Ozark-Blackwell Field serves Ozark, Alabama at 356 ft elevation with its longest runway, 12/30, at 4,200 by 80 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 356 ft is about 14°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, 14°C)	356 ft	2,507 ft	2,148 ft	3,221 ft
Warm day (ISA +10)	1,556 ft	2,741 ft	2,274 ft	3,411 ft
Hot day (ISA +20)	2,756 ft	2,976 ft	2,401 ft	3,601 ft
35°C afternoon	2,841 ft	2,992 ft	2,410 ft	3,615 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 4,200 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,615 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 K71U is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K71U

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K71U, 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 K71U or read what a fuel stop actually saves.
