02Density altitude and turboprop runway margins

Standard temperature at 1,306 ft is about 12°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, 12°C)	1,306 ft	2,693 ft	2,248 ft	3,372 ft
Warm day (ISA +10)	2,506 ft	2,927 ft	2,374 ft	3,562 ft
Hot day (ISA +20)	3,706 ft	3,161 ft	2,501 ft	3,751 ft
35°C afternoon	4,019 ft	3,222 ft	2,534 ft	3,801 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 6,094 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,801 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 KYKN is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KYKN

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