Bear Lake County Airport serves Paris, Idaho at 5,928 ft elevation with its longest runway, 10/28, at 5,728 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.

01Runways

Runway	Length × width	Surface	Lighting
10/28	5,728 × 75 ft	asphalt (good)	lit
16/34	4,590 × 60 ft	asphalt (good)	unlit

02Density altitude and turboprop runway margins

Standard temperature at 5,928 ft is about 3°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, 3°C)	5,928 ft	3,594 ft	2,735 ft	4,103 ft
Warm day (ISA +10)	7,128 ft	3,828 ft	2,862 ft	4,293 ft
Hot day (ISA +20)	8,328 ft	4,062 ft	2,989 ft	4,483 ft
35°C afternoon	9,751 ft	4,340 ft	3,139 ft	4,708 ft

Planning aid only. Even on a 35°C afternoon the longest runway (10/28, 5,728 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (4,708 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 K1U7 is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K1U7

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K1U7, 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 K1U7 or read what a fuel stop actually saves.
