Stennis International Airport serves Bay St Louis, Mississippi at 23 ft elevation with its longest runway, 18/36, at 8,498 by 150 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.

02Density altitude and turboprop runway margins

Standard temperature at 23 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)	23 ft	2,442 ft	2,112 ft	3,169 ft
Warm day (ISA +10)	1,223 ft	2,677 ft	2,239 ft	3,359 ft
Hot day (ISA +20)	2,423 ft	2,911 ft	2,366 ft	3,548 ft
35°C afternoon	2,429 ft	2,912 ft	2,366 ft	3,549 ft

Planning aid only. Even on a 35°C afternoon the longest runway (18/36, 8,498 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,549 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.

03Nearby fields with 5,000 ft or more

Useful as alternates, as fuel stops when the price at KHSA is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KHSA

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