02Density altitude and turboprop runway margins

Standard temperature at 2,351 ft is about 10°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, 10°C)	2,351 ft	2,897 ft	2,358 ft	3,537 ft
Warm day (ISA +10)	3,551 ft	3,131 ft	2,485 ft	3,727 ft
Hot day (ISA +20)	4,751 ft	3,365 ft	2,611 ft	3,917 ft
35°C afternoon	5,315 ft	3,475 ft	2,671 ft	4,006 ft

Planning aid only. Even on a 35°C afternoon the longest runway (06/24, 7,201 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,006 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 KWJF is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KWJF

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