Napa County Airport serves Napa, California at 35 ft elevation with its longest runway, 01L/19R, at 5,930 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.

Runway	Length × width	Surface	Lighting
01L/19R	5,930 × 150 ft	asphalt	lit

01R/19L	2,510 × 75 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 35 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)	35 ft	2,445 ft	2,114 ft	3,171 ft
Warm day (ISA +10)	1,235 ft	2,679 ft	2,240 ft	3,360 ft
Hot day (ISA +20)	2,435 ft	2,913 ft	2,367 ft	3,550 ft
35°C afternoon	2,443 ft	2,914 ft	2,368 ft	3,552 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01L/19R, 5,930 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,552 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 KAPC is high, or as the longer runway on a hot afternoon.

KDWA Yolo County Davis Woodland Winters Airport	30 nm NE	6,000 ft
KOAK Oakland San Francisco Bay Airport	30 nm S	10,520 ft

04Jet A prices and FBOs at KAPC

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