01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 02/20 | 5,000 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 3,323 ft is about 8°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, 8°C) | 3,323 ft | 3,086 ft | 2,461 ft | 3,691 ft |
| Warm day (ISA +10) | 4,523 ft | 3,320 ft | 2,587 ft | 3,881 ft |
| Hot day (ISA +20) | 5,723 ft | 3,554 ft | 2,714 ft | 4,071 ft |
| 35°C afternoon | 6,521 ft | 3,710 ft | 2,798 ft | 4,197 ft |
