I see
So why sometimes they publish CMV instead of VIS? So far I assume that RVR is reported only up to RVR1500 and lets say 1600 will be reported as CMV1600.
So why in EGHG 16-1 in straight-in landing rwy 09 W/o DME we can see CMV 3000m but in circle to land there is VIS 1500 instead of CMV?
And another question according EGHG. What about minimums for airplanes not capable of CDFA (for example C172)? Is it legal to proceed through stepdown DME fixes or do they need to apply minumums only for W/o DME?
