Naval Outlying Field Imperial Beach (Ream Field) serves Imperial Beach, California at 24 ft elevation with its longest runway, 09/27, at 4,998 by 336 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.

Military airfield. This is a military airfield in the FAA file. It is listed here for reference and for emergency planning. Civil use needs prior permission, there is no FBO, and no Jet A you can buy. Do not plan it as a fuel stop or a routine alternate.

01Runways

02Density altitude and turboprop runway margins

Standard temperature at 24 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)	24 ft	2,443 ft	2,113 ft	3,169 ft
Warm day (ISA +10)	1,224 ft	2,677 ft	2,239 ft	3,359 ft
Hot day (ISA +20)	2,424 ft	2,911 ft	2,366 ft	3,549 ft
35°C afternoon	2,430 ft	2,912 ft	2,366 ft	3,550 ft

Planning aid only. Even on a 35°C afternoon the longest runway (09/27, 4,998 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,550 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.

04Fuel and services at KNRS

There is no public FBO fuel to log at KNRS. JetDesk collects Jet A prices that pilots actually paid, at civil fields, and its route finder leaves military and private-use fields out of every ranking. Read what a fuel stop actually saves.
