02Density altitude and turboprop runway margins

Standard temperature at 2,693 ft is about 10°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, 10°C)	2,693 ft	2,963 ft	2,394 ft	3,591 ft
Warm day (ISA +10)	3,893 ft	3,197 ft	2,521 ft	3,781 ft
Hot day (ISA +20)	5,093 ft	3,431 ft	2,647 ft	3,971 ft
35°C afternoon	5,739 ft	3,557 ft	2,715 ft	4,073 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01/19, 4,151 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,073 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 KHLX is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KHLX

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