Allen Army Airfield serves Delta Junction Ft Greely, Alaska at 1,291 ft elevation with its longest runway, 01/19, at 9,000 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.

01Runways

Runway	Length × width	Surface	Lighting
01/19	9,000 × 150 ft	asphalt (good)	unlit
10/28	6,115 × 150 ft	asphalt (good)	unlit
07/25	4,057 × 88 ft	asphalt (good)	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,291 ft is about 12°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, 12°C)	1,291 ft	2,690 ft	2,246 ft	3,369 ft
Warm day (ISA +10)	2,491 ft	2,924 ft	2,373 ft	3,559 ft
Hot day (ISA +20)	3,691 ft	3,158 ft	2,499 ft	3,749 ft
35°C afternoon	4,001 ft	3,218 ft	2,532 ft	3,798 ft

Planning aid only. Even on a 35°C afternoon the longest runway (01/19, 9,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,798 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 PABI

There is no public FBO fuel to log at PABI. 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.
