| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 04/22 | 5,505 × 100 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 706 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) | 706 ft | 2,576 ft | 2,184 ft | 3,277 ft |
| Warm day (ISA +10) | 1,906 ft | 2,810 ft | 2,311 ft | 3,467 ft |
| Hot day (ISA +20) | 3,106 ft | 3,044 ft | 2,438 ft | 3,657 ft |
| 35°C afternoon | 3,275 ft | 3,077 ft | 2,456 ft | 3,683 ft |
