02Density altitude and turboprop runway margins

Standard temperature at 2,085 ft is about 11°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, 11°C)	2,085 ft	2,845 ft	2,330 ft	3,495 ft
Warm day (ISA +10)	3,285 ft	3,079 ft	2,457 ft	3,685 ft
Hot day (ISA +20)	4,485 ft	3,313 ft	2,583 ft	3,875 ft
35°C afternoon	4,985 ft	3,410 ft	2,636 ft	3,954 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 4,500 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,954 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.
