Witham Field serves Stuart, Florida at 16 ft elevation with its longest runway, 12/30, at 5,828 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.

01Runways

Runway	Length × width	Surface	Lighting
12/30	5,828 × 100 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 16 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)	16 ft	2,441 ft	2,112 ft	3,168 ft
Warm day (ISA +10)	1,216 ft	2,675 ft	2,238 ft	3,357 ft
Hot day (ISA +20)	2,416 ft	2,909 ft	2,365 ft	3,547 ft
35°C afternoon	2,420 ft	2,910 ft	2,365 ft	3,548 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 5,828 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,548 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 KSUA is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSUA

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