# GLS approach to Sydney runway 34R

> GLS approach to Sydney runway 34R.

## Set up the approach

Select **GLS channel 22379**, identifier **G34B**, with final course **335°**. Distances are to **RW34R**, the runway threshold.

## Final approach

The profile shows an initial **2,000 ft** level segment through **ENDEV**, **12.8 NM from the threshold**. Follow the **3° glidepath** through **OLSOG**, **4.8 NM from the threshold**, at a path altitude of **1,600 ft**. The chart gives a threshold crossing height of **50 ft**.

**BOBIG is 8.1 NM from the threshold**, between ENDEV and OLSOG.

## Speeds and holding

Cross **BOBIG at no more than 185 kt indicated airspeed**. Cross **OLSOG at no less than 150 kt indicated airspeed**. The ATC approach speed ranges are **160–185 kt at BOBIG** and **150–160 kt at OLSOG**.

Holding is as advised by ATC.

## Descent checks

| Distance to runway threshold | Altitude on the 3° path |
| - | - |
| 6.1 NM | 2,000 ft |
| 5 NM | 1,660 ft |
| 4.8 NM | 1,600 ft |
| 4 NM | 1,340 ft |
| 3 NM | 1,020 ft |
| 2 NM | 700 ft |
| 1.2 NM | 460 ft |
| 1 NM | 380 ft |
| 0.5 NM | 220 ft |

## Straight-in minima

These minima apply to categories **A, B, C and D**. Heights are above threshold; runway visual range (**RVR**) is in metres.

| Required missed-approach climb gradient | Decision altitude | Height | Visibility / RVR |
| - | - | - | - |
| 4.8% | 220 ft | 207 ft | 1.2 km / 1,000 m RVR |
| 2.5% | 460 ft | 447 ft | 2.2 km |

The lower GLS decision altitude requires a **4.8% missed-approach climb gradient**. Use the row whose requirements can be met.

## Missed approach

Track **direct to SSYST**, **2 NM beyond the threshold**. Turn **right**, direct to **SSYSH**, then track **060°**. Climb to **4,000 ft**, or as directed by ATC. Keep indicated airspeed at or below **185 kt until SSYSH** and meet the missed-approach climb gradient for the selected minima. No distance to SSYSH is printed on this sheet.

## Parallel approaches

Sydney has **closely spaced parallel runways**. Simultaneous approaches are authorized with runway **34L** under the [precision runway monitoring instructions](https://www.narev.ai/docs/irl-gym/airports/sydney/charts/precision-runway-monitoring.md). **Dual VHF communications are required during PRM operations**. Transmit on tower and monitor both tower and PRM frequencies listed below. Aircraft may be radar vectored to final approach.

## Circling and alternate minima

**Circling is not authorized.**

| Category | Alternate ceiling | Alternate visibility |
| - | - | - |
| A and B | 1,269 ft | 4.4 km |
| C | 1,479 ft | 6.0 km |
| D | 1,479 ft | 7.0 km |

## Frequencies

All frequencies are MHz.

| Service | Frequency |
| - | - |
| ATIS | 118.55 |
| Approach north | 124.4 |
| Approach south | 128.3 |
| Director east | 125.3 |
| Director west | 126.1 |
| PRM | 133.95 |
| Tower | 124.7 |
| Surface movement east of runway 16R/34L | 121.7 |
| Surface movement west of runway 16R/34L | 126.5 |

## Terrain and chart conventions

Use **QNH**. Bearings are magnetic, with **13° east** variation. Altitudes and elevations are feet above mean sea level unless identified as radio-altimeter readings or heights. The map scale is **1:500,000**. Aerodrome elevation is **21 ft**; runway 34R threshold elevation is **13 ft**.

The **25 NM minimum sector altitude is 2,700 ft** and the **10 NM minimum sector altitude is 2,100 ft**, centred on the **YSSY aerodrome reference point**.

The map labels obstacle and spot elevations of **160, 190, 250, 255, 299, 306, 320, 385, 389, 421, 426, 430, 545, 641, 677, 725, 862, 887, 894, 1,001, 1,074 and 1,085 ft**. Their geographic placement still requires a complete text description.
