Ochoa Field serves Othello, Washington at 1,149 ft elevation with its longest runway, N/S, at 4,500 by 40 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.

Private-use airfield. The FAA file marks this field private use. It is listed here for reference. Landing needs the owner's prior permission, and there may be no fuel or services. Do not plan it as a fuel stop or a routine alternate.

02Density altitude and turboprop runway margins

Standard temperature at 1,149 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)	1,149 ft	2,662 ft	2,231 ft	3,347 ft
Warm day (ISA +10)	2,349 ft	2,896 ft	2,358 ft	3,537 ft
Hot day (ISA +20)	3,549 ft	3,130 ft	2,484 ft	3,727 ft
35°C afternoon	3,825 ft	3,184 ft	2,514 ft	3,770 ft

Planning aid only. Even on a 35°C afternoon the longest runway (N/S, 4,500 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,770 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.
