Roseau Municipal Rudy Billberg Field serves Roseau, Minnesota at 1,060 ft elevation with its longest runway, 16/34, at 4,400 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

06/24	2,097 × 250 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,060 ft is about 13°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, 13°C)	1,060 ft	2,645 ft	2,222 ft	3,333 ft
Warm day (ISA +10)	2,260 ft	2,879 ft	2,348 ft	3,523 ft
Hot day (ISA +20)	3,460 ft	3,113 ft	2,475 ft	3,713 ft
35°C afternoon	3,714 ft	3,162 ft	2,502 ft	3,753 ft

Planning aid only. Even on a 35°C afternoon the longest runway (16/34, 4,400 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,753 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 KROX is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KROX

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