When the tailwind significantly changes the ETE, on what basis would a
pilot be
able to predict what ATC might "expect"?


None.



I agree with a previous poster that IF the pilot has already been talking
with
Approach and has received a vector toward an IAF or ILS intercept, it is
reasonable to expect to commence approach on arrival. However, what if
comm is
lost on a center freq, in IMC and relatively near the destination? What
is a
"reasonable" time to be holding over the IAF, from the ATC perspective?


None.
