01Runways

Runway	Length × width	Surface	Lighting
05/23	4,800 × 75 ft	asphalt	lit
14/32	3,260 × 190 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 666 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)	666 ft	2,568 ft	2,180 ft	3,270 ft
Warm day (ISA +10)	1,866 ft	2,802 ft	2,307 ft	3,460 ft
Hot day (ISA +20)	3,066 ft	3,036 ft	2,433 ft	3,650 ft
35°C afternoon	3,226 ft	3,067 ft	2,450 ft	3,676 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 4,800 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,676 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 KLWA is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KLWA

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