Was down there on Friday, and had a good long talk about this too...
Ceiling was giving BKN025 (not much use when the circling minima is 2450')
We flew down the ILS03 (as it happened we were visual), descended to 1500'aal and then flew a left hand circuit and landed 21. Early configuration, no GPWS of any sort, and ROD of about 900fpm commenced well after we turned base worked out just grand!
The 2500' crossing height at the FAF on the "VOR 21" place just about puts you on a 3.7 slope to the runway.
If the ceiling happened to be below 2500', I'm not sure how you could land 21 if the tailwind on 03 was outside limits as the circling minima of 03 is also 2450' (cat C).....
