Yes I’m in EASA land ( well until 29th Mar but that’s a different topic).
Ive heard of the situation of cat3b let’s say AMS 18R you could use 1 RVR on 27 as it’s same Aerodrome.
Thanks I think I now understand the 90m segment.
My ops manual says ‘The touchdown RVR is always controlling for all instrument approaches’. However and this maybe the change that came in a couple years ago it then says ‘If reported and relevant, the mid point and and stop end are also controlling’.
Does this imply if the TDZ rvr is not working then the mid point is now relevant and controlling? So if not using rollout you would need the 125m mid point as this is now controlling. Is this the right logic?
