01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 17/35 | 4,000 × 75 ft | concrete | lit |
02Density altitude and turboprop runway margins
Standard temperature at 724 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) | 724 ft | 2,579 ft | 2,186 ft | 3,280 ft |
| Warm day (ISA +10) | 1,924 ft | 2,813 ft | 2,313 ft | 3,469 ft |
| Hot day (ISA +20) | 3,124 ft | 3,047 ft | 2,440 ft | 3,659 ft |
| 35°C afternoon | 3,298 ft | 3,081 ft | 2,458 ft | 3,687 ft |
