02Density altitude and turboprop runway margins

Standard temperature at 1,098 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)	1,098 ft	2,652 ft	2,226 ft	3,339 ft
Warm day (ISA +10)	2,298 ft	2,886 ft	2,352 ft	3,529 ft
Hot day (ISA +20)	3,498 ft	3,120 ft	2,479 ft	3,719 ft
35°C afternoon	3,762 ft	3,172 ft	2,507 ft	3,760 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 9,002 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,760 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 KSUX is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KSUX

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