Libby Airport serves Libby, Montana at 2,601 ft elevation with its longest runway, 15/33, at 5,003 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 2,601 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)	2,601 ft	2,945 ft	2,384 ft	3,577 ft
Warm day (ISA +10)	3,801 ft	3,179 ft	2,511 ft	3,767 ft
Hot day (ISA +20)	5,001 ft	3,413 ft	2,638 ft	3,956 ft
35°C afternoon	5,625 ft	3,535 ft	2,703 ft	4,055 ft

Planning aid only. Even on a 35°C afternoon the longest runway (15/33, 5,003 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,055 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 KS59 is high, or as the longer runway on a hot afternoon.
