Grand Forks Air Force Base serves Grand Forks, North Dakota at 913 ft elevation with its longest runway, 17/35, at 12,350 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.

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.

02Density altitude and turboprop runway margins

Standard temperature at 913 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)	913 ft	2,616 ft	2,206 ft	3,309 ft
Warm day (ISA +10)	2,113 ft	2,850 ft	2,333 ft	3,499 ft
Hot day (ISA +20)	3,313 ft	3,084 ft	2,460 ft	3,689 ft
35°C afternoon	3,532 ft	3,127 ft	2,483 ft	3,724 ft

Planning aid only. Even on a 35°C afternoon the longest runway (17/35, 12,350 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,724 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.
