Brookings Regional Airport serves Brookings, South Dakota at 1,648 ft elevation with its longest runway, 12/30, at 6,000 by 100 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 1,648 ft is about 12°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, 12°C)	1,648 ft	2,759 ft	2,284 ft	3,426 ft
Warm day (ISA +10)	2,848 ft	2,993 ft	2,410 ft	3,616 ft
Hot day (ISA +20)	4,048 ft	3,228 ft	2,537 ft	3,806 ft
35°C afternoon	4,444 ft	3,305 ft	2,579 ft	3,868 ft

Planning aid only. Even on a 35°C afternoon the longest runway (12/30, 6,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,868 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 KBKX is high, or as the longer runway on a hot afternoon.
