KCZT · Dimmit County Airport
Dimmit County Airport serves Carrizo Springs, Texas at 599 ft elevation with its longest runway, 13/31, at 5,003 by 75 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 13/31 | 5,003 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 599 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) | 599 ft | 2,555 ft | 2,173 ft | 3,260 ft |
| Warm day (ISA +10) | 1,799 ft | 2,789 ft | 2,300 ft | 3,450 ft |
| Hot day (ISA +20) | 2,999 ft | 3,023 ft | 2,426 ft | 3,640 ft |
| 35°C afternoon | 3,143 ft | 3,051 ft | 2,442 ft | 3,662 ft |

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