Oklahoma flying is built around long runways, broad spacing between cities. a large non-towered airport network. The state has 130 public-use airports, but only 10 are towered. That means a pilot can move from airline-style airport procedures to quiet CTAF work in a single leg. KCSM (CLINTON/SHERMAN, BURNS FLAT) is the standout runway field with 13,503 ft, a tower, an ILS. 1 FBO. KTUL (TULSA INTL, TULSA) brings a 10,000 ft runway, ILS capability. 3 FBOs. KOKC (OKC WILL ROGERS INTL, OKLAHOMA CITY) is the more complex airport environment, with 4 runways and 2 FBOs. The smaller fields are just as important for real Oklahoma flying. KPNC (PONCA CITY RGNL, PONCA CITY) is non-towered but has an ILS, a 7,201 ft runway. 1 FBO. KBVO (BARTLESVILLE MUNI, BARTLESVILLE) is another non-towered ILS field with a 6,850 ft runway. Watch wind, summer density altitude. convective weather. The runways are generous in many places, but the weather can still set the limits.
