De Quincy Industrial Airpark serves De Quincy, Louisiana at 81 ft elevation with its longest runway, 15/33, at 5,000 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 |
|---|---|---|---|
| 15/33 | 5,000 × 75 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 81 ft is about 15°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, 15°C) | 81 ft | 2,454 ft | 2,119 ft | 3,178 ft |
| Warm day (ISA +10) | 1,281 ft | 2,688 ft | 2,245 ft | 3,368 ft |
| Hot day (ISA +20) | 2,481 ft | 2,922 ft | 2,372 ft | 3,558 ft |
| 35°C afternoon | 2,500 ft | 2,926 ft | 2,374 ft | 3,561 ft |
