a runway holding point, use the phraseology: "(callsign) taxi for (runway) via Alpha, Hold Short of Runway 29"

2.6 - Transfer of Communications

Once ground has issued all necessary instructions to the pilot, they shall advise the pilot to monitor Christchurch Tower.

Section 3: Aerodrome Control

3.1 - Responsibilities

Christchurch Tower is reponsible for all IFR and VFR aircraft operating within the CH CTR/C, from SFC-2500ft as well as all runways at Christchurch Airport (NZCH).

Tower is responsible for selecting the most suitable runway-in-use.

In most cases, the runway-in-use will be the runway which is most into wind. This is because aircraft prefer to take off & land into wind.

However, in some cases, due to runway length, available approach and landing aids, position of the sun or the types of aircraft that use the runway, the most into wind runway may not be most suitable runway. It is up to the tower to balance these factors when selecting the runway-in-use.

To avoid head on collisions & to maintain seperation between arriving & departing aircraft, only one end of a runway can be-in-use.

The runway-in-use shall be included in the ATIS report.

3.2 - Frequency and Callsign Information

3.3 - IFR Arrivals

Arrivals on an instrument approach shall be given their sequence on first contact.  Arrival on a visual approach shall be given joining instructions and sequence on first contact.

3.4 - IFR Departures

Tower may clear aircraft for take off without reference to a TMA or CTR controller. This is called "Auto Release".

The following best practice, should be taken into consideration when releasing aircraft for take off:

1. A landing aircraft will not be forced to go around.

2. Wake turbulence separations.

  • Normally two minutes.
  • Exception of three minutes when following aircraft is departing from an intersection.

Please refer to the Moodle ADC Course, Section 7.3 for complete details.

3. Thirty degree successive IFR departures.

Two departing IFR aircraft are considered separated if the following conditions are met:

  • The initial departure tracks of both aircraft diverge by 30 degrees or more; and
  • The preceding aircraft has been observed to clear and be moving away from the departure track of the  following aircraft; and
  • The preceding aircraft has reached a point where it is safe distance ahead of the following aircraft.

Please refer to the Moodle ADC Course Section 7.4 for complete details.

4. Straight out departure.

  • The previous departure is at least 5nm straight ahead of the runway & 2000 feet AGL, assuming aircraft with similar performance. i.e. jet following jet or turbprop following turboprop

 Auto Release may be cancelled by the TMA or CTR controller during periods of high workload. The termination and reinstatement of auto release will be negotiated between the relevant controllers.

Auto Release may not be used for departures on a runway other than the duty runway.

Tower shall annotate the flight plan to display the SID being used by the aircraft.

3.5 - VFR Flights

VFR aircraft in the North or South sector (As depicted in the Christchurch VFR Arrivals/Departures page in the AIP) are considered separated from IFR traffic on the instrument final approach.  VFR arrivals shall be assigned a published VFR arrival procedure.  If traffic permits, direct joining instructions may be issued instead.  Aircraft vacating to the east from runway 02  may be instructed to make a right turn after departure and aircraft vacating east from runway 20 may be instructed to make a left turn after takeoff.

3.6 - Transfer of Communications

Arriving Aircraft - Once the aircraft has vacated the runway.

Departing Aircraft - Once airbourne.

Section 4: Adjacent Sector Procedures (Christchurch Terminal)

4.1 - Area of Responsibility

Christchurch Terminal is responsible for all aircraft within the Christchurch CTA/C.

4.2 - IFR Departures

Auto release (Refer 3.4) applies.

Christchurch Tower shall coordinate with terminal prior to assigning an aircraft a crossing runway for departure.  A release is required prior to clearing an IFR aircraft for take off from a crossing runway.

4.3 - IFR Arrivals

Christchurch Terminal shall restrict aircraft on a visual approach to 2000ft unless otherwise coordinated.  No descent restrictions apply to aircraft on a published visual approach procedure.  Aircraft on an instrument approach may descend below 2000ft in accordance with the published profile.

4.4 - Transfer of Control

All Departures - Passing 2000ft unless otherwise coordinated.

All Arrivals - Within 10 CH DME.

4.5 - Transfer of Communications

All Departures - Airborne, unless otherwise coordinated.

Arrivals (on an instrument approach) - at ALBAD or DIVSU, established on a straight in approach.

Arrivals (on a visual approach/arrival) - 15 CH DME.
