02Density altitude and turboprop runway margins

Standard temperature at 1,044 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)	1,044 ft	2,642 ft	2,220 ft	3,330 ft
Warm day (ISA +10)	2,244 ft	2,876 ft	2,347 ft	3,520 ft
Hot day (ISA +20)	3,444 ft	3,110 ft	2,473 ft	3,710 ft
35°C afternoon	3,695 ft	3,159 ft	2,500 ft	3,750 ft

Planning aid only. Even on a 35°C afternoon the longest runway (14/32, 4,100 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,750 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 KEFW is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KEFW

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