FAAO 8260.19 requires any arcs in a radar environment to be removed
unless they are operationally required. It appears that someone deemed
that they were not needed back in 1992, when they were removed from the
procedure. GPS was overlayed later, so had nothing to do with removal of
the arcs.

The ARCs were, and would be, of significant operational benefit at this location.


The arcs probably had the annotation "NoPT" on them, since a course
reversal would not have been required from the arcs based on the TERPS
criteria in effect back in 1992.

Do you know of any ARC intitial approach segments that require a course reversal? The
ARCs would have certainly had "NoPT" on them with a hold-in-lieu, not "probably."



Since ATC was substituting radar flight following (not vectors) combined
with center's MIA to protect the GPS equipped aircraft on his flight to
MINES, then it would be up to ATC to indicate that the course reversal
was not necessary by stating that to the pilot.

By what authority?
