01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 18/36 | 4,001 × 60 ft | asphalt (good) | lit |
02Density altitude and turboprop runway margins
Standard temperature at 786 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) | 786 ft | 2,591 ft | 2,193 ft | 3,289 ft |
| Warm day (ISA +10) | 1,986 ft | 2,825 ft | 2,320 ft | 3,479 ft |
| Hot day (ISA +20) | 3,186 ft | 3,059 ft | 2,446 ft | 3,669 ft |
| 35°C afternoon | 3,375 ft | 3,096 ft | 2,466 ft | 3,699 ft |
