02Density altitude and turboprop runway margins

Standard temperature at 981 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)	981 ft	2,629 ft	2,213 ft	3,320 ft
Warm day (ISA +10)	2,181 ft	2,863 ft	2,340 ft	3,510 ft
Hot day (ISA +20)	3,381 ft	3,097 ft	2,467 ft	3,700 ft
35°C afternoon	3,616 ft	3,143 ft	2,491 ft	3,737 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18/36, 4,423 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,737 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.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KC59 is high, or as the longer runway on a hot afternoon.
