02Density altitude and turboprop runway margins

Standard temperature at 955 ft is about 13°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, 13°C)	955 ft	2,624 ft	2,211 ft	3,316 ft
Warm day (ISA +10)	2,155 ft	2,858 ft	2,337 ft	3,506 ft
Hot day (ISA +20)	3,355 ft	3,092 ft	2,464 ft	3,696 ft
35°C afternoon	3,584 ft	3,137 ft	2,488 ft	3,732 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 8,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,732 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 KGYH is high, or as the longer runway on a hot afternoon.
