Stinson Municipal Airport serves San Antonio, Texas at 577 ft elevation with its longest runway, 09/27, 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.

02Density altitude and turboprop runway margins

Standard temperature at 577 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)	577 ft	2,551 ft	2,171 ft	3,256 ft
Warm day (ISA +10)	1,777 ft	2,785 ft	2,297 ft	3,446 ft
Hot day (ISA +20)	2,977 ft	3,019 ft	2,424 ft	3,636 ft
35°C afternoon	3,115 ft	3,046 ft	2,439 ft	3,658 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,658 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 KSSF is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
KSAT San Antonio International Airport	12 nm N	8,505 ft
KCVB Castroville Municipal Airport	20 nm W	5,001 ft
K5C1 Boerne Stage Field	26 nm NW	5,006 ft

04Jet A prices and FBOs at KSSF

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