Circle Town County has two RNAV (GPS) approaches serving two distinct runway ends, so its small instrument set is not concentrated on a single arrival direction. With no airport diagram or departure procedures published, the cycle is focused narrowly on arrivals and minimums.
The 1,820 ft difference between the runways is consequential: an aircraft requiring more than 2,280 ft has only the 4,100 ft asphalt runway available. Nearby procedure coverage remains similarly compact. Dawson Community and Sidney-Richland Regional have the broadest sets at five charts each, L M Clayton has four, and Poplar Municipal matches Circle Town County’s three. The Billings Sectional adds the broader visual and geographical context absent from the instrument procedures.
