02Density altitude and turboprop runway margins

Standard temperature at 3,315 ft is about 8°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, 8°C)	3,315 ft	3,085 ft	2,460 ft	3,690 ft
Warm day (ISA +10)	4,515 ft	3,319 ft	2,586 ft	3,879 ft
Hot day (ISA +20)	5,715 ft	3,553 ft	2,713 ft	4,069 ft
35°C afternoon	6,511 ft	3,708 ft	2,797 ft	4,195 ft

Planning aid only. Even on a 35°C afternoon the longest runway (08/26, 5,381 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,195 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 KGNC is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KGNC

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