Prineville Airport serves Prineville, Oregon at 3,250 ft elevation with its longest runway, 11/29, at 5,405 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 3,250 ft is about 8°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, 8°C)	3,250 ft	3,072 ft	2,453 ft	3,679 ft
Warm day (ISA +10)	4,450 ft	3,306 ft	2,579 ft	3,869 ft
Hot day (ISA +20)	5,650 ft	3,540 ft	2,706 ft	4,059 ft
35°C afternoon	6,430 ft	3,692 ft	2,788 ft	4,183 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 5,405 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,183 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 S39 is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
KRDM Roberts Field	11 nm W	7,038 ft
KS33 Madras Municipal Airport	25 nm NW	5,091 ft
KS21 Sunriver Airport	34 nm SW	5,460 ft

04Jet A prices and FBOs at S39

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at S39, 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 S39 or read what a fuel stop actually saves.
