02Density altitude and turboprop runway margins

Standard temperature at 1,888 ft is about 11°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, 11°C)	1,888 ft	2,806 ft	2,309 ft	3,464 ft
Warm day (ISA +10)	3,088 ft	3,040 ft	2,436 ft	3,654 ft
Hot day (ISA +20)	4,288 ft	3,274 ft	2,562 ft	3,844 ft
35°C afternoon	4,741 ft	3,363 ft	2,610 ft	3,915 ft

Planning aid only. Even on a 35°C afternoon the longest runway (08/26, 5,531 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,915 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 KTNP is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KTNP

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KTNP, 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.
