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.


The FAA is a chart maker, the speeds in the timing tables on FAA charts are
ground speed.
