South Alabama Regional At Bill Benton Field Airport serves Andalusia/Opp, Alabama at 310 ft elevation with its longest runway, 11/29, at 6,000 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 310 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)	310 ft	2,498 ft	2,143 ft	3,214 ft
Warm day (ISA +10)	1,510 ft	2,733 ft	2,269 ft	3,404 ft
Hot day (ISA +20)	2,710 ft	2,967 ft	2,396 ft	3,594 ft
35°C afternoon	2,784 ft	2,981 ft	2,404 ft	3,606 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 6,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,606 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 K79J is high, or as the longer runway on a hot afternoon.
