Narrative:

Inbound to tulsa international the airport went WX of with RVR reported as 1200/1800/1000. As I was starting the approach (vectors to 11) I was asked if I was catii and replied in the negative. The rvrs were then reported as 1000/800/800. I shot the approach and landed without incident. After landing company pilots informed me that I had just landed below mins. I am a relatively new part 135 pilot and forgot that 1800 RVR was necessary to commence an approach. The fog was only about 300 ft thick and the rabbit was visible at approximately 1 mi on final. Confusing some of the regulations, I considered this as runway environment and continued to land. Correction: learn the regulations as they apply to your operation.
