# ISPEG One runway 16 jet departure

> ISPEG One runway 16 jet departure.

This **RNP 1** area-navigation departure is for **jets from runway 16**. Maximum indicated airspeed is **250 kt below 10,000 ft**. The published climb gradient is **3.3%**.

## Departure and radar transition

1. Track **160° for 2 NM to HORSH**, a **fly-over waypoint**.
2. **At HORSH, turn right**.
3. Fly **direct to ISPEG**, approximately **270°**. The chart labels this leg **12 NM**.
4. **At ISPEG, continue tracking 270°**. Expect radar vectors to the cleared route.

## 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.
