# Canberra RNP runway 30

> Canberra RNP runway 30.

This is an **RNP approach** with **LNAV minima for categories A and B**. The minima panel marks categories **C and D not applicable**. **Use QNH.** Aerodrome elevation is **1,887 ft** and runway 30 threshold elevation is **1,884 ft**.

## Initial approach

Cross the assigned initial fix at or above **7,500 ft**, then fly to **CB2EI**, the intermediate fix:

| Initial fix | Track to CB2EI | Distance |
| - | -: | -: |
| CB2EA | 227° | 7 NM |
| CB2EB | 297° | 7 NM |
| CB2EC | 007° | 7 NM |

Each initial fix is **18 NM along the procedure before CB2EM**, the missed-approach point. From CB2EI, track **297° for 5 NM to CB2EF**, the final approach fix, then continue **297° for 6 NM to CB2EM**.

## Final profile and distance references

The descent-path reference is **3.7°**. It **does not coincide with the runway PAPI glide-slope indication**. Keep the published path and altitude limits together instead of treating the PAPI as confirmation of this path.

| Position before CB2EM | Profile minimum |
| - | -: |
| Initial fix, 18 NM | 7,500 ft |
| Initial segment toward CB2EI | 5,400 ft |
| CB2EI, 11 NM | 4,300 ft after the fix |
| 7 NM | 3,900 ft |
| CB2EF, 6 NM | 3,200 ft after the fix |
| 3.5 NM | 2,900 ft |
| 2.5 NM | Continue to the 2,780 ft LNAV minimum |

The threshold lies **0.3 NM beyond CB2EM** on the inbound path. The plan view also marks **1 NM**, **2.5 NM** and **3.5 NM** before CB2EM.

These are the chart’s path-altitude checks:

| Distance before CB2EM | Path altitude, ft |
| - | -: |
| 1.8 NM | 2,780 |
| 2 NM | 2,840 |
| 3 NM | 3,230 |
| 4 NM | 3,630 |
| 5 NM | 4,020 |
| CB2EF, 6 NM | 4,410 |

Before CB2EF, the distance reference changes:

| Distance before CB2EF | Path altitude, ft |
| - | -: |
| 1 NM | 4,800 |
| 2 NM | 5,200 |
| 3 NM | 5,590 |
| 4 NM | 5,990 |
| CB2EI, 5 NM | 6,380 |

The profile additionally labels **3,040 ft at 2.5 NM** and **3,430 ft at 3.5 NM before CB2EM**. Path altitudes are separate from the lower step-down limits.

## Missed approach

At CB2EM, **turn left and track direct to CB2EH**, then track **140°** and **climb to 7,500 ft**. Maximum IAS during the missed-approach turn is **150 kt**. The diagram labels the direct leg to CB2EH **189° / 5.7 NM**. CB2EH is the missed-approach holding fix.

## Holding at CB2EB

Inbound **297°**, **left turns**, **one-minute legs**, minimum **7,500 ft**. No DME limit is printed. Entry-sector labels are **117°, 187° and 007°**.

## Minima

| Procedure | Categories | Minimum altitude, ft | Height, ft | Visibility, km |
| - | - | -: | -: | -: |
| LNAV | A and B | 2,780 | 893 | 4.2 |
| Circling | A and B | 3,350 | 1,463 | 2.4 |
| All minima | C and D | Not applicable | — | — |

The LNAV height **893 ft** is the value printed in the chart; it uses the aerodrome elevation rather than the 1,884 ft threshold elevation. Alternate height–visibility for A/B is **1,963 ft–4.4 km**. **No circling beyond 4 NM west of runway 17/35.**

## Sector altitudes and chart conventions

The **10 NM MSA is 5,100 ft**. The 25 NM diagram is referenced to the **YSCB aerodrome reference point**: the northern/eastern sector bounded by chart bearings **B-125° and B-250°** is **4,600 ft**, the southern sector between **B-250° and B-075°** is **7,500 ft**, and the western sector between **B-075° and B-125°** is **5,900 ft**. These are the bearing labels on the ARP diagram, not CB VOR radial labels.

Tracks are magnetic, elevations are feet AMSL, and distances in parentheses are NM. The map shows **12° east** magnetic variation and a **1:500,000** scale with a **0–5 NM** bar.

The map labels R450B **3,500–4,500 ft** and R450C **4,500–8,000 ft** west of the airport. These vertical limits do not establish current activation. The source colour note refers to specification notices; the numerical approach requirements are given above.

## Terrain labels

The source labels spot elevations of **2,944; 2,839; 2,880; 3,311; 2,241; 2,289; 2,425; 2,506; 3,020; 2,226; 2,667; 2,810; 2,604; 2,641; 3,245; 3,543; 3,344; and 3,671 ft**. Their geographic positions and obstacle symbols have not yet been fully transcribed into this text.
