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?
Mooney - If reported, the Mid and End are also controlling - this is IN ADDITION TO the TDZ. TDZ is the primary factor, if you have others available then they too need to be legal if stated (rolling or END are not always so). Think about representing yourself in court when something went wrong during the landing - if you used an RVR other than the point you wanted the aircraft to touchdown would that be sensible or stand the scrutiny of a team of barristers?
Good questions, this is what the forums should be about
