GlobalNav:
I don't know about other countries, but the FAA allows an NPA such as BHM LOC 18 the be flown by non-GPS augmented airplanes 365 days of the year, weather and wind permitting.
Indeed they do. But, more and more they are requiring the VGSI be in sight at night prior to leaving MDA. It's all about obstacles in the FAA-defined visual segment.
