Some approach plates have published side-step minimums to parellel runways. However, some parallel runways do not have published side-step mins.
1. Can ATC clear you to side-step to a runway that does not have published "side-step" mins?
2. If # 1 is applicable, what is the visibility/ceiling mins. for a side-step approach for which no minimums are published on the approach plate?
3. Why don't all parallel runways have published side-step mins?
