02Density altitude and turboprop runway margins

Standard temperature at 55 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)	55 ft	2,449 ft	2,116 ft	3,174 ft
Warm day (ISA +10)	1,255 ft	2,683 ft	2,242 ft	3,364 ft
Hot day (ISA +20)	2,455 ft	2,917 ft	2,369 ft	3,554 ft
35°C afternoon	2,468 ft	2,919 ft	2,370 ft	3,556 ft

Planning aid only. Even on a 35°C afternoon the longest runway (10/28, 4,255 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,556 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 KJPX is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KJPX

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