Jerome County Airport serves Jerome, Idaho at 4,053 ft elevation with its longest runway, 09/27, at 5,002 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 4,053 ft is about 7°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, 7°C)	4,053 ft	3,228 ft	2,538 ft	3,806 ft
Warm day (ISA +10)	5,253 ft	3,463 ft	2,664 ft	3,996 ft
Hot day (ISA +20)	6,453 ft	3,697 ft	2,791 ft	4,186 ft
35°C afternoon	7,426 ft	3,886 ft	2,893 ft	4,340 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 5,002 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,340 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 KJER is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KJER

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KJER, the app flags a price stale after two weeks, and the route finder ranks every field within a corridor of your route by net savings after the cost of the extra cycle. Log a price at KJER or read what a fuel stop actually saves.
