02Density altitude and turboprop runway margins

Standard temperature at 1,197 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)	1,197 ft	2,671 ft	2,236 ft	3,354 ft
Warm day (ISA +10)	2,397 ft	2,906 ft	2,363 ft	3,544 ft
Hot day (ISA +20)	3,597 ft	3,140 ft	2,489 ft	3,734 ft
35°C afternoon	3,884 ft	3,196 ft	2,520 ft	3,780 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18/36, 5,056 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,780 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.
