Tillitt Fld is in Forsyth, Montana. Field elevation is 2,729.3 ft MSL. The airport has one runway. Runway 09/27 is 4,799 ft long and asphalt. There is no control tower. CTAF and UNICOM are both 122.8. No ILS approaches are published here.
Pattern altitude is not published. Use 1,000 ft AGL for light piston traffic unless the current Chart Supplement says otherwise. The airport sits in eastern Montana, so density altitude can matter on warm days at this elevation. Plan performance with that in mind. The runway lights on 09/27 are medium intensity. They operate from dusk to 2200. After 2200, lighting activation is by CTAF. The PAPI on both runway ends is also activated by CTAF.
Tillitt Field is the on-field FBO. It carries AVGAS 100LL. If you need anything specific on the ground, call the field at (406) 351-1261. For clearance delivery, contact Salt Lake ARTCC at 801-320-2568. Before a night or IFR arrival, check the current Chart Supplement for any changes to lighting, procedures, or other published remarks.
