> OLSEM One jet departure from runway 34R.

## Before departure

OLSEM One is an **RNP 1 departure for jets from runway 34R**. Keep indicated airspeed at or below **250 kt below 10,000 ft**.

During parallel runway operations, **do not turn left**. There are man-made obstacles and trees in the departure area.

## Departure sequence

1. Climb on track **335°**. The required climb gradient is **4.8% to 1,500 ft**, then **3.3%**.
2. At **500 ft**, turn **right** to intercept and follow track **023° to HALAS**.
3. At HALAS, turn **right** onto track **060°** to intercept track **038°**.
4. Follow track **038° to OLSEM**, then continue as cleared.

## OLSEM–Y193–BANDA requirement

For aircraft cleared via **OLSEM–Y193–BANDA**, reach:

| Distance remaining to BANDA | Required flight level |
| - | - |
| By 156 NM | FL180 |
| By 144 NM | FL220 |
| By 110 NM | FL250 |

**Advise ATC if unable to comply.**

## Frequencies

All frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 118.55 |
| Airways clearance delivery | 133.8 |
| Surface movement east of runway 16R/34L | 121.7 |
| Surface movement west of runway 16R/34L | 126.5 |
| Tower | 124.7 |
| Departure north | 123.0 |

## 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**.
