02Density altitude and turboprop runway margins

Standard temperature at 420 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)	420 ft	2,520 ft	2,154 ft	3,231 ft
Warm day (ISA +10)	1,620 ft	2,754 ft	2,281 ft	3,421 ft
Hot day (ISA +20)	2,820 ft	2,988 ft	2,408 ft	3,611 ft
35°C afternoon	2,921 ft	3,008 ft	2,418 ft	3,627 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01/19, 4,011 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,627 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 KW78 is high, or as the longer runway on a hot afternoon.
