A narrowly focused procedure set

Poplar Grove has a single RNAV (GPS) approach, accompanied by the associated minimums document. This gives the field one instrument arrival procedure rather than a choice of approach types, while no airport diagram is published. Of the three runway alignments, 12/30 is both the only asphalt runway and the longest; the two turf runways are shorter by more than 1,000 ft.

Nearby chart coverage

Chicago/Rockford International has the broadest nearby procedure set with 20 charts, followed by Southern Wisconsin Regional with 10. Beloit and Galt Field match Poplar Grove’s two-chart total, while Lake in the Hills has three. The Chicago Sectional and Terminal Area Chart add wider visual and terminal-area context not supplied by Poplar Grove’s single instrument procedure.
