01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 18/36 | 4,001 × 75 ft | concrete | lit |
02Density altitude and turboprop runway margins
Standard temperature at 771 ft is about 13°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, 13°C) | 771 ft | 2,588 ft | 2,191 ft | 3,287 ft |
| Warm day (ISA +10) | 1,971 ft | 2,822 ft | 2,318 ft | 3,477 ft |
| Hot day (ISA +20) | 3,171 ft | 3,056 ft | 2,445 ft | 3,667 ft |
| 35°C afternoon | 3,356 ft | 3,093 ft | 2,464 ft | 3,696 ft |
