# CORRS One jet departure

> CORRS One jet departure.

This **RNP 1** area-navigation departure is for **jets from runways 16, 27 or 34**. Maximum indicated airspeed is **250 kt below 10,000 ft**. The source warns of **trees in the runway 34 departure area**.

## Runway 16

The initial published climb gradient is **3.3%**, with a **6.5% required gradient to YARRA**.

1. Track **160° for 10 NM to YARRA**. Cross YARRA **at or above 4,000 ft**.
2. Turn **left**, track **087° for 36 NM to CORRS**, then continue as cleared.

## Runway 27

The initial published climb gradient is **3.3%**. The chart additionally requires **9.9% to LILPU** and **5.3% to SULPO**.

1. Track **263° for 6 NM to LILPU**. Cross LILPU **at or above 4,000 ft**.
2. Turn **left**, track **200° for 6 NM to DARLY**.
3. Turn **left**, track **105° for 7 NM to SULPO**. Cross SULPO **at or above 8,000 ft**.
4. Turn **left**, track **090° for 41 NM to CORRS**, then continue as cleared.

## Runway 34

The initial published gradient is **4.6% to 1,500 ft, then 3.3%**. The chart additionally requires **7.1% to POREM** and **6.2% to GEDEN**.

1. Track **340° for 4 NM to ROKDL**.
2. Turn **right**, track **015° for 7 NM to POREM**. Cross POREM **at or above 5,000 ft**.
3. Turn **right**, fly **direct to GEDEN**. The chart labels this leg **15 NM**. Cross GEDEN **at or above 10,000 ft**.
4. Turn **left**, track **102° for 31 NM to CORRS**, then continue as cleared.

POREM is drawn as a **fly-over waypoint**; the other named waypoints use fly-by symbols.

## Sector altitudes and chart conventions

The **10 NM minimum sector altitude (MSA) is 3,300 ft**. The **25 NM MSA**, centred on the **YMML aerodrome reference point (ARP)**, is **4,500 ft in the northern sector** and **3,700 ft in the southern sector**. The sector boundaries are labelled **B-080°** on the west side and **B-260°** on the east side; these are bearing labels, not VOR radials.

Tracks are magnetic; altitudes are feet above mean sea level (AMSL), and leg distances are nautical miles (NM). The diagram uses **12° east magnetic variation** and is **not to scale**. **Direct** means fly to the named waypoint without a published magnetic track for that leg.
