Houston Southwest Airport serves Rosharon, Texas at 68 ft elevation with its longest runway, 09/27, at 5,002 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 68 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)	68 ft	2,451 ft	2,117 ft	3,176 ft
Warm day (ISA +10)	1,268 ft	2,685 ft	2,244 ft	3,366 ft
Hot day (ISA +20)	2,468 ft	2,919 ft	2,370 ft	3,556 ft
35°C afternoon	2,484 ft	2,922 ft	2,372 ft	3,558 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 5,002 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,558 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 KAXH is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KAXH

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