02Density altitude and turboprop runway margins

Standard temperature at 882 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)	882 ft	2,610 ft	2,203 ft	3,305 ft
Warm day (ISA +10)	2,082 ft	2,844 ft	2,330 ft	3,494 ft
Hot day (ISA +20)	3,282 ft	3,078 ft	2,456 ft	3,684 ft
35°C afternoon	3,494 ft	3,119 ft	2,479 ft	3,718 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,718 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.
