The extras you mention are optional, not a requirement as per CAP168, Aerodrome licencing. Visual runways are quite common for "cross" runways, ie. not the principle. You can have any IAP you want to them, however the minima will only be at or above the aerodromes VMC/circling minima. Hence the IAP's are considered cloud breaks, which happen to point you in the right general direction for the runway, but will not allow you to decend lower IMC, where you would require the protection of an instrument strip and associated transitional slopes. By only getting a visual licence for the runway you save the cost of requiring PAPIS, etc. and allow aerodrome developements which would infringe the instrument protective area. Is this clear enough??
