01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 09/27 | 4,001 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 657 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) | 657 ft | 2,566 ft | 2,179 ft | 3,269 ft |
| Warm day (ISA +10) | 1,857 ft | 2,800 ft | 2,306 ft | 3,459 ft |
| Hot day (ISA +20) | 3,057 ft | 3,034 ft | 2,433 ft | 3,649 ft |
| 35°C afternoon | 3,215 ft | 3,065 ft | 2,449 ft | 3,674 ft |
