02Density altitude and turboprop runway margins

Standard temperature at 712 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)	712 ft	2,577 ft	2,185 ft	3,278 ft
Warm day (ISA +10)	1,912 ft	2,811 ft	2,312 ft	3,468 ft
Hot day (ISA +20)	3,112 ft	3,045 ft	2,438 ft	3,657 ft
35°C afternoon	3,283 ft	3,078 ft	2,456 ft	3,685 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 6,501 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,685 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 KARR is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KARR

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