Central Wyoming Regional Airport serves Riverton, Wyoming at 5,525 ft elevation with its longest runway, 10/28, at 8,204 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

02Density altitude and turboprop runway margins

Standard temperature at 5,525 ft is about 4°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, 4°C)	5,525 ft	3,516 ft	2,693 ft	4,039 ft
Warm day (ISA +10)	6,725 ft	3,750 ft	2,819 ft	4,229 ft
Hot day (ISA +20)	7,925 ft	3,984 ft	2,946 ft	4,419 ft
35°C afternoon	9,251 ft	4,242 ft	3,086 ft	4,629 ft

Planning aid only. Even on a 35°C afternoon the longest runway (10/28, 8,204 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,629 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 KRIW is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KRIW

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KRIW, 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 KRIW or read what a fuel stop actually saves.
