Ohio flying is defined by a dense public-use network, 151 airports with 14 towered fields. The state works well for private, charter or training operations because pilots can choose between large controlled airports and many smaller community fields. KLCK (Rickenbacker Intl) sets the runway standard with 12,103 ft at Columbus. KDAY (James M Cox Dayton Intl) adds a 10,901 ft runway with two FBOs. KLUK (Cincinnati Muni/Lunken Fld) gives Cincinnati a lower-elevation urban field at 482 ft. Controlled fields are concentrated around the largest city pairs. KCMH (John Glenn Columbus Intl); KCLE (Cleveland-Hopkins Intl); KTOL (Eugene F Kranz Toledo Express) all provide tower service, ILS, long runways and multiple FBO choices. The north coast has a different feel at KBKL (Burke Lakefront), where the airport elevation is 584 ft and the runway is 6,604 ft. That field deserves extra weather attention because of its Cleveland waterfront setting. Outside the bigger airports, Ohio remains mostly non-towered. The data lists 137 non-towered airports, so CTAF discipline and current Chart Supplement review matter on ordinary cross-countries. KOSU (Ohio State University) has four runways, the most at one Ohio field. Dayton leads the state by airport count with seven public-use fields. That density gives pilots many choices near KDAY, but it also rewards careful identifier, fuel and runway planning.
