RWY 17

ST THOMAS MUNI (4S5) sits in St Thomas, North Dakota. Field elevation is 839 ft MSL. The airport has one runway, 17/35, which is 2,600 ft long and asphalt. There is no control tower. CTAF is 122.9. No ILS approaches are published here.

Pattern altitude is not published. Use 1,000 ft AGL for light piston operations unless the current Chart Supplement says otherwise. That puts the pattern at about 1,839 ft MSL. The published remarks call out deer and birds on and near the airport. They also note turbulence on crosswind landings for runway 17/35 because of tree lines. That matters here. Expect a tighter feel than a larger field.

Runway 17 and runway 35 both have displaced thresholds marked with green lights for night use. There is also a road close to each end. The runway 35 end has a road 20 ft from the threshold. The runway 17 end has roads near the threshold and displaced threshold. A tree line near runway 35 and another near runway 17 penetrate the transitional surface. No on-field FBOs are listed. Check with the airport operator or the FBO directly by phone for current services before you go. For clearance delivery, contact Minneapolis ARTCC. Confirm winter conditions and snow removal before a cold-weather arrival.
