01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 14/32 | 5,322 × 75 ft | asphalt | lit |
| 03/21 | 3,400 × 60 ft | asphalt | unlit |
02Density altitude and turboprop runway margins
Standard temperature at 5,737 ft is about 4°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, 4°C) | 5,737 ft | 3,557 ft | 2,715 ft | 4,073 ft |
| Warm day (ISA +10) | 6,937 ft | 3,791 ft | 2,842 ft | 4,263 ft |
| Hot day (ISA +20) | 8,137 ft | 4,025 ft | 2,968 ft | 4,453 ft |
| 35°C afternoon | 9,514 ft | 4,294 ft | 3,114 ft | 4,671 ft |
