Grissom Air Reserve Base serves Peru, Indiana at 812 ft elevation with its longest runway, 05/23, at 12,501 by 200 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 marked joint use. 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 812 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)	812 ft	2,596 ft	2,196 ft	3,293 ft
Warm day (ISA +10)	2,012 ft	2,830 ft	2,322 ft	3,483 ft
Hot day (ISA +20)	3,212 ft	3,064 ft	2,449 ft	3,673 ft
35°C afternoon	3,407 ft	3,103 ft	2,469 ft	3,704 ft

Planning aid only. Even on a 35°C afternoon the longest runway (05/23, 12,501 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,704 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 KGUS

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