02Density altitude and turboprop runway margins

Standard temperature at 540 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)	540 ft	2,543 ft	2,167 ft	3,250 ft
Warm day (ISA +10)	1,740 ft	2,777 ft	2,294 ft	3,440 ft
Hot day (ISA +20)	2,940 ft	3,011 ft	2,420 ft	3,630 ft
35°C afternoon	3,070 ft	3,037 ft	2,434 ft	3,651 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18/36, 4,359 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,651 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 KSIV is high, or as the longer runway on a hot afternoon.
