Gwinner Roger Melroe Field serves Gwinner, North Dakota at 1,266 ft elevation with its longest runway, 16/34, at 5,000 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.

01Runways

Runway	Length × width	Surface	Lighting

06/24	2,991 × 100 ft	turf	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,266 ft is about 12°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, 12°C)	1,266 ft	2,685 ft	2,244 ft	3,365 ft
Warm day (ISA +10)	2,466 ft	2,919 ft	2,370 ft	3,555 ft
Hot day (ISA +20)	3,666 ft	3,153 ft	2,497 ft	3,745 ft
35°C afternoon	3,970 ft	3,212 ft	2,529 ft	3,793 ft

Planning aid only. Even on a 35°C afternoon the longest runway (16/34, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,793 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 KGWR is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KGWR

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at KGWR, 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.
