Approach coverage at Newton

Instrument procedures serve both ends of Newton’s single 5,600-foot runway, so coverage is not confined to one arrival direction. The mix spans ILS and localiser capability, two RNAV (GPS) procedures and a VOR procedure. This combines satellite-based and conventional radio-based options, with the ILS providing a precision approach. All charted arrivals ultimately feed the same runway alignment.

Nearby chart context

Ankeny Regional has slightly broader published chart coverage, while Grinnell Regional is close to Newton’s level. Pella, Knoxville and Marshalltown have thinner sets. The Chicago and Omaha sectionals add broad-area VFR context beyond the terminal procedures, showing the field within two adjoining visual-chart regions. They do not provide the dedicated field-layout detail of an airport diagram, and none is published for Newton.
