What values will I use for circle-to-land in categories A and B? RVR 1800m or RVR 2200m? And if I am using them, why are the visibility values such as 1500m-1600m determined?
Before you can do a circling approach, you must do either a either CDFA straight in, or a non-CDFA approach to runway 22, and then circle to land on a different runway.
The circling minimum are dependant on which straight-in approach you conduct, and also dependant on the availability of ALS lighting:
