General discussion for aviators

GPS instead of ADF, DME,…

In some other posts, at least one person made comments that
suggest to me that an IFR-certified GPS receiver could be used
in lieu of an ADF even though the approach procedure specifically
states: "ADF-required".  Is this true?  What document(s) are the
basis for this?

Thanks

    Twas me. I got the info from my CFII/Accident Prevention Counselor/Arnav GPS
    owner. A GPS certified for "terminal" can be used to find iaf’s and other
    parts of an approach (but not fly the approach itself – like past the faf
    perhaps). I think this comes from the POH supplement for the GPS receiver/
    installation. Will try to find out more.

    Craig, unless you’re with the NTSB or a professional accident
    reporter, you’ve attended WAY more than your share of accidents.
    The word "jinx" comes to mind.  It’s not that I wouldn’t want to
    meet you, but please don’t visit Houston any time soon.  Oh, and
    I wouldn’t mind if you’d stay away from those Shuttle landings,
    too.  We have a hard enough time landing without engines.

    Now Now, is he a "jinx", or is he an extremely LUCKY person for not
    having been killed in any of these crashes?

    I witnessed my first crash ever at the Concord, NH, airshow last
    summer.  A Steerman with a wingwalker (the pilot’s daughter) crashed
    and burned right in front of me and my 8 year old daughter.  I hope to
    never repeat the experience.
