Dobbins Air Reserve Base serves Marietta, Georgia at 1,068 ft elevation with its longest runway, 11/29, at 10,002 by 300 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

110/290	3,495 × 60 ft	asphalt	unlit

02Density altitude and turboprop runway margins

Standard temperature at 1,068 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)	1,068 ft	2,646 ft	2,223 ft	3,334 ft
Warm day (ISA +10)	2,268 ft	2,880 ft	2,349 ft	3,524 ft
Hot day (ISA +20)	3,468 ft	3,114 ft	2,476 ft	3,714 ft
35°C afternoon	3,724 ft	3,164 ft	2,503 ft	3,754 ft

Planning aid only. Even on a 35°C afternoon the longest runway (11/29, 10,002 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,754 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 KMGE

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