# RAZZI One Alpha arrival to runways 16 and 27

> RAZZI One Alpha arrival to runways 16 and 27.

This **RNP 1** arrival uses magnetic tracks and distances in nautical miles (NM). Altitudes are feet above mean sea level. Maximum indicated airspeed (IAS) is **250 kt below 10,000 ft**, with the additional runway-specific speeds below.

The route tables keep **segment minimum altitudes** separate from **waypoint crossing restrictions**. Distances are for each leg.

Cross **RAZZI at or above 10,000 ft**, then follow the branch for your cleared runway.

## Runway 16

Fly **230 kt IAS from LAGUG**, then **no more than 185 kt from BELTA**. The chart’s ATC approach-speed range at **BELTA is 160–185 kt**.

| From | Track | To | Distance | Segment minimum altitude | Crossing restriction |
| - | - | - | - | - | - |
| RAZZI | 319° | MICHM | 12 NM | 3,000 ft | — |
| MICHM | 321° | MOSVO | 8 NM | 3,000 ft | — |
| MOSVO | 323° | OMBAT | 7 NM | 3,000 ft | OMBAT between 6,000 and 8,000 ft |
| OMBAT | 323° | LAGUG | 4 NM | 3,000 ft | — |
| LAGUG | 323° | NEFER | 3 NM | 3,000 ft | NEFER between 4,000 and 6,000 ft |
| NEFER | 248° | BELTA | 7 NM | 3,000 ft | — |

Turn **right at MICHM**, **right at MOSVO** and **left at NEFER**. From BELTA, continue via the cleared [GLS runway 16](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/gls-runway-16.md), [RNP Z runway 16](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/rnp-z-runway-16.md), [ILS-Y/localizer-Y runway 16](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/ils-y-or-loc-y-runway-16.md) or [ILS-Z/localizer-Z runway 16](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/ils-z-or-loc-z-runway-16-part-1.md).

The source labels **MOSVO–OMBAT as 7 NM on this sheet**, but **11 NM on the runway 09/34 sheet**. Both source values are retained pending reconciliation; they are not interchangeable route instructions.

## Runway 27

Fly **230 kt IAS from MICHM**, then **no more than 185 kt from VISAS**. The chart’s ATC approach-speed range at **VISAS is 160–185 kt**.

| From | Track | To | Distance | Segment minimum altitude | Crossing restriction |
| - | - | - | - | - | - |
| RAZZI | 319° | MICHM | 12 NM | 3,000 ft | MICHM at or above 5,000 ft |
| MICHM | 321° | MOSVO | 8 NM | 3,000 ft | MOSVO at or above 3,000 ft |
| MOSVO | 297° | VISAS | 5 NM | 2,000 ft | — |

Turn **left at MOSVO**. From VISAS, continue via the cleared [GLS runway 27](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/gls-runway-27.md), [RNP runway 27](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/rnp-runway-27.md), [ILS-Y/localizer-Y runway 27](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/ils-y-or-loc-y-runway-27.md) or [ILS-Z/localizer-Z runway 27](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/ils-z-or-loc-z-runway-27.md).

The 5,000 ft MICHM and 3,000 ft MOSVO crossing restrictions apply **only to the runway 27 branch**.

## Radio failure in instrument conditions

Set transponder code **7600**. Comply with the vertical-navigation requirements, but **do not descend below the minimum sector altitude**. Follow the latest arrival clearance to the nominated runway, then fly the most suitable approach.

## Frequencies

All frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 114.1 or 118.0 |
| Approach | 132.0 |
| Tower | 120.5 |
| Surface movement | 121.7 |

## Sector altitudes and chart conventions

The **10 NM minimum sector altitude (MSA) is 3,300 ft**. The **25 NM MSA**, centred on the **YMML aerodrome reference point**, is **4,500 ft in the northern sector** and **3,700 ft in the southern sector**. The boundaries are labelled **B-080° on the west side** and **B-260° on the east side**; these are bearing labels, not VOR radials.

The diagram uses **12° east magnetic variation** and is **not to scale**. **YMEN** identifies nearby Essendon Airport.

Chart **MMLSR02-183**, revised **12 June 2025**, from the fixed publication cycle effective **3 September 2026**.
