# ALAXO One Papa arrival to runway 16

> ALAXO One Papa arrival to runway 16.

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.

The chart depicts a **right-turn hold at ALAXO with inbound track 064°**. It does not print a holding altitude or leg time.

## Route to EMSEK

| From | Track | To | Distance | Segment minimum altitude | Crossing restriction |
| - | - | - | - | - | - |
| ALAXO | 070° | IKUNA | 23 NM | 3,100 ft | IKUNA at or above 9,000 ft |
| IKUNA | 069° | KEELA | 16 NM | 2,100 ft | KEELA at or above 6,000 ft |
| KEELA | 070° | PASCO | 8 NM | 2,100 ft | PASCO at or above 5,000 ft |
| PASCO | 345° | EMSEK | 5 NM | 2,400 ft | — |

Turn **left at IKUNA** and **left at PASCO**. Fly **230 kt IAS from PASCO**.

From EMSEK, continue via [RNP P runway 16 (AR)](https://www.narev.ai/docs/irl-gym/airports/melbourne/charts/rnp-p-runway-16-ar.md). **AR means authorization required**; the arrival’s RNP 1 specification does not by itself provide the approach authorization.

## 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 | 129.4 or 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.
