Ontario International Airport serves Ontario, California at 944 ft elevation with its longest runway, 08L/26R, at 12,197 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.

02Density altitude and turboprop runway margins

Standard temperature at 944 ft is about 13°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, 13°C)	944 ft	2,622 ft	2,210 ft	3,314 ft
Warm day (ISA +10)	2,144 ft	2,856 ft	2,336 ft	3,504 ft
Hot day (ISA +20)	3,344 ft	3,090 ft	2,463 ft	3,694 ft
35°C afternoon	3,571 ft	3,134 ft	2,487 ft	3,730 ft

Planning aid only. Even on a 35°C afternoon the longest runway (08L/26R, 12,197 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,730 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 KONT is high, or as the longer runway on a hot afternoon.

Airport	Distance	Longest runway
KCNO Chino Airport	5 nm S	7,000 ft
KRAL Riverside Municipal Airport	10 nm SE	5,401 ft
KSBD San Bernardino International Airport	18 nm E	10,000 ft
KSNA John Wayne Orange County International Airport	26 nm SW	5,700 ft

04Jet A prices and FBOs at KONT

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