When do I have to slow to approach speed in order to qualify for a particular category? Specifically, if I want/need cat A minima, what is the exact point at which I need to be at 90 kt (or less)?
I’d assumed it was the FAF, because I can’t see how anything before that should affect your minima. My usual CFII says it’s the IAF, and another CFII says 3 miles before the FAF, but neither could cite a rule to support their position; it was just what their CFII had taught them.
(For the sake of argument, assume no legs are marked with explicit category restrictions, as I’ve seen on some teardrop procedures.)
