Just look at the NOS charts. Categories are based on IAS. It tells
you that.


Where does it say that? I don't see anything on the IAP that says this.
I've looked in the FARs and AIM (see the initial posting of this thread)
and they simply say "speed" and don't specifically state indicated or
ground speed.


As I said, get out a set of NOS approach charts. It's right there in B
& W.

Actually, it's on page A2. Approach category and the explanation in
reference to Vso

When flying to the MAP from the FAF you have the distance given and
can often use GPS, or DME for the distance to the MAP, but you still
have a time to calculate time (or take it off a chart) and that is
based on a distance which has to be based on ground speed.


Note that I'm not talking about the FAF to MAP times (although this
thread has morphed into that discussion by others). Those times must
be based on ground speed.


They come right out and tell you. It doesn't get much more simple than
that.
