Modesto City Co-Harry Sham Field serves Modesto, California at 97 ft elevation with its longest runway, 10L/28R, at 5,904 by 150 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.

10R/28L	3,464 × 100 ft	asphalt	lit

02Density altitude and turboprop runway margins

Standard temperature at 97 ft is about 15°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, 15°C)	97 ft	2,457 ft	2,120 ft	3,180 ft
Warm day (ISA +10)	1,297 ft	2,691 ft	2,247 ft	3,370 ft
Hot day (ISA +20)	2,497 ft	2,925 ft	2,373 ft	3,560 ft
35°C afternoon	2,520 ft	2,930 ft	2,376 ft	3,564 ft

Planning aid only. Even on a 35°C afternoon the longest runway (10L/28R, 5,904 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,564 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 KMOD is high, or as the longer runway on a hot afternoon.

04Jet A prices and FBOs at KMOD

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