# ILS or localizer approach to Sydney runway 07

> ILS or localizer approach to Sydney runway 07.

## Set up the approach

Use **ISY ILS/DME, 109.9 MHz**, with final approach course **062°**. The ILS requires **DME or GNSS**; a localizer-only approach requires **DME**. The GURSI transition requires **RNP 1**.

**ISY DME and threshold distance are different.** The threshold is at **0.2 ISY DME**. GURSI is at **14.6 ISY DME / 14.4 NM to threshold**, ANKUB at **9.9 / 9.7 NM**, and VIDIK at **4.1 / 3.9 NM**.

## From GURSI to final

1. Cross GURSI **between 4,000 ft and 7,000 ft**.
2. Track **061° to ANKUB**, a **4.7 NM** leg. The profile gives **3,000 ft** for the level segment into ANKUB; cross ANKUB **at or above 3,000 ft**.
3. Follow final course **062°**. The ILS glidepath is **3°**, with a reference datum height of **51 ft**.

## ILS descent checks

These are altitudes on the chart’s 3° path, referenced to **ISY DME**.

| ISY DME | Path altitude |
| - | - |
| 9.4 NM | 3,000 ft |
| 9 NM | 2,880 ft |
| 8 NM | 2,560 ft |
| 7 NM | 2,240 ft |
| 6.4 NM | 2,050 ft |
| 6 NM | 1,920 ft |
| 5 NM | 1,600 ft |
| 4.1 NM, VIDIK | 1,320 ft |
| 3 NM | 970 ft |
| 2.4 NM | 770 ft |
| 2 NM | 650 ft |
| 1.9 NM | 600 ft |

## Localizer-only descent

After ANKUB, observe the following minimum altitudes until reaching each distance. The 3° path values above are descent checks, not substitutes for these step-down restrictions.

| Segment ending at | Minimum altitude on the segment |
| - | - |
| 6.4 ISY DME | 2,000 ft |
| 4.1 ISY DME, VIDIK | 900 ft |
| 2.4 ISY DME | 700 ft |
| From 2.4 ISY DME to the missed approach point | 600 ft minimum descent altitude |

The localizer missed approach point is **0.7 ISY DME**, or **0.5 NM before the threshold**.

## Straight-in minima

The chart applies these minima to categories **A, B, C and D/DL**.

| Approach | Minimum altitude | Height | Visibility |
| - | - | - | - |
| ILS | Decision altitude 216 ft | 200 ft above threshold | 1.5 km; chart specifies 1,500 m RVR |
| Localizer | Minimum descent altitude 600 ft | 579 ft above aerodrome | 3.3 km |

A special alternate minimum of **700 ft / 2.5 km** is printed. It **does not apply to the localizer/DME approach**.

## Missed approach

Track **062°** and climb to **3,000 ft**, or as directed by ATC.

## Speed limits and holding

Cross **GURSI at no more than 210 kt indicated airspeed** and **ANKUB at no more than 185 kt**. The ATC approach speed ranges are **160–185 kt at ANKUB** and **150–160 kt at 5 NM from touchdown**. Holding is **as directed by ATC**; no holding pattern is specified on this chart.

## Circling and alternate minima

Do not circle **beyond 3 DME from SY, east of runway 16R and north of runway 25**. The distance for this restriction is from **SY DME**, not the runway threshold or the approach’s distance reference.

| Aircraft category | Circling minimum altitude | Height above aerodrome | Visibility | Alternate ceiling / visibility |
| - | - | - | - | - |
| A and B | 790 ft | 769 ft | 2.4 km | 1,269 ft / 4.4 km |
| C | 1,000 ft | 979 ft | 4.0 km | 1,479 ft / 6.0 km |
| D/DL | 1,000 ft | 979 ft | 5.0 km | 1,479 ft / 7.0 km |

## Frequencies

All radio frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 118.55 |
| Approach north | 124.4 |
| Approach south | 128.3 |
| Director east | 125.3 |
| Director west | 126.1 |
| Tower | 120.5 |
| Surface movement east of runway 16R/34L | 121.7 |
| Surface movement west of runway 16R/34L | 126.5 |

## Terrain and chart conventions

Use **QNH**. Altitudes and elevations are feet above mean sea level; tracks are magnetic. The chart shows **13° east** magnetic variation and a **1:500,000** map scale. Aerodrome elevation is **21 ft** and runway 07 threshold elevation is **16 ft**.

The **25 NM minimum sector altitude is 2,700 ft** and the **10 NM minimum sector altitude is 2,100 ft**, both centred on the **YSSY aerodrome reference point**. Nearby aerodrome labels on the map are **YSBK, YFIW and YSHW**.

The map’s labelled obstacle and spot elevations are **160, 190, 250, 255, 259, 273, 299, 306, 320, 385, 389, 421, 430, 545, 641, 677, 725, 820, 870, 887, 894, 1,001, 1,074 and 1,085 ft**. Their geographic placement still requires a complete text description.
