01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 01/19 | 9,001 × 150 ft | concrete | lit |
| 07/25 | 5,028 × 100 ft | concrete | lit |
02Density altitude and turboprop runway margins
Standard temperature at 690 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) | 690 ft | 2,573 ft | 2,183 ft | 3,274 ft |
| Warm day (ISA +10) | 1,890 ft | 2,807 ft | 2,309 ft | 3,464 ft |
| Hot day (ISA +20) | 3,090 ft | 3,041 ft | 2,436 ft | 3,654 ft |
| 35°C afternoon | 3,256 ft | 3,073 ft | 2,454 ft | 3,680 ft |

04Jet A prices and FBOs at KAPN
No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KAPN, the app flags a price stale after two weeks, and the route finder ranks every field within a corridor of your route by net savings after the cost of the extra cycle.
