01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 09/27 | 7,000 × 100 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 7,135 ft is about 1°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, 1°C) | 7,135 ft | 3,830 ft | 2,863 ft | 4,294 ft |
| Warm day (ISA +10) | 8,335 ft | 4,064 ft | 2,989 ft | 4,484 ft |
| Hot day (ISA +20) | 9,535 ft | 4,298 ft | 3,116 ft | 4,674 ft |
| 35°C afternoon | 11,247 ft | 4,632 ft | 3,297 ft | 4,945 ft |
