Jack,
The 23R ILS is currently withdrawn because the equipment is being replaced. The standard approach to 23R for the next 2-3 weeks is the VOR/DME procedure which requires aircraft to establish on a radial from the 'MCT' beacon, at a slight offset to the centreline, bringing them to a point where they intersect with the extended runway centreline and continue visually. There is no guidance as to the descent profile other than the procedure 'plate' until the PAPIs can be seen and followed. This is a 'non-precision' approach with higher weather minima than ILS. Looks a bit strange when you are used to seeing the stable and straight-in ILS approach.
