RWY 09

Southwest Wyoming Rgnl Airport sits in Rock Springs, Wyoming. The field elevation is 6,764.6 ft MSL, so performance planning matters here. The airport has two asphalt runways. The longest is 09/27 at 10,002 ft. Runway 03/21 is 5,228 ft. There is no control tower. CTAF and UNICOM are both 122.8.

An ILS approach is available to runway 27. Lighting is useful here after dark. MALSR is active on 27. ODALS is available on 09. REIL is available on 03 and 21. PAPI is published for all four runway ends and operates continuously. The published pattern altitude is not listed, so use the standard 1,000 ft AGL for light piston traffic unless the current FAA Chart Supplement says otherwise. That puts pattern altitude at about 7,765 ft MSL.

Sweetwater Aviation is on the field. It carries 100LL and Jet A. For clearance delivery, if you cannot reach Flight Service, the published remark says to contact Salt Lake ARTCC. This is a high-elevation airport in southwest Wyoming. Expect density altitude to matter, especially on warm days. Check the current FAA Chart Supplement for any updated remarks before you go.
