01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 10/28 | 4,149 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 686 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) | 686 ft | 2,572 ft | 2,182 ft | 3,274 ft |
| Warm day (ISA +10) | 1,886 ft | 2,806 ft | 2,309 ft | 3,463 ft |
| Hot day (ISA +20) | 3,086 ft | 3,040 ft | 2,436 ft | 3,653 ft |
| 35°C afternoon | 3,251 ft | 3,072 ft | 2,453 ft | 3,679 ft |
