02Density altitude and turboprop runway margins
Standard temperature at 235 ft is about 15°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, 15°C) | 235 ft | 2,484 ft | 2,135 ft | 3,202 ft |
| Warm day (ISA +10) | 1,435 ft | 2,718 ft | 2,261 ft | 3,392 ft |
