Roberts Field serves Redmond, Oregon at 3,080 ft elevation with its longest runway, 05/23, at 7,038 by 150 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.

01Runways

Runway	Length × width	Surface	Lighting

02Density altitude and turboprop runway margins

Standard temperature at 3,080 ft is about 9°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, 9°C)	3,080 ft	3,039 ft	2,435 ft	3,652 ft
Warm day (ISA +10)	4,280 ft	3,273 ft	2,562 ft	3,842 ft
Hot day (ISA +20)	5,480 ft	3,507 ft	2,688 ft	4,032 ft
35°C afternoon	6,219 ft	3,651 ft	2,766 ft	4,149 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 7,038 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,149 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 KRDM is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
S39 Prineville Airport	11 nm E	5,405 ft
KS33 Madras Municipal Airport	25 nm N	5,091 ft
KS21 Sunriver Airport	26 nm SW	5,460 ft
K62S Christmas Valley Airport	65 nm S	5,200 ft

04Jet A prices and FBOs at KRDM

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