01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 18/36 | 5,503 × 100 ft | asphalt | lit |
| 08/26 | 2,505 × 140 ft | graded earth | unlit |
02Density altitude and turboprop runway margins
Standard temperature at 799 ft is about 13°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, 13°C) | 799 ft | 2,594 ft | 2,194 ft | 3,291 ft |
| Warm day (ISA +10) | 1,999 ft | 2,828 ft | 2,321 ft | 3,481 ft |
| Hot day (ISA +20) | 3,199 ft | 3,062 ft | 2,447 ft | 3,671 ft |
| 35°C afternoon | 3,391 ft | 3,099 ft | 2,468 ft | 3,702 ft |
