Southwest Wyoming Regional Airport serves Rock Springs, Wyoming at 6,764 ft elevation with its longest runway, 09/27, at 10,002 by 150 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

01Runways

Runway	Length × width	Surface	Lighting
09/27	10,002 × 150 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 6,764 ft is about 1°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.

Conditions	Density altitude	Takeoff est.	Landing est.	Landing × 1.5
Standard day (ISA, 1°C)	6,764 ft	3,757 ft	2,824 ft	4,235 ft
Warm day (ISA +10)	7,964 ft	3,991 ft	2,950 ft	4,425 ft
Hot day (ISA +20)	9,164 ft	4,225 ft	3,077 ft	4,615 ft
35°C afternoon	10,787 ft	4,542 ft	3,248 ft	4,872 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 10,002 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,872 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KRKS is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KRKS

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KRKS, the app flags a price stale after two weeks, and the route finder ranks every field within a corridor of your route by net savings after the cost of the extra cycle. Log a price at KRKS or read what a fuel stop actually saves.
