Lewistown Municipal Airport serves Lewistown, Montana at 4,170 ft elevation with its longest runway, 08/26, at 6,100 by 100 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

01Runways

Runway	Length × width	Surface	Lighting
08/26	6,100 × 100 ft	asphalt	lit
03/21	5,600 × 101 ft	asphalt	lit
13/31	4,102 × 62 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 4,170 ft is about 7°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, 7°C)	4,170 ft	3,251 ft	2,550 ft	3,825 ft
Warm day (ISA +10)	5,370 ft	3,485 ft	2,677 ft	4,015 ft
Hot day (ISA +20)	6,570 ft	3,719 ft	2,803 ft	4,205 ft
35°C afternoon	7,571 ft	3,915 ft	2,909 ft	4,363 ft

Planning aid only. Even on a 35°C afternoon the longest runway (08/26, 6,100 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,363 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 KLWT is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KLWT

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