Fairfield/Frostenson Airfield sits near Fairfield, Idaho. Field elevation is 5,058 ft MSL. The airport has one runway. Runway 08/26 is 2,950 ft long and surfaced with dirt. There is no control tower. CTAF is 122.9.

No ILS approaches are published here. Pattern altitude is not published, so use the standard 1,000 ft AGL pattern unless the current FAA Chart Supplement says otherwise. That puts the light piston pattern at about 6,058 ft MSL based on the field elevation. The airport is high enough that density altitude will matter on warm days. Expect performance to be a real factor.

Published remarks call out irregular winter maintenance. Check runway condition with the airport manager before use. The runway ends also have nearby obstructions. At the 08 end there is a 15-foot road 100 feet left of the runway end. At the 26 end there are numerous obstructions within 300 feet of the runway end. There is also a 15-foot road 100 feet right of the runway end plus a 35-foot power line 100 feet from the end, 75 feet right. For clearance delivery, contact Salt Lake ARTCC at 801-320-2568. No on-field FBOs are listed, so verify services with the airport operator or the FBO directly by phone before you go.
