Butts AAF (Fort Carson) Air Field serves Fort Carson, Colorado at 5,838 ft elevation with its longest runway, 13/31, at 4,500 by 75 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.

Military airfield. This is a military airfield in the FAA file. It is listed here for reference and for emergency planning. Civil use needs prior permission, there is no FBO, and no Jet A you can buy. Do not plan it as a fuel stop or a routine alternate.

02Density altitude and turboprop runway margins

Standard temperature at 5,838 ft is about 3°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, 3°C)	5,838 ft	3,577 ft	2,726 ft	4,089 ft
Warm day (ISA +10)	7,038 ft	3,811 ft	2,853 ft	4,279 ft
Hot day (ISA +20)	8,238 ft	4,045 ft	2,979 ft	4,469 ft
35°C afternoon	9,639 ft	4,318 ft	3,127 ft	4,690 ft

Planning aid only. On a 35°C afternoon the longest runway (13/31, 4,500 ft) is within 20 percent of the 1.5x landing figure for a Meridian-class turboprop (4,690 ft). Plan hot-day departures for the morning and check the POH. 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.

04Fuel and services at KFCS

There is no public FBO fuel to log at KFCS. JetDesk collects Jet A prices that pilots actually paid, at civil fields, and its route finder leaves military and private-use fields out of every ranking. Read what a fuel stop actually saves.
