Separation

Surveillance

Surveillance coverage can be expected to be available at all levels in the AYNZ CTR. Although AYNZ ADC is not permitted to use surveillance for separation, AYPM may assist by establishing surveillance separation standards via coordination.

Lateral Separation Points

The Markham River runs East-West through the AYNZ CTR south of the Runway 09/27 centreline.

Its prominence and location makes it a convenient option to implement a geographic feature separation standard.

Local Procedures

Standard Departure Clearances

In lieu of a SID, departing aircraft may be issued with a Standard Departure Clearance (SDC). Aircraft cleared via an SDC will depart the circuit visually, and then intercept the track specified by five miles.

AYNZ ADC will clear relevant departures via the appropriate coded SDC, write the departure name in the Global Ops Field.

Phraseology

AYNZ ADC: "...cleared to Guam via Departure 35 then PIKOK flight planned route..."

A list of the Standard Departure Clearances is available in the AIP Flight Supplement.

SID Selection

There are no SIDs at AYNZ. In VMC by day, all aircraft shall be assigned a visual departure.

Otherwise:

  • IFR aircraft departing via MUDIX shall be assigned the GOROKA 1 or GOROKA 2 DME departure.
  • IFR aircraft departing via LARID shall be assigned the LAE DME departure.
  • IFR aircraft not departing via MUDIX or LARID should be assigned an SDC and/or sector DME departure.

Coordination

Departures

Next coordination is required from AYNZ ADC to AYNZA for all aircraft entering AYNZA CTA.

The Standard Assignable Level from AYNZ ADC to AYNZA is:

Aircraft Level
All The lower of A050 and RFL

Arrivals

AYNZA will heads-up coordinate all arrivals/overfliers to AYNZ ADC.

  • Aircraft on an instrument approach will be cleared for the approach prior to handoff to AYNZ ADC, unless AYNZ ADC nominates a restriction.
  • Aircraft on a visual approach will be coordinated, but will receive their approach clearance and circuit joining instructions from AYNZ ADC.

Phraseology

AYNZA -> AYNZ ADC: "Via LARID for the RNAV, PXB.”
AYNZ ADC -> AYNZA: "PXB."
