# Canberra RNP W runway 17 (AR)

> Canberra RNP W runway 17 (AR).

This is an **authorization-required RNP approach for CASA-approved operators only**. Use **Canberra QNH** and **Canberra temperature**. The permitted procedure temperature range is **−10°C to +45°C**. The aircraft must support **radius-to-fix (RF) legs**; the curved legs below are defined arcs, not discretionary turns.

Maximum IAS on the initial approach is **210 kt**. Aerodrome elevation is **1,887 ft**, runway 17 threshold elevation is **1,874 ft**, and threshold crossing height is **50 ft**. The final descent path is **3°**.

## Join from TALAG

Cross **TALAG at or above 5,000 ft**. Follow the route below; total distance from TALAG to RW17 is **10.6 NM**.

| Leg | Geometry | Distance | Distance remaining to RW17 at the end |
| - | - | -: | -: |
| TALAG → CB403 | Track 168° | 2.2 NM | 8.4 NM |
| CB403 → CB402 | Right arc, 5.9 NM radius | 1.7 NM | 6.7 NM |
| CB402 → CB401 | Left arc, 5.9 NM radius | 1.7 NM | 5 NM |

The chart specifically requires **RNP 0.7 from CB403 to CB401**. The profile prints a **4,000 ft** step-down limit after TALAG. The approach path reaches **4,600 ft at CB403** before continuing down the 3° profile.

## Path-altitude checks

| Distance or fix | Altitude on the 3° path, ft |
| - | -: |
| CB403, 8.4 NM before RW17 | 4,600 |
| 1 NM before CB402 | 4,370 |
| CB402, 6.7 NM before RW17 | 4,060 |
| CB401, 5 NM before RW17 | 3,520 |
| 3.9 NM before RW17 | 3,180 |
| 3 NM before RW17 | 2,880 |
| 2 NM before RW17 | 2,560 |
| 1.1 NM before RW17 | 2,270 |

These path checks do not replace the crossing restrictions, step-down limits or selected minima.

## Final approach and missed approach

From **CB401**, the final approach fix **5 NM before RW17**, track **168°** to **RW17**, the missed-approach point. The path altitude at CB401 is **3,520 ft**. The chart does not give a separate path-altitude value at RW17 in its distance table.

For a missed approach, track **168° for 3.5 NM to CURTN**, then follow the RNP AR missed-approach track to GEORG and **climb to 5,000 ft**:

| Leg | Published geometry |
| - | - |
| CURTN → CB408 | Right arc, 4 NM radius; 1 NM leg |
| CB408 → CB409 | Left arc, 4 NM radius; 12.6 NM leg |
| CB409 → GEORG | Track 008°; 22.8 NM |

CURTN is labelled the missed-approach holding fix. The plan view marks **maximum IAS 220 kt** at CB409. Fly the loaded missed-approach sequence; the straight 008° segment starts after the arcs.

## Approach lighting note

Runway 17’s precision approach path indicator (PAPI) is shielded **7° to the right** for obstacle clearance. The **left-hand PAPI is not visible closer than 1 NM**. This is a published visibility limitation; it is not a change to the 3° approach path.

## Minima

Altitudes are feet above mean sea level; heights and visibility reproduce the chart’s parenthesized values. Select the minima corresponding to the approved RNP capability.

| RNP | Categories | Minimum altitude, ft | Height, ft | Visibility, km |
| - | - | -: | -: | -: |
| 0.3 | A–D | 3,180 | 1,306 | 5.0 |
| 0.11 | A–D | 2,270 | 396 | 2.2 |

**Circling is not authorized.** The alternate row gives height–visibility pairs: **A/B 1,863 ft–4.4 km**, **C 2,093 ft–6.0 km**, **D 2,233 ft–7.0 km**.

## Frequencies

| AWIS, after hours | 116.7 MHz |
| Surface movement / airways clearance | 121.7 MHz |
| Tower | 118.7 MHz |
| Approach | 124.5 MHz |

| CTAF + AFRU, after hours | 118.7 MHz |
| AFRU + PAL, after hours | 118.7 MHz |

## Sector altitudes and map conventions

The **10 NM minimum sector altitude is 5,100 ft**. The 25 NM diagram names the **YSCB aerodrome reference point** and uses the printed labels **R-305°, R-070° and R-255°**. The northern/eastern sector between R-305° and R-070° is **4,600 ft**; the southern sector between R-070° and R-255° is **7,500 ft**; the western sector between R-255° and R-305° is **5,900 ft**. These are the chart’s labels, retained without changing the stated centre.

Bearings are magnetic, with **12° east** variation. Elevations are feet above mean sea level. The map scale is **1:500,000**, with a **0–5 NM** scale bar. R450A, R450B and R450C are marked west of the airport; their vertical limits are not printed on this sheet. The [RNP Z runway 35 reference](https://www.narev.ai/docs/irl-gym/airports/canberra/charts/rnp-z-runway-35.md#restricted-areas-shown) includes those limits from its source chart.

The source’s colour note points to chart specification notices. Approach tracks, requirements, altitudes and minima are provided in text here; terrain shading and obstacle positions still require text coverage.
