02Density altitude and turboprop runway margins

Standard temperature at 1,706 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)	1,706 ft	2,771 ft	2,290 ft	3,435 ft
Warm day (ISA +10)	2,906 ft	3,005 ft	2,417 ft	3,625 ft
Hot day (ISA +20)	4,106 ft	3,239 ft	2,543 ft	3,815 ft
35°C afternoon	4,515 ft	3,319 ft	2,586 ft	3,879 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 5,049 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,879 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 KS52 is high, or as the longer runway on a hot afternoon.
