Sturgis Municipal Airport serves Sturgis, South Dakota at 3,243 ft elevation with its longest runway, 11/29, at 5,100 by 75 ft.

02Density altitude and turboprop runway margins

Standard temperature at 3,243 ft is about 9°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, 9°C)	3,243 ft	3,071 ft	2,452 ft	3,678 ft
Warm day (ISA +10)	4,443 ft	3,305 ft	2,579 ft	3,868 ft
Hot day (ISA +20)	5,643 ft	3,539 ft	2,705 ft	4,058 ft
35°C afternoon	6,421 ft	3,690 ft	2,787 ft	4,181 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 5,100 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,181 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 K49B is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K49B

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K49B, 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 K49B or read what a fuel stop actually saves.
