Arco Butte County Airport serves Arco, Idaho at 5,332 ft elevation with its longest runway, 6/24, at 4,801 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 5,332 ft is about 4°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, 4°C)	5,332 ft	3,478 ft	2,673 ft	4,009 ft
Warm day (ISA +10)	6,532 ft	3,712 ft	2,799 ft	4,199 ft
Hot day (ISA +20)	7,732 ft	3,946 ft	2,926 ft	4,389 ft
35°C afternoon	9,012 ft	4,196 ft	3,061 ft	4,591 ft

Planning aid only. Even on a 35°C afternoon the longest runway (6/24, 4,801 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,591 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 KAOC is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KAOC

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