# Melbourne Six radar departure

> Melbourne Six radar departure.

This radar departure serves **runways 09, 16, 27 and 34**. Maximum indicated airspeed (IAS) is **250 kt below 10,000 ft**. The source warns of **trees in the runway 34 departure area**.

## Initial track and climb

For every runway, turn onto the **assigned heading or track at or above 1,500 ft**.

| Runway | Initial magnetic track | Published climb gradient | Additional gradient printed in parentheses |
| - | - | - | - |
| 09 | 083° | 3.3% | 4.8% to 3,000 ft |
| 16 | 160° | 3.3% | 5.5% to 5,000 ft |
| 27 | 263° | 3.3% | 5.0% to 4,000 ft |
| 34 | 340° | 3.5% to 1,200 ft, then 3.3% | 5.4% to 3,500 ft |

The source presents both gradient sets without explaining the parenthetical convention on this sheet. Both are retained here pending verification of that convention against the applicable AIP legend. The turn altitude and climb-gradient altitude limits are separate values.

## Communications failure

On recognising communications failure:

1. Set the transponder to **7600**.
2. Maintain the **last assigned vector for two minutes**. If necessary, climb to the minimum safe altitude to maintain terrain clearance.
3. Then proceed in accordance with the **latest ATC route clearance that you acknowledged**.

## Navigation reference and sector altitudes

**Melbourne ML VOR/DME is 114.1 MHz**. The **10 NM minimum sector altitude is 3,300 ft**. Within **25 NM of ML VOR**, the northern sector is **4,500 ft** and the southern sector is **3,700 ft**, divided by radials **R-260° on the west side** and **R-080° on the east side**.

Tracks are magnetic and altitudes are feet above mean sea level. The diagram uses **12° east magnetic variation** and is **not to scale**.

## Frequencies

All frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 114.1 or 118.0 |
| Airways clearance delivery | 127.2 |
| Surface movement | 121.7 |
| Tower | 120.5 or 322.4 |
| Departure, tracks north-west, north or north-east | 118.9 |
| Departure, tracks south-west, south or south-east | 129.4 |
