| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 03/21 | 5,001 × 100 ft | asphalt (good) | lit |
02Density altitude and turboprop runway margins
Standard temperature at 719 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) | 719 ft | 2,578 ft | 2,186 ft | 3,279 ft |
| Warm day (ISA +10) | 1,919 ft | 2,812 ft | 2,312 ft | 3,469 ft |
| Hot day (ISA +20) | 3,119 ft | 3,046 ft | 2,439 ft | 3,659 ft |
| 35°C afternoon | 3,292 ft | 3,080 ft | 2,457 ft | 3,686 ft |
