# ANKUB One non-jet departure

> ANKUB One non-jet departure.

## Before departure

ANKUB One is an **RNP 1 departure for non-jet aircraft**. Keep indicated airspeed at or below **250 kt below 10,000 ft**, and at or below **270 kt until NB524**. Both limits apply where they overlap.

There are trees in the departure areas and man-made obstacles in the runway 34R departure area. During parallel runway operations, **do not turn towards the other runway**.

## Initial runway instructions

Fly the initial track below. At the specified altitude, turn onto the assigned heading or track, then expect radar vectors to ANKUB.

| Runway | Initial track | Turn altitude | Required climb gradient |
| - | - | - | - |
| 07 | 062° | 600 ft | 5% to 1,500 ft, then 3.3% |
| 25 | 242° | 800 ft | 3.9% to 300 ft, then 3.3% |
| 16R | 155° | 600 ft | 3.3% |
| 16L | 155° | 500 ft | 3.3% |
| 34R | 335° | 500 ft | 4.8% to 1,500 ft, then 3.3% |
| 34L | 335° | 600 ft | 3.3% |

## From ANKUB to NB524

This sequence is common to both transitions. Distances are for each leg.

| From | Instruction | To | Distance | Crossing requirement |
| - | - | - | - | - |
| ANKUB | Track 277° | IKORO | 6 NM | At or below 5,000 ft |
| IKORO | Turn left, track 261° | NB523 | 14 NM | At or above 9,000 ft |
| NB523 | Turn right, track 282° | NB524 | 5 NM | — |

The required climb gradient **from IKORO to NB523 is 4.9%**. Maintain the 270 kt limit until NB524, including through this sequence.

## KADOM transition

From NB524, turn right onto track **341° to NB540**, a 10 NM leg. At NB540, turn left onto track **269° to KADOM**, a further 10 NM.

## BENBU transition

| From | Instruction | To | Distance |
| - | - | - | - |
| NB524 | Turn right, track 341° | NB525 | 7 NM |
| NB525 | Turn right, track 354° | NB526 | 6 NM |
| NB526 | Turn left, track 310° | DUBSU | 8 NM |
| DUBSU | Turn left, track 304° | BENBU | 32 NM |

## 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 | 120.5 |
| Departure south, west and northwest | 129.7 or 118.4, as assigned |

## 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**.
