Limited instrument coverage

Portage Municipal’s instrument set is concentrated on a single RNAV (GPS) approach serving just one of the airport’s four runway ends. The other three ends have no published approach this cycle, and there is no published airport diagram. Runway 18/36 provides the greater available length at 3,770 ft; 04/22 is 1,102 ft shorter, making runway choice material where required take-off or landing distance approaches the available length.

Wider chart context

Nearby procedure coverage varies sharply. Dane County Regional/Truax Field has a much broader chart set, while Sauk/Prairie and Reedsburg Municipal are only slightly less sparse than Portage. Baraboo/Wisconsin Dells Regional and Middleton Municipal/Morey Field sit between those extremes. The Chicago Sectional adds broader visual-navigation and surrounding airspace context absent from the airport’s small instrument set.
