Plains Airport serves Plains, Montana at 2,467 ft elevation with its longest runway, 13/31, at 4,650 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 2,467 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)	2,467 ft	2,919 ft	2,370 ft	3,555 ft
Warm day (ISA +10)	3,667 ft	3,153 ft	2,497 ft	3,745 ft
Hot day (ISA +20)	4,867 ft	3,387 ft	2,623 ft	3,935 ft
35°C afternoon	5,459 ft	3,503 ft	2,686 ft	4,029 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 4,650 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,029 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 KS34 is high, or as the longer runway on a hot afternoon.
