Boundary County Airport serves Bonners Ferry, Idaho at 2,337 ft elevation with its longest runway, 02/20, at 4,000 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 2,337 ft is about 10°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, 10°C)	2,337 ft	2,894 ft	2,357 ft	3,535 ft
Warm day (ISA +10)	3,537 ft	3,128 ft	2,483 ft	3,725 ft
Hot day (ISA +20)	4,737 ft	3,362 ft	2,610 ft	3,915 ft
35°C afternoon	5,298 ft	3,471 ft	2,669 ft	4,003 ft

Planning aid only. On a 35°C afternoon the longest runway (02/20, 4,000 ft) is within 20 percent of the 1.5x landing figure for a Meridian-class turboprop (4,003 ft). Plan hot-day departures for the morning and check the POH. 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 K65S is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K65S

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K65S, 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 K65S or read what a fuel stop actually saves.
