K1M4 · Posey Field
Posey Field serves Haleyville, Alabama at 930 ft elevation with its longest runway, 18/36, at 5,008 by 100 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 |
|---|---|---|---|
| 18/36 | 5,008 × 100 ft | asphalt (good) | lit |
02Density altitude and turboprop runway margins
Standard temperature at 930 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) | 930 ft | 2,619 ft | 2,208 ft | 3,312 ft |
| Warm day (ISA +10) | 2,130 ft | 2,853 ft | 2,335 ft | 3,502 ft |
| Hot day (ISA +20) | 3,330 ft | 3,087 ft | 2,461 ft | 3,692 ft |
| 35°C afternoon | 3,553 ft | 3,131 ft | 2,485 ft | 3,727 ft |
