Met Vis vs RVR
Can I draw on your collective experience to seek an answer to a question that is bothering me. I operate under JAR Ops rules where it is not permissible to proceed beyond the outer marker if the visibility/RVR is below the appropriate minima.
If Met vis is reported as good (relatively) but the RVRs are below Cat 1 minima (I guess this is caused by a layer of very shallow fog) would it be permissible to ignore the RVRs and continue a Cat 1 approach? [e.g. Met vis 1400m, RVRS 250m/250m/300m, no Cat 2/3 available].
What if the runway environment could be seen from the outer marker?
I suspect there will be many answers, but if anybody can quote a reference from JAROps (or similar) I would be most grateful.
