02Density altitude and turboprop runway margins

Standard temperature at 1,076 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)	1,076 ft	2,648 ft	2,224 ft	3,335 ft
Warm day (ISA +10)	2,276 ft	2,882 ft	2,350 ft	3,525 ft
Hot day (ISA +20)	3,476 ft	3,116 ft	2,477 ft	3,715 ft
35°C afternoon	3,734 ft	3,166 ft	2,504 ft	3,756 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 4,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,756 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 KOLZ is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KOLZ

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