Potomac Airpark serves Berkeley Springs, West Virginia at 412 ft elevation with its longest runway, 11/29, at 4,979 by 70 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 412 ft is about 14°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, 14°C)	412 ft	2,518 ft	2,153 ft	3,230 ft
Warm day (ISA +10)	1,612 ft	2,752 ft	2,280 ft	3,420 ft
Hot day (ISA +20)	2,812 ft	2,986 ft	2,407 ft	3,610 ft
35°C afternoon	2,911 ft	3,006 ft	2,417 ft	3,626 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 4,979 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,626 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 KW35 is high, or as the longer runway on a hot afternoon.
