Here in Europe, flying the A320/A321, we regularly go to "small" airports at holiday destinations where there's no radar but in the summer, 95% of the time it's CAVOK - we do visual approaches: they are taught and practiced in the sim regularly and just require us to stable by 500'aal, otherwise it's a mandatory go-around - never presented any problems.
I aso mixed fleet fly on the A330 as well and we do them on that in the Caribbean!
