Frankfort Dow Memorial Field serves Frankfort, Michigan at 633 ft elevation with its longest runway, 15/33, at 4,050 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 633 ft is about 14°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, 14°C)	633 ft	2,561 ft	2,177 ft	3,265 ft
Warm day (ISA +10)	1,833 ft	2,796 ft	2,303 ft	3,455 ft
Hot day (ISA +20)	3,033 ft	3,030 ft	2,430 ft	3,645 ft
35°C afternoon	3,185 ft	3,059 ft	2,446 ft	3,669 ft

Planning aid only. Even on a 35°C afternoon the longest runway (15/33, 4,050 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,669 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 KFKS is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KFKS

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