Southern Seaplane Airport serves Belle Chasse, Louisiana at 0 ft elevation with its longest runway, 02W/20W, at 5,000 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.

Private-use airfield. The FAA file marks this field private use. It is listed here for reference. Landing needs the owner's prior permission, and there may be no fuel or services. Do not plan it as a fuel stop or a routine alternate.

01Runways

02/20	3,200 × 40 ft	asphalt (fair)	lit

02Density altitude and turboprop runway margins

Standard temperature at 0 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)	0 ft	2,438 ft	2,110 ft	3,165 ft
Warm day (ISA +10)	1,200 ft	2,672 ft	2,237 ft	3,355 ft
Hot day (ISA +20)	2,400 ft	2,906 ft	2,363 ft	3,545 ft
35°C afternoon	2,400 ft	2,906 ft	2,363 ft	3,545 ft

Planning aid only. Even on a 35°C afternoon the longest runway (02W/20W, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,545 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.
