02Density altitude and turboprop runway margins

Standard temperature at 534 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)	534 ft	2,542 ft	2,166 ft	3,250 ft
Warm day (ISA +10)	1,734 ft	2,776 ft	2,293 ft	3,439 ft
Hot day (ISA +20)	2,934 ft	3,010 ft	2,420 ft	3,629 ft
35°C afternoon	3,062 ft	3,035 ft	2,433 ft	3,650 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18/36, 5,001 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,650 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 KENL is high, or as the longer runway on a hot afternoon.
