Runway 04/22 is not nominated by default and is only available on request or when operationally required for emergencies. Requests for Runway 22 may be granted if traffic conditions allow. Runway 04 is less likely to be approved due the need to vacate onto an intersecting runway.

## VFR Inbound Procedures

Aircraft should report at the standard VFR entry points:
- **BTO** (to the north)
- **BAW** (to the west)
- **CARR** (to the southwest)
- **GMH** (to the southeast)
- **ACE** (to the northeast)
- **SHOAL** (to the southwest)

Circuit join instructions are determined case by case based on traffic management and pilot position. The most common joins are listed below:
| Direction from YMMB | Entry Point |
|-------------|----------------------|
| North | BTO |
| North East | ACE |
| East | GMH |
| South | CARR |
| South West | SHOL |
| West | BAW |

### Departures

Day VFR helicopter departures must remain at or below `A007`. Helicopters must nominate a aiming point, eastern grass, western triangle or HLS on first contact with MB ADC.

- **Aiming Points**:
- Direct helicopters departing from the **Southern Aiming Point** to hold short of **TWY A**.
- Direct helicopters departing from the **Northern Aiming Point** to hold short of **TWY G**.

- **Departure Procedures**:
- Departures should remain clear of duty runways and:
- **Track**:
- For **northbound departures**: Track north until clear of the tower.
- For **southbound departures**: Track south until clear of airport buildings.

VH-RJB, an R44 helicopter, is looking to depart to the north towards essendon VFR. 17L/R is active.

!!! tip
Remember you can have helicopters report at key locations as memory aid.

### Arrivals

- ML TCU will heads-up coordinate arrivals/overfliers from Class C to MB ADC.

- **From the East**:
- Helicopters arriving from the east should be instructed to fly a close base leg and pass over the duty threshold at **not below `A003`**.
- For duty runways **13** or **17**, helicopters arriving for the northern or main aprons may be instructed to overfly the duty threshold at **not below `A003`** for a short right circuit.
- For **circuits**, helicopters arriving may directly join a leg of the circuit.

- **From the West**:
- For **southerly approaches** full stop: Instruct helicopters to remain clear of duty runways, track east of the tower, and proceed directly to the **Southern HLS** or southern aiming point.
- For **northerly approaches** full stop: Instruct helicopters to remain clear of duty runways, track east of the tower, and proceed to the northern or main aprons.
- For **circuits** have the aircraft fly overhead the tower and report. Instruct the aircraft to join a leg of the circuit.

!!! phraseology
VH-RJB, an R44 helicopter, is looking to join the circuit from the west at Cerberus, with runway 17L/R active.

**RJB**: "Join downwind runway, 17R"

## Coordination

### Departures
When the aircraft is ready for departure, MB ADC will coordinate with the relevant ML TCU controller above them for permission to release the aircraft into their CTA.

- Autorelease is not in effect. Coordination for "Next" is required required for departures into overlaying Class C. They must not be issued a takeoff clearance until a release has been obtained.
- Standard assignable level: `A050` (or `RFL` if lower).

<span class="hotline">**MB ADC** -> **MDS**</span>: "Next, SGE"
<span class="hotline">**MDS** -> **MB ADC**</span>: "SGE, unrestricted"

Aircraft departing directly into Class C airspace should be instructed to report passing A025 and transferred to the TCU at that point.

!!! phraseology
**SGE**: "SGE, A025"
**MB ADC**: "SGE, contact Melbourne Departures on 129.4"
The Standard Assignable level from MB ADC to ML TCU is the lower of `A050` or the `RFL`, any other level must be prior coordinated.

Aircraft who will transit Class G airspace on climb into CTA will be **cleared to leave and re-enter controlled airspace** on climb to their assigned level.
Aircraft who will transit Class G airspace on climb into CTA must be **cleared to leave and re-enter controlled airspace** on climb to their assigned level.

- ML TCU will heads-up coordinate arrivals/overfliers from Class C to MB ADC.
- **IFR arrivals** will be cleared for the coordinated approach (Instrument or Visual) prior to handoff to MB ADC, unless MB ADC nominates a restriction.
- **VFR arrivals** will not be coordinated, and will need to receive their airways clearance from MB ADC.
