| Runway | Length × width | Surface | Lighting |

02Density altitude and turboprop runway margins
Standard temperature at 711 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) | 711 ft | 2,577 ft | 2,185 ft | 3,278 ft |
| Warm day (ISA +10) | 1,911 ft | 2,811 ft | 2,312 ft | 3,467 ft |
| Hot day (ISA +20) | 3,111 ft | 3,045 ft | 2,438 ft | 3,657 ft |
| 35°C afternoon | 3,282 ft | 3,078 ft | 2,456 ft | 3,684 ft |
