K05C · Griffith-Merrillville Airport
Griffith-Merrillville Airport serves Griffith, Indiana at 634 ft elevation with its longest runway, 08/26, at 4,900 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 |
|---|---|---|---|
| 08/26 | 4,900 × 75 ft | asphalt (good) | lit |
02Density altitude and turboprop runway margins
Standard temperature at 634 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) | 634 ft | 2,562 ft | 2,177 ft | 3,265 ft |
| Warm day (ISA +10) | 1,834 ft | 2,796 ft | 2,303 ft | 3,455 ft |
| Hot day (ISA +20) | 3,034 ft | 3,030 ft | 2,430 ft | 3,645 ft |
| 35°C afternoon | 3,186 ft | 3,059 ft | 2,446 ft | 3,669 ft |

04Jet A prices and FBOs at K05C
No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K05C, 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 K05C or read what a fuel stop actually saves.
