Why is ADF required on ILS approach?

Wait! He can use a GPS in place of the ADF on that approach. Isn't that
correct?

And the ILS plate is marked ADF required? Why is that?

... because you need to know where the LOM/IAF called LADOS is.

It's an IAF, so there's no previous fix from which you can start timing to
find LADOS.

DME is not required, so you can't assume you can use it to find LADOS -
yes,
even though it's clearly marked 5.2NM on the plate.

If you want to get into ELD without an ADF, you'll have to use one of the
other 3 approaches. Those aren't terrible options.
