procedure. Please tell me that he was misinterpreting a rule that said

The restriction is on what may be *filed* as an alternate airport. There
is no restriction on what approaches are actually flown, or how you
navigate.

You are correct. The safety counsellor is confused.

No, he is not if he says you can use the GPS if it is still working, but
you have to have the overlay ground equipment available in case the GPS
goes TA.

Why don't you try reading the original article? The safety counsellor
said that you couldn't use the GPS to navigate the missed approach at the
alternate EVEN IF IT'S WORKING!

you have to be *able* to navigate the missed approach procedure without
GPS, but you don't *have* to do so. So, for instance, if the missed
approach involves holding at a NDB, you have to have a ADF in the plane in
case GPS isn't working, but if the GPS is there and working you can use
it?

I posted a reply to this before but it got lost in the bit bucket.

He is speaking of an overlay approach and he is correct, technically you
must have the underlying equipment available. By the time you get to
the alternate your options are quite limited in any case.

Why don't you try reading what was written right there in front of you?
He didn't say you needed the ground equipment to be available, he said you
must use it, and couldn't use the GPS even if you went missed because of
weather or other non-GPS/RAIM related reasons.
