# MARLN Six arrival

> MARLN Six arrival.

## Arrival to BIKUS

MARLN Six is an **RNP 1 arrival**. Tracking via **RIKNI requires ATC clearance**. The diagram depicts a hold at RIKNI with inbound track **263°** and left turns; it does not print a holding altitude or leg time.

From MARLN, track **264° to BIKUS**, a **14 NM** leg with a charted segment minimum altitude of **1,500 ft**. Cross **BIKUS at or above 8,000 ft**, then follow the branch for the cleared runway.

Distances are for each leg. The segment minimum altitude column reproduces the chart’s route altitude labels; waypoint crossing restrictions are listed separately.

## Runway 25

| From | Track | To | Distance | Segment minimum altitude | Crossing restriction |
| - | - | - | - | - | - |
| BIKUS | 284° | VENUL | 11 NM | 1,500 ft | Between 5,000 ft and 9,000 ft |
| VENUL | 284° | UXAMA | 7 NM | 1,500 ft | — |
| UXAMA | 241° | JELLI | 4 NM | 1,500 ft | — |

From JELLI, follow the cleared **GLS, ILS, RNP or localizer approach to runway 25**.

## Runways 07, 34L, 16L and 16R

| From | Track | To | Distance | Segment minimum altitude | Crossing restriction |
| - | - | - | - | - | - |
| BIKUS | 264° | WHALE | 10 NM | 1,500 ft | At or below 9,000 ft |
| WHALE | 264° | PRAWN | 10 NM | 1,500 ft | At or above 6,000 ft |
| PRAWN | 264° | TESAT | 10 NM | 1,700 ft | — |

Expect radar vectors to final.

## Runway 34R

Follow the same route from BIKUS through WHALE to PRAWN, with the same altitude restrictions. At PRAWN:

1. Turn **left** onto track **187° to MANFA**, a **5 NM** leg labelled with a **1,500 ft** segment minimum altitude. Cross MANFA at **no more than 235 kt indicated airspeed**.
2. Turn **left** onto track **155° to JAKLN**, a **9 NM** leg also labelled **1,500 ft**.
3. Continue on track **155°** and expect radar vectors to final.

During [precision runway monitoring operations](https://www.narev.ai/docs/irl-gym/airports/sydney/charts/precision-runway-monitoring.md), expect to track downwind until reaching **2,000 ft**.

## Approach speeds

Keep indicated airspeed at or below **250 kt below 10,000 ft**, as well as any tighter limit stated on the route. The chart lists these ATC approach speed ranges:

| Distance from touchdown | Indicated airspeed |
| - | - |
| 10 NM | 160–185 kt |
| 5 NM | 150–160 kt |

## Radio failure in instrument conditions

If able, contact Sydney approach on **+61 2 9556 6515**. 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 radio frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 118.55 |
| Approach | 124.4 |
| Director east | 125.3 |
| Director west | 126.1 |
| Tower: runways 16R/34L and 07/25 | 120.5 |
| Tower: runway 16L/34R | 124.7 |
| Surface movement east of runway 16R/34L | 121.7 |
| Surface movement west of runway 16R/34L | 126.5 |

## Sector altitudes and chart conventions

The **25 NM minimum sector altitude is 2,700 ft**, centred on the **YSSY aerodrome reference point**. The **10 NM minimum sector altitude is 2,100 ft**. Bearings are magnetic, with **13° east** variation. Altitudes are feet above mean sea level unless a flight level is stated. These route diagrams are **not to scale**.
