02Density altitude and turboprop runway margins

Standard temperature at 3,204 ft is about 9°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, 9°C)	3,204 ft	3,063 ft	2,448 ft	3,672 ft
Warm day (ISA +10)	4,404 ft	3,297 ft	2,575 ft	3,862 ft
Hot day (ISA +20)	5,604 ft	3,531 ft	2,701 ft	4,052 ft
35°C afternoon	6,373 ft	3,681 ft	2,782 ft	4,174 ft

Planning aid only. Even on a 35°C afternoon the longest runway (14/32, 8,701 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,174 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 KRAP is high, or as the longer runway on a hot afternoon.

KCUT Custer County Airport	31 nm SW	5,500 ft

04Jet A prices and FBOs at KRAP

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