02Density altitude and turboprop runway margins

Standard temperature at 606 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)	606 ft	2,556 ft	2,174 ft	3,261 ft
Warm day (ISA +10)	1,806 ft	2,790 ft	2,301 ft	3,451 ft
Hot day (ISA +20)	3,006 ft	3,024 ft	2,427 ft	3,641 ft
35°C afternoon	3,151 ft	3,053 ft	2,442 ft	3,664 ft

Planning aid only. Even on a 35°C afternoon the longest runway (08/26, 4,802 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,664 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.
