01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 02/20 | 4,800 × 75 ft | asphalt (fair) | lit |
02Density altitude and turboprop runway margins
Standard temperature at 570 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) | 570 ft | 2,549 ft | 2,170 ft | 3,255 ft |
| Warm day (ISA +10) | 1,770 ft | 2,783 ft | 2,297 ft | 3,445 ft |
| Hot day (ISA +20) | 2,970 ft | 3,017 ft | 2,423 ft | 3,635 ft |
| 35°C afternoon | 3,107 ft | 3,044 ft | 2,438 ft | 3,657 ft |
