KSAT · San Antonio International Airport
San Antonio International Airport serves San Antonio, Texas at 809 ft elevation with its longest runway, 04/22, at 8,505 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.

01Runways
| Runway | Length × width | Surface | Lighting |
|---|---|---|---|
| 04/22 | 8,505 × 150 ft | concrete | lit |
| 13R/31L | 8,502 × 150 ft | concrete | lit |
| 13L/31R | 5,519 × 100 ft | asphalt | lit |
02Density altitude and turboprop runway margins
Standard temperature at 809 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) | 809 ft | 2,596 ft | 2,195 ft | 3,293 ft |
| Warm day (ISA +10) | 2,009 ft | 2,830 ft | 2,322 ft | 3,483 ft |
| Hot day (ISA +20) | 3,209 ft | 3,064 ft | 2,449 ft | 3,673 ft |
| 35°C afternoon | 3,403 ft | 3,102 ft | 2,469 ft | 3,704 ft |
03Nearby fields with 5,000 ft or more
Useful as alternates, as fuel stops when the price at KSAT is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSAT
No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KSAT, 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 KSAT or read what a fuel stop actually saves.
