Marshfield Municipal Airport serves Marshfield, Wisconsin at 1,277 ft elevation with its longest runway, 16/34, at 5,003 by 100 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 1,277 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)	1,277 ft	2,687 ft	2,245 ft	3,367 ft
Warm day (ISA +10)	2,477 ft	2,921 ft	2,371 ft	3,557 ft
Hot day (ISA +20)	3,677 ft	3,155 ft	2,498 ft	3,747 ft
35°C afternoon	3,983 ft	3,215 ft	2,530 ft	3,795 ft

Planning aid only. Even on a 35°C afternoon the longest runway (16/34, 5,003 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,795 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 KMFI is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KMFI

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