02Density altitude and turboprop runway margins

Standard temperature at 1,292 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)	1,292 ft	2,690 ft	2,246 ft	3,369 ft
Warm day (ISA +10)	2,492 ft	2,924 ft	2,373 ft	3,559 ft
Hot day (ISA +20)	3,692 ft	3,158 ft	2,500 ft	3,749 ft
35°C afternoon	4,002 ft	3,219 ft	2,532 ft	3,798 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 4,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,798 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 KY51 is high, or as the longer runway on a hot afternoon.
