02Density altitude and turboprop runway margins

Standard temperature at 570 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)	570 ft	2,549 ft	2,170 ft	3,255 ft
Warm day (ISA +10)	1,770 ft	2,783 ft	2,297 ft	3,445 ft
Hot day (ISA +20)	2,970 ft	3,017 ft	2,423 ft	3,635 ft
35°C afternoon	3,107 ft	3,044 ft	2,438 ft	3,657 ft

Planning aid only. Even on a 35°C afternoon the longest runway (15/33, 4,108 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,657 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.
