Weydahl Field serves Killdeer, North Dakota at 2,256 ft elevation with its longest runway, 12/30, at 4,200 by 50 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 2,256 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)	2,256 ft	2,878 ft	2,348 ft	3,522 ft
Warm day (ISA +10)	3,456 ft	3,112 ft	2,475 ft	3,712 ft
Hot day (ISA +20)	4,656 ft	3,346 ft	2,601 ft	3,902 ft
35°C afternoon	5,197 ft	3,452 ft	2,658 ft	3,987 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 4,200 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,987 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.

Useful as alternates, as fuel stops when the price at K9Y1 is high, or as the longer runway on a hot afternoon.
