02Density altitude and turboprop runway margins
Standard temperature at 620 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) | 620 ft | 2,559 ft | 2,175 ft | 3,263 ft |
| Warm day (ISA +10) | 1,820 ft | 2,793 ft | 2,302 ft | 3,453 ft |
| Hot day (ISA +20) | 3,020 ft | 3,027 ft | 2,429 ft | 3,643 ft |
| 35°C afternoon | 3,169 ft | 3,056 ft | 2,444 ft | 3,666 ft |
