I understand how the approach categories are computed (1.3 x Vs0)and understand the logic for the higher mins. as you move to higher categories for circling approaches but I would like more clarity for straight in approaches.
Assume straight in approach and assume a airplane is Cat. A ( using 1.3 Vso ) and I have elected to land straight in with a tailwind (although typically I would not approach or land with a tailwind) .My usual IAP speed is 85 KIAS. The tailwind puts my ground speed at 95 knots yet my indicated is 85 knots. Based upon the categories, 95 knots ground speed puts me in category B but 85 KIAS puts me in category A. Assume the IAP has higher mins. for Cat. B.
QUESTION: Do I use Cat. A or Cat. B mins?
Thank you for the feedback.
