If RVR is U/S you can continue. What did we do before RVR technology was available? Surely attempting the approach and doing the published missed if not visual is still safe. Or is it??
Would be interesting to hear the ops view in this, as it seems this rule would, make alot more aircraft divert before even having a go atleast, Gets expensive diverting. I can understand shooting an approach and diverting, atleast you have tried. But not to try....Of course this depends if previous aircraft were getting in or you are the first cab off the rank.
If RVR is too low for your category, brings to mind the question when do they close the Airport? Do they take into consideration RVR readings .If not they should, if your JARs have it in Balck and White for the Pilot.
But as the previous poster has stated, they dont, they just make the equipement U/S. So if the controllers take the readings with a grain of salt ,maybe the JAA should.
Maybe they should review this ruling , to give the Captain the option. It seems to be too constrictive to me.
