While flying an IFR approach in a learjet 45 into KGYY. I received instructions to establish the localizer ILS runway30 circle to land runway12 the wind has made the only ILS runway at KGYY unavailable. The problem is visibility is less than 1/2 mile, clouds OC at 700, and heavy snow. In other words even if I made an ILS approach to land at runway30 I can barely see the runway threshold in time to make it, let alone make an attempt to circle around to land at a perpindicular runway I can't even see. How do I make such an approach? Is there a way to get the ATC to let me land on runway30 instead? Thanks in advance for any advice and please no posts saying "I just land where I want anyway!".

You go missed and fly to an alternate. If you can't keep the runway in sight for the circle maneuver you have to go missed.Also the chart should have published minimums for the circle.Looking at the chart - if you've got 1/2 mile per the weather you cannot do a CTL... you need 1 mile. (it says 1140 - 1) means you can descend to 1140 ft in one mile of vis.

For some reason I thought runway 12 is a completely different runway when it is the reverse of runway 30(Duh!). However there would have been no way I would have been able to keep it in sight in that weather. I guess I should have taken a better look at the minimums on the charts and as soon as I found out they were using 12 instead of 30 on the ATIS with that visibility, found an alternate. Well at least I did this in a sim not real life. I know what to do next time. Thanks for the advice.
