01Runways

Runway	Length × width	Surface	Lighting
11/29	4,501 × 75 ft	asphalt	lit
17/35	1,900 × 60 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 2,571 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)	2,571 ft	2,939 ft	2,381 ft	3,572 ft
Warm day (ISA +10)	3,771 ft	3,173 ft	2,508 ft	3,762 ft
Hot day (ISA +20)	4,971 ft	3,408 ft	2,634 ft	3,952 ft
35°C afternoon	5,588 ft	3,528 ft	2,700 ft	4,049 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 4,501 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,049 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 KLEM is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KLEM

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