Yikes I've forgotten something:
say you're on an IFR flight plan and you're doing the NDB ILS DME R/W 26 approach into Luton where the RVR for CAT A is 550m.
Can you always attempt the approach even if the ATIS says that the visibility is less then 550m or the ATIS says the ceiling is less then the Decision Height ?
Any information is appreciated
