01Runways

Runway	Length × width	Surface	Lighting
09/27	4,299 × 75 ft	asphalt	lit
14/32	3,278 × 120 ft	turf	unlit
05/23	2,054 × 120 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 669 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)	669 ft	2,568 ft	2,181 ft	3,271 ft
Warm day (ISA +10)	1,869 ft	2,803 ft	2,307 ft	3,461 ft
Hot day (ISA +20)	3,069 ft	3,037 ft	2,434 ft	3,651 ft
35°C afternoon	3,230 ft	3,068 ft	2,451 ft	3,676 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 4,299 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,676 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 KSJX is high, or as the longer runway on a hot afternoon.
