Padgham Field serves Allegan, Michigan at 706 ft elevation with its longest runway, 11/29, at 4,300 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
11/29	4,300 × 75 ft	asphalt (good)	lit
15/33	1,830 × 150 ft	turf (fair)	unlit

02Density altitude and turboprop runway margins

Standard temperature at 706 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)	706 ft	2,576 ft	2,184 ft	3,277 ft
Warm day (ISA +10)	1,906 ft	2,810 ft	2,311 ft	3,467 ft
Hot day (ISA +20)	3,106 ft	3,044 ft	2,438 ft	3,657 ft
35°C afternoon	3,275 ft	3,077 ft	2,456 ft	3,683 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 4,300 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,683 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 K35D is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at K35D

No public API publishes FBO fuel prices, so JetDesk does not guess. Pilots and crews log the price they actually paid at K35D, 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 K35D or read what a fuel stop actually saves.
