Deer Lodge City County Airport serves Deer Lodge, Montana at 4,693 ft elevation with its longest runway, 13/31, at 5,800 by 75 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.

02Density altitude and turboprop runway margins

Standard temperature at 4,693 ft is about 6°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, 6°C)	4,693 ft	3,353 ft	2,605 ft	3,908 ft
Warm day (ISA +10)	5,893 ft	3,587 ft	2,732 ft	4,098 ft
Hot day (ISA +20)	7,093 ft	3,821 ft	2,858 ft	4,287 ft
35°C afternoon	8,219 ft	4,041 ft	2,977 ft	4,466 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 5,800 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,466 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 K38S is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K38S

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K38S, 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 K38S or read what a fuel stop actually saves.
