On the ILS, approach straight in to RWY 18L at PIE airport. The approach minimum DA/H is 207 ft and 1800 RVR. ATIS report 200ft Ceiling and ¾ SM Vis. As descending on glide slope, my altimeter reads 207 ft. and I must make my own decision whether to continue the descent and approach, or to execute a missed approach. Beside IFR Takeoff and landing under FAR 91.175 there is anything that I need to take in consideration?
