The FAA doesn't provide timing tables in the source. The chart makers do those.
Those are still indicated airspeed. If you choose to convert those values to TAS,
then to G/S, that is your option and is a good operating practice. But, it is not
mandatory, at least not in the sense that courses and altitudes on an IAP chart
are mandatory.

I meant to say if you choose to use those values as G/S and do the necessary
conversions from IAS to TAS to G/S, that is your option and a good operating practice.
