Can the approach be flown leagally by requesting alternate

Now that's a great question. I suppose ATC can override anything
really.

There is no situation where the plate says ADF required that GPS
cannot
substitute. And yes ATC can come up with alternate missed
instructions.

Um, filing that airport as the alternate (when you are required to have
an
alternate) (assuming it is the only approach) and you do not have an ADF
is
one example I can think of.

Hmmm, I have a problem with this. Aren't you risking a slap on the wrist
if
you file an airport as an alternate KNOWING that you didn't have the
required equipment to begin with. Not to mention that you are playing with
your next birthday. Note, I'm not talking about an enroute failure of the
instrument.


I am not sure you understood my point. The poster I replied to says an IFR
GPS can replace ADF any time. I suggested that is not the case.
Specifically, filing for an alternate that has an approach that says "ADF
required" when you do not have an ADF installed (even if you have a gps) and
there are no other approaches suitable is not legal. You can't substitute
GPS for ADF for an alternat apprch. (filed)

I think you have come to the same conclusion, though not in the same way?

Well, in did misunderstand your point -- but, now that you've clarified
it, I disagree. My interpretation is that an IFR approved GPS will stand in
for the ADF "at any time." (Quote marks are mine for emphasis.) In other
words, if the airplane is IFR GPS equipped, it does not need an ADF for that
alternate to be valid when filing the flight plan.
I got the impression that the pilot intended to file with a known faulty
ADF and no GPS with the intention of requesting a modified missed-approach
for the alternate -- if he needed to go there.
I'm probably reading into the subject. We need a FSDO to answer this
one.

Earlier mention of hanging an 'inop' sticker reminded me of
an occasion back around '70 when we had to inop the ADF
on either a DC8 or 727. Somebody asked if they really needed
an ADF? One of the old timers wisecracked, "How else can
they learn the scores of the ball games."

Oddly enough, about a month later the company started a project
where we installed some wires and installed a switch on the S/O's
panel through out our fairly large fleet. With a flip of this switch
all of the passengers back in the cabin could listen to anything
dialed into the S/O's audio panel. Just in time for the World Series.
