Dillon Airport serves Dillon, Montana at 5,241 ft elevation with its longest runway, 17/35, at 6,501 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.

01Runways

04/22	3,600 × 60 ft	asphalt (fair)	lit

02Density altitude and turboprop runway margins

Standard temperature at 5,241 ft is about 5°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, 5°C)	5,241 ft	3,460 ft	2,663 ft	3,994 ft
Warm day (ISA +10)	6,441 ft	3,694 ft	2,790 ft	4,184 ft
Hot day (ISA +20)	7,641 ft	3,928 ft	2,916 ft	4,374 ft
35°C afternoon	8,899 ft	4,174 ft	3,049 ft	4,573 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 6,501 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,573 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 KDLN is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KDLN

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