Sioux County Regional Airport serves Maurice, Iowa at 1,409 ft elevation with its longest runway, 17/35, at 5,500 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.

02Density altitude and turboprop runway margins

Standard temperature at 1,409 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)	1,409 ft	2,713 ft	2,259 ft	3,388 ft
Warm day (ISA +10)	2,609 ft	2,947 ft	2,385 ft	3,578 ft
Hot day (ISA +20)	3,809 ft	3,181 ft	2,512 ft	3,768 ft
35°C afternoon	4,147 ft	3,247 ft	2,548 ft	3,821 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 5,500 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,821 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 KSXK is high, or as the longer runway on a hot afternoon.
