01Runways
| Runway | Length × width | Surface | Lighting |

| 18L/36R | 10,001 × 150 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 629 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) | 629 ft | 2,561 ft | 2,176 ft | 3,265 ft |
| Warm day (ISA +10) | 1,829 ft | 2,795 ft | 2,303 ft | 3,454 ft |
| Hot day (ISA +20) | 3,029 ft | 3,029 ft | 2,430 ft | 3,644 ft |
| 35°C afternoon | 3,180 ft | 3,058 ft | 2,445 ft | 3,668 ft |
