02Density altitude and turboprop runway margins

Standard temperature at 2,857 ft is about 9°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, 9°C)	2,857 ft	2,995 ft	2,411 ft	3,617 ft
Warm day (ISA +10)	4,057 ft	3,229 ft	2,538 ft	3,807 ft
Hot day (ISA +20)	5,257 ft	3,463 ft	2,665 ft	3,997 ft
35°C afternoon	5,943 ft	3,597 ft	2,737 ft	4,105 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 4,743 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,105 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 KBLF is high, or as the longer runway on a hot afternoon.
