01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 10/28 | 5,001 × 100 ft | asphalt | lit |
| 01/19 | 2,501 × 50 ft | asphalt (good) | unlit |
02Density altitude and turboprop runway margins
Standard temperature at 684 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) | 684 ft | 2,571 ft | 2,182 ft | 3,273 ft |
| Warm day (ISA +10) | 1,884 ft | 2,805 ft | 2,309 ft | 3,463 ft |
| Hot day (ISA +20) | 3,084 ft | 3,040 ft | 2,435 ft | 3,653 ft |
| 35°C afternoon | 3,248 ft | 3,071 ft | 2,453 ft | 3,679 ft |

04Jet A prices and FBOs at KISQ
No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KISQ, 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. Log a price at KISQ or read what a fuel stop actually saves.
