Sparta Fort McCoy Airport serves Sparta, Wisconsin at 837 ft elevation with its longest runway, 11/29, at 4,697 by 100 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 marked joint use. 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.

01Runways

Runway	Length × width	Surface	Lighting

02Density altitude and turboprop runway margins

Standard temperature at 837 ft is about 13°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, 13°C)	837 ft	2,601 ft	2,198 ft	3,297 ft
Warm day (ISA +10)	2,037 ft	2,835 ft	2,325 ft	3,487 ft
Hot day (ISA +20)	3,237 ft	3,069 ft	2,452 ft	3,677 ft
35°C afternoon	3,438 ft	3,109 ft	2,473 ft	3,709 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 4,697 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,709 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.
