Is there a search tool I could use to find the closest SDF, LDA and LOC-BC
approaches? With airnav I can only search for precision or nonprecision
approaches. I am looking for examples of the other less common approaches
that are nearby without having to sift through every page of the approach
book.

Download the NACO volume from the new NACO approach chart site that covers
your area You will then have a searchable PDF file.
