02Density altitude and turboprop runway margins

Standard temperature at 1,184 ft is about 13°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, 13°C)	1,184 ft	2,669 ft	2,235 ft	3,352 ft
Warm day (ISA +10)	2,384 ft	2,903 ft	2,362 ft	3,542 ft
Hot day (ISA +20)	3,584 ft	3,137 ft	2,488 ft	3,732 ft
35°C afternoon	3,868 ft	3,192 ft	2,518 ft	3,777 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 5,004 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,777 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.

04Jet A prices and FBOs at KAFJ

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