Madison Municipal Airport serves Madison, South Dakota at 1,718 ft elevation with its longest runway, 15/33, at 5,000 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.

01Runways

Runway	Length × width	Surface	Lighting
15/33	5,000 × 75 ft	asphalt	lit
03/21	2,380 × 200 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,718 ft is about 12°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, 12°C)	1,718 ft	2,773 ft	2,291 ft	3,437 ft
Warm day (ISA +10)	2,918 ft	3,007 ft	2,418 ft	3,627 ft
Hot day (ISA +20)	4,118 ft	3,241 ft	2,544 ft	3,817 ft
35°C afternoon	4,530 ft	3,322 ft	2,588 ft	3,882 ft

Planning aid only. Even on a 35°C afternoon the longest runway (15/33, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,882 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 KMDS is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KMDS

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