Use QNH and CB NDB, 263 kHz. This is a circling approach; no straight-in minima are supplied. Aerodrome elevation is 1,887 ft. Maximum IAS is 185 kt for both initial approach and holding.
Outbound and inbound sequence
From CB NDB, use the 5,100 ft profile reference and fly the category-specific outbound track and time:
The outbound profile shows 5,000 ft, then 4,500 ft at the left reversal onto 171° inbound. Continue inbound to the applicable circling minimum. CB NDB is the missed-approach point. The chart explicitly marks its DME-distance/altitude table not applicable; do not substitute a DME descent table from another approach.
Missed approach
Track 171°. At 3,600 ft, turn left onto 020° and continue climbing to 5,100 ft, or as directed by ATC. Unlike the VOR runway 17 procedure, this sheet does not add a 6 DME condition to the turn.
Holding at CB NDB
Inbound 354°, right turns, one-minute legs, minimum 5,100 ft; no DME limit is printed. The entry-sector diagram labels 104°, 174° and 284°. Separation from R450C is not assured when holding above the minimum altitude.
Circling and alternate minima
Altitudes are feet above mean sea level; heights and visibility reproduce the chart. Visibility is kilometres.
No circling beyond 4 NM west of runway 17/35.
Frequencies
Sector altitudes
The 10 NM minimum sector altitude is 5,100 ft. The 25 NM diagram is centred on CB NDB or VOR: 4,600 ft between B-125° and B-250°, 7,500 ft between B-250° and B-075°, and 5,900 ft between B-075° and B-125°. Retain these bearing labels rather than substituting the radial labels on the VOR chart.
Restricted areas and map conventions
The map labels R450A: surface–3,500 ft, R450B: 3,500–4,500 ft, and R450C: 4,500–8,000 ft. These are vertical limits, not a statement that the areas are active. Bearings are magnetic, with 12° east variation. Elevations are feet above mean sea level. Map scale is 1:500,000, with a 0–5 NM scale bar. The source colour note refers to specification notices; numerical restrictions and minima are reproduced in text here.
Terrain labels
The source labels spot elevations of 2,944; 2,839; 2,880; 3,311; 2,241; 2,289; 2,425; 2,565; 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.
