Why is ADF required on ILS approach?

You're viewing the note "ADF REQUIRED" as having legal authority. I view
it
as just a reminder that ADF is needed to fly the full approach, the missed
approach segment in this case. This isn't the first time this matter has
been discussed in this forum. As I recall from previous discussions,
nobody
was able to present any definitive documentation in support of either
view.
But logic tends to support the view that these notes are just reminders to
the pilot. Take a look at most LOC BC approaches and you'll find a
similar
note that says "BACK COURSE". Is that a legal requirement that a back
course receiver must be aboard to fly the approach, or is it just a
reminder
of reverse sensing?


Of course its a requirement, that's why the word "required" is used. You
can use a GPS in substitute, but one or the other is required. "Radar
required" is also a frequently found note. Do you think that if the radar
is inop that day you can still shoot the approach because it was "just a
reminder"?
