Ohakea TMA

Section 1: General

1.1 Area of Responsibility:

NZOH_APP (Ohakea Approach) is responsible for all controlled airspace within their designated area of responsibility (see diagram), excluding Palmerston and Ohakea Towers when those units are online.

Controls up to 11,000ft.

1.2 Frequency and Sector Information:

Section 2: Arrivals

2.1 Direct Routings on STARS

When traffic permits, Approach may 'shortcut' arrivals by tracking them direct to an appropriate base/final waypoint.

Palmerston North Runway 07:

Aircraft South of NZPM: Direct to GUNTI
Aircraft West of NZPM: Direct to GUNTI 
Aircraft North of NZPM: Direct to NIRUB
Aircraft East of NZPM: Direct to NIRUB or circling GUNTI

Palmerston North Runway 25:

Aircraft South and West of NZPM Direct to NIKIP
Aircraft North of NZPM: Direct to LEKED
Aircraft East of NZPM: Direct to NIKIP, LEKED, or UVUSI

Ensure that all aircraft are well above the MSA

Ohakea Runway 09:

All arrivals via 6DME OH 09

Ohakea Runway 27:

Arrivals via a 6.8DME OH 27

Ohakea Runway 15:

Arrivals via a 13.2DME OH 15

Ohakea Runway 33:

Arrivals via a 13DME OH 33

2.2 Aircraft for Palmerston North RWY25

In strong wind conditions, aircraft may encounter severe turbulence, downdraughts and lee waves. Winds over the ranges maybe 2 to 3 times stronger than the Palmerston North aerodrome surface wind. On occasions when the reported surface wind at Palmerston North exceeds 15 knots, all suitably equipped aircraft carrying out an approach to RWY 25 are requested to provide ATC with information on wind strength, turbulence and downdraughts encountered in the approach area.

2.3 Aircraft for Visual Approach Palmerston North RWY07/25

It is a pilot’s responsibility to ensure containment of their flight within controlled airspace when on a visual approach. Caution should be exercised to avoid conflict with possible traffic in class G airspace surrounding Palmerston North CTR/D. This is especially relevant for arrivals from the north and traffic in the vicinity of Feilding aerodrome

2.4 Aircraft joining for Ohakea

Aircraft being vectored downwind for an instrument approach (all RWYs) are to intercept and track via the 15 OH DME arc towards final approach if no downwind extension or base turn instructions are received from ATC.

Pilots are required to advise ATC when joining the DME arc.

Section 3: Departures

3.1 Noise Abatement Procedures Palmerston North:

To avoid possible noise nuisance to Palmerston North city between 2200 and 0700hrs (local), aircraft should adopt the following noise abatement procedures, except
in adverse conditions or as directed by ATC:

• No aircraft to fly over the populated areas between the extended runway centreline and the Manawatu River at altitudes lower than 3000ft
• Aircraft carrying out an instrument approach circling for RWY 25 not to circle left hand

3.2 Noise Abatement Procedures Ohakea:

Except in an emergency or when on an authorised instrument approach procedure under IMC conditions, departing and arriving aircraft are to avoid
overflying SANSON TOWNSHIP (R092/1.5 NM OH VOR/DME) and BULLS TOWNSHIP (R325/2NM OH VOR/DME). To meet this requirement when operating from the most critical runways the following specific procedures are to be adhered to:

Arrival — RWY 15 and RWY 27

•  VFR Flights
• VFR flights are not to overfly SANSON or BULLS TOWNSHIPS
• IFR Flights - When visual, if time permits, IFR flights are to remain visually clear of
  SANSON and BULLS TOWNSHIPS. However, when adverse weather
  conditions exist, no departure from the published instrument approach
  the procedure is expected.

ATC requirement: H24 — all IFR flights cleared at 11,000 ft or above:

• On tracks between radials 215 to 261 (inclusive) Ohakea VOR/DME — maintain 10,000 ft to 60 OH
• On all other tracks — maintain 10,000 ft to 30 OH

Section 4: Ohakea Tower Procedures

4.1 Area of Responsibility:

Ohakea Tower is responsible for all flights within the OH CTR/C, 2,500’ or below.

4.2 IFR Departures:

Ohakea Tower shall request an IFR release from Ohakea for all departures prior to clearing the aircraft for takeoff.

Unless otherwise coordinated, aircraft shall be released on track.

4.3 IFR Arrivals:

Ohakea shall restrict aircraft on a visual approach to 3,000’ unless otherwise coordinated.

Aircraft on an instrument approach may descend below 3,000’ in accordance with the published profile.

4.4 Transfer of Control:

Departures:  3,000’, unless otherwise coordinated
Arrivals:  Within 5 OH DME

4.5 Transfer of Communications:

Departures:  Airborne
Arrivals (on an instrument approach): At 10 OH DME, established on a straight-in approach or following a DME Arc approach; or Beacon outbound, commencing an approach from the overhead.
Arrivals (on a visual approach): 10 OH DME.

4.6 Unattended Procedures:

When Ohakea Tower is offline, the Ohakea Sector or Ohakea Approach is responsible for issuing IFR clearances to departing aircraft.

Section 5: Palmerston North Tower Procedures

5.1 Area of Responsibility:

Palmerston North Tower is responsible for all flights within the PM CTR/D, 1,500’ or below.

5.2 IFR Departures:

Palmerston North Tower shall request an IFR release from Ohakea for all departures prior to clearing the aircraft for takeoff.  Palmerston North Tower shall specify which SID (or other requested departure procedure) the aircraft will be flying when requesting a release.

5.3 IFR Arrivals:

Ohakea shall restrict aircraft on a visual approach to 2,000’ unless otherwise coordinated.  Aircraft on an instrument approach may descend below 2,000’ in accordance with the published profile.

5.4 Transfer of Control:

Departures:  2,000’, unless otherwise coordinated
Arrivals:  Within 7 PM DME

5.5 Transfer of Communications:

Departures:  Airborne
Arrivals (on an instrument approach): At 10 PM DME, established on a straight-in approach or following a DME Arc approach; or Commencing base turn, following an approach from the overhead.
Arrivals (on a visual approach): 10 PM DME.

5.6 Unattended Procedures:

When Palmerston North Tower is offline, Ohakea is responsible for issuing IFR clearances to departing aircraft.
