Further to the original question, if "the other end" is "Special VFR" you would have to consider the alternate requirements which, for a helicopter able to use Helicopter VMC at its destination, are 1000ft ceiling and vis 3km. That brings to mind the age old question (and argument) of what constitutes a suitable alternate for a helicopter in these circumstances? Whereas aeroplanes must have an alternate which itself does not require an alternate, it could be argued that a helicopter's alternate might be anywhere underneath it suitable for a safe landing. I dunno the real answer to that but in forty odd years of doing it now, common sense has always been the solution for me at the end of the day!
